"...We've found a robot who is quite simply colossal! With evil flowing through his metal veins, ladies and gentlemen, boys and girls, with his bulldog Growler, meet the deadly Mr. Psycho"
Craig Charles introduces Mr. Psycho for the first time in Heat A of Series 6

Mr. Psycho was a House Robot who made his debut in the sixth series and was designed by Robin Englebright. Mr. Psycho was by far the heaviest of the House Robots in the original run, weighing in at 750kg, and the largest robot ever to appear in Robot Wars history. He was based on Bill Sykes, a character from the Charles Dickens novel Oliver Twist, and his original working name during the design process was Psychsy. Mr. Psycho was also introduced with Growler, a robot which was a take on Bill Sykes' dog, Bullseye.

As the heaviest House Robot, Mr. Psycho could be seen as the leader of the House Robots across Series 6-7, directly replacing Sir Killalot - however, he did not return when Robot Wars was rebooted in 2016.



Design sketches for Mr. Psycho, some of which featured two claws

Mr. Psycho was powered by 36 volt motors and 12 batteries and was armed with a 30kg heavy pneumatic hammer that travelled at 60 mph and a hydraulic claw capable of exerting pressures of up to 9 tonnes. Some of Mr. Psycho's early design sketches featured two hydraulic claws and no hammer, but this was rejected.

Mr. Psycho Size

The size of Mr. Psycho, in comparison to the Robot Wars technical team and Judges.

His design was very similar to that of Sir Killalot, featuring caterpillar tracks and a powerful claw weapon. The design differed from Sir Killalot in that Mr. Psycho had a swinging hammer weapon instead of the lance that Sir Killalot wielded; the head of the hammer alone weighed 30kg and had a hydraulic accumulator and was powered by a 9 ton shoulder and elbow ram. His claw was powered by two 9 ton hydraulic rams running at 3000 psi (21 MPa). He ran on caterpillar tracks of the same type used for Sir Killalot. These tracks were powered by two Briggs and Stratton 5hp electric motors run at 48 volts, which were controlled by two 300 ampere speed controllers. The chassis was constructed from thick walled steel box section and the head was fabricated in fibreglass.

At 750kg, Mr. Psycho was the joint heaviest robot in the history of Robot Wars. Despite this, he was not invulnerable to being flipped, having been flipped by Firestorm 4 in Extreme Series 2 and toppling over while carrying Junkyard Queen in the German Series.

Robot HistoryEdit

Series 6Edit

"One man and his dog - Robot Wars' most powerful punishing pair EVER!"
— Jonathan Pearce during Mr Psycho and Growler's introduction

Mr Psycho was introduced along with Growler at the start of Heat A, as part of the house robot introductions. Mr Psycho entered the arena along with Growler, where the two span around and demonstrated their weaponry for the crowd. The two new House Robots made their combat débuts together during Razer's Round 2 battle against Cyrax.

"And here, for the first time ever in Robot Wars, the giant new House Robots Mr Psycho and Growler, weighing in at over 1000 kilos between them! Mighty, menacing, fearsome, formidable!"
— Jonathan Pearce as the new House Robots enter the arena before the battle
Psycho vs Cyrax

Cyrax becomes Mr. Psycho's first victim

In the battle, Cyrax drove dangerously close to Mr. Psycho whilst reversing away from Razer, but not close enough for him to attack before Razer got under Cyrax and pushed it onto the flame pit.

"Oh, please, don't go there - don't go towards Mr. Psycho."
— Jonathan Pearce gives Cyrax some key advice

Razer then steered Cyrax into his CPZ, allowing Mr. Psycho to make his first proper attack. He slammed the hammer on the top of Cyrax, smashing the outer lens cap on the blue robot's blinking light, then landed another blow, hitting the rear armour.

"Oh, down it comes! The huge 30 kilo club, and literally smashing Cyrax to pieces"
— Jonathan Pearce

Mr. Psycho and Growler were also used in the next battle, between Tetanus 2 and Raging Reality. However, Mr Psycho did not play a part, despite driving towards the two competitors when they drove into an empty CPZ, Growler got there before him, so Mr. Psycho held back, then returned to the CPZ.

Mr. Psycho's next appearance was in another Round 2 battle, and was teamed with Growler again, in the Heat B battle between Firestorm 4 and Barbaric Response. The House Robots were not involved in this battle, and although Mr. Psycho did approach the immobile Barbaric Response, cease was called before it could attack.

Mega hurts mr psycho

Mr. Psycho slams the remains of Mega Hurts 2's monitor

Mr. Psycho also appeared in the other Round 2 battle, again paired with Growler, during the battle between X-Terminator and Mega Hurts 2. After Mega Hurts 2 was pushed into an empty CPZ by X-Terminator, Mega Hurts 2 was too slow to get away, and Mr. Psycho hit the computer monitor and the robots front with his hammer, but did no major damage. X-Terminator pushed Mega Hurts 2 into Mr Psycho again in the last few seconds, who hammered it again, and tried to grab it with his claw, but could not grip it due to its shape, though it did manage to pin Mega Hurts 2 down, and rip the side a little.

"That's the power of these robots in this series."
— Jonathan Pearce

Mr. Psycho made two more second round appearances in Heat C, this time with the second-heaviest House Robot, Sir Killalot, but did not play any role in either battle.

"Message here: don't mix it with the House Robots!"
— Jonathan Pearce before the battle with Chaos 2 and Dantomkia
Mr Psycho S3

Mr. Psycho worries S3

He appeared in a first round melee for the first time in Heat D, where he hammered the immobile Roobarb after it broke down in a CPZ, breaking the top armour. However, the hammer did not retract properly, and was left dangling halfway up, until he fired it again, after which it did retract. Later in the same battle, Mr. Psycho pinning S3 in a CPZ after Shredder pushed it in, also hammering the wheel and armour, damaging a gearbox shaft. Although Mr. Psycho did not immobilise S3, it caused significant damage which took heavy repairs to fix.

Heat E was the first episode Mr. Psycho did not appear in since his debut, and he made only one appearance in Heat F, during the Round 2 fight with Stinger and Fluffy. After Fluffy limped into an empty CPZ, Mr. Psycho rushed in and hammered it, then missed another blow as Fluffy escaped. Later in the same battle, he pushed the immobile Fluffy onto the floor flipper.

Mr. Psycho was absent for the next few Heats, until appearing in the first round of the last heat of The Sixth Wars, Heat L, where he was again paired with Sir Killalot. In this battle, Mr. Psycho hammered Riptilion after Bigger Brother pushed it towards him, then went for Major Tom after Bigger Brother pushed it into the CPZ, completely buckling the rollbars with his hammer.

"it's not the quickest around the arena, but when he has you in his sights, oh! That hammer is genuinely awful!"
— Jonathan Pearce as Mr. Psycho hammers Major Tom
Psycho Dantomkia

Dantomkia is hammered by Mr. Psycho

In the first Semi-Final, Mr. Psycho appeared in the battle between Dantomkia and Razer, again partnered with Sir Killalot. In this battle, Razer forced Dantomkia into Mr. Psycho's CPZ, and although Dantomkia managed to turn Razer in as well, Mr. Psycho hammered Dantomkia.

Mr Psycho Spawn Again

Mr. Psycho lifts Spawn Again up into the air

In the second first Semi-Final, Mr. Psycho was paired with Dead Metal for the fight between Tornado and Hypno-Disc, but was not involved in the fight. He also helped finish off a battered Spawn Again during its battle against Terrorhurtz, as he picked it up and paraded it around, before dropping it by the pit and allowing Dead Metal to nudge it down.

"Mr ugly, is Mr. Psycho of course. Mr gruesome, is Mr. Psycho. Mr merciless, is Mr. Psycho. Imagine him as your Uncle. Imagine him as your teacher. Imagine him as the boy next door."
— Jonathan Pearce as Mr. Psycho puts Spawn Again on the pit's edge before letting Dead Metal push it in

It was paired with Sir Killalot for the losers' melee, but played no part.

Mr. Psycho's only appearance in the Grand Final was in the battle between Tornado and Firestorm 4, but again, it remained out of the action.

"The mightiest machine ever in Robot Wars!"
— Jonathan Pearce during the UK vs Germany Special

Mr. Psycho also appeared in the UK vs Germany Special, where it hammered the side of the beaten 259 machine during its battle with Fluffy, bending the chassis. Mr. Psycho also used its hammer to help loosen Sgt. Bash's grip on Delldog in its fight against Das Gepäck, before reigning down blows on the immobile robot.

"Teamwork from the House Robots! Now, you understand that they're totally neutral in all this. They don't mind if UK or Germany wins this."
— Jonathan Pearce

In the Final, Mr. Psycho appeared alongside Sgt. Bash, but was not involved.

Extreme 2Edit

"Gruesome as ever!"
— Jonathan Pearce introduces Mr. Psycho in Heat B of the All-Stars

Mr. Psycho's first appearance this series was in Heat B of the All-Stars tournament, in the battle between Bigger Brother, Firestorm 4 and S3, but the House Robots were not involved in the battle.

Mr Psycho Chaos

Mr. Psycho holds Chaos 2 in his grip

"That just gives you some sense of Mr. Psycho's size out there. He is immense! It's [Chaos 2] just a mere bauble, a toy, in the grip of Psycho!"
— Jonathan Pearce as Mr. Psycho carries Chaos 2 to the pit

In the All-Stars tournament, Mr. Psycho featured in the battle between Chaos 2, Razer and 13 Black, and after Chaos 2 was counted out, he pushed the former champion on the floor flipper where it was thrown, before hitting it with his hammer and then plucking it from the ground, parading it around the arena and pushing Chaos 2 into the pit - carrying out his first pitting of a competitor robot in the process.

Mr Psycho Major Tom 1

Mr. Psycho destroys Major Tom

Mr. Psycho and Matilda carried out a merciless assault on Major Tom after it broke down in Round 4 of the Annihilator, with Mr. Psycho using his hammer to bend and break the roll-cage, and hammer the top, causing the face and crown to fall off, then ripped the head with his claw. Mr. Psycho then picked up Major Tom and place it on the Drop Zone.

Killer carrot 2 and mr psycho

Mr. Psycho overpowers Killer Carrot 2

After losing a wheel, which Mr. Psycho picked up with his claw, a struggling Killer Carrot 2 tried in vain to fend off Mr. Psycho during its Minor Meltdown battle against Lambsy.

"Killer Carrot are in trouble, major trouble here. Mr. Psycho has them in his sights. Turning, trundling, climbing up."
— Jonathan Pearce as Mr. Psycho closes in on Killer Carrot 2

It overbalanced itself by trying to flip Mr. Psycho, who proceeded to hammer Killer Carrot 2 and ride up the front of it.

Barbaric response mr. psycho

Mr. Psycho knocks Barbaric Response's back panel loose and bends its weapon

Mr. Psycho appeared in the final of the Tag Team Terror, a battle in which he wrecked havoc on the beaten pair. First, he hammered Hydra, then picked it up, holding over the flame pit before dropping it into the pit, before striking Barbaric Response with a significant hit of his hammer, as he knocked a whole panel off and buckled the top part of its weapon.

For the New Blood Championship, Mr. Psycho and the other House Robots were allowed to do more damage than usual to immobilised competitors.

"A real baptism of fire - none of the "Mercy Clauses" that the usual competitors get to sign, if you lost in this your machine was going to be thoroughly trashed by the House Robots, there was even a briefing given before the competition explaining what was in store."
— Team Storm Website[1]
Mr Psycho Maximus

Maximus is damaged by Mr. Psycho

Mr. Psycho played a very active role in the New Blood Championship, and continued to cause notable bodywork damage in Heat A, bending Maximus' spikes with his hammer and buckling its flipper as he grabbed it with the claw.


Night Raider, stuck between the jaw of Killalot and the claw of Mr. Psycho

He then enjoyed a very busy Heat B, as he consigned Night Raider to multiple damaging hits from his hammer before it was counted out. Mr. Psycho picked it on with his claw, placing it onto the floor flipper where it was thrown, actually hitting Mr. Psycho as the House Robot tried to reverse. One last hammer blow saw more pieces of armour fall off.

In the other Round 1 melee in that heat, Mr. Psycho pushed the walker RT81 into the centre of the arena where its opponents were fighting.

"RT81 pushed out into the arena centre, give it a chance to get out there amongst the melee otherwise it would have taken to the year 2086."
— Jonathan Pearce
Mr Psycho Edgehog

Mr. Psycho drives Edge Hog across the arena floor

Mr. Psycho pushed it straight into front of Edge Hog, which axed it repeatedly, until the two got stuck together, at which point Mr. Psycho and Sir Killalot pushed the two in an attempt to separate them. Edge Hog eventually got its axe free, but was left moving on one wheel by Mr. Psycho's CPZ. Mr. Psycho hammered Edge Hog, and with Edge Hog unable to move away, it reversed into the giant House Robot, lifting the head as it raised the axe. Mr. Psycho rammed Edge Hog into the opposite arena wall in return.

"Took one on the chin there, he doesn't look very happy - he's after you!"
— Jonathan Pearce warns Edge Hog of Mr. Psycho's wrath

Mr. Psycho then turned back to RT81, which was not moving, slamming it into the arena side wall, where it was counted out.

Mr. Psycho appeared with his dog Growler in the Round 2 battle between Chip and Thor. Mr. Psycho hammered the immobile Chip, then rammed it to the top of the arena where Growler was fighting Thor, before ramming Chip into an angle grinder. As the pit opened, Mr. Psycho nearly reversed in.

"Get down there! You'd never get him out!"
— Jonathan Pearce
Mr Psycho ICU

ICU is hammered by Mr. Psycho

In Heat C, Direct Action turned into Mr. Psycho's CPZ, after being slammed into the arena wall by Storm 2. Mr. Psycho missed a hammer blow on Direct Action, and Direct Action turned around, trying to escape, it turned into Mr. Psycho's hammer, cutting a gash in it. This cut was never repaired, and can be seen in Series 7.

In the same battle, Mr Psycho managed to land a hammer blow on Storm 2 as it passed, but the hammer did no damage. In the Heat Final, Mr. Psycho subjected ICU to multiple blows and placed it on the floor flipper after it was immobilised.


Doctor Fist is roasted and hammered

In the first round of Heat D, after Doctor Fist had broken down, he came in, missing a hammer blow. As he tried again, Matilda charged again, hitting Doctor Fist with the flywheel. This caused Mr. Psycho to miss the competitor and hit the angle grinder instead, also catching Matilda a little.

"I think he just missed the spinning rear flywheel of Matilda."
— Jonathan Pearce

Mr. Psycho then picked Doctor Fist up with the claw by one of its wheels, and held it over the flame pit.

"Huge power, hoisted way, way above the arena. Mr. Psycho, when standing like that, towers over me"
— Jonathan Pearce as Mr. Psycho holds Doctor Fist over the flames

As the House Robot tried to drop Doctor Fist, the whole body fell off the wheel. As Doctor Fist burnt, Mr. Psycho hammered it again.

Mrpsycho cedric

Mr Psycho carries Cedric Slammer

Mr. Psycho appeared twice in the New Blood Grand Final, first in the eliminator battle between Storm 2 and Thor, where, after reversing too close to the CPZ, Storm 2 pushed Thor into Mr. Psycho, who blocked its escape and hammered it. In the other eliminator between Mute and Cedric Slammer, after both robots had stopped moving, he picked Cedric Slammer up and carried it around the arena in the last few seconds before the battle went to the judges.

"...Mr. Psycho thinks Cedric Slammer is still fighting and therefore he can attack Cedric Slammer! So does the contest go on? This is very controversial!"
— Jonathan Pearce as Mr. Psycho carries Cedric Slammer

Mr. Psycho did not appear in any of the lower weight class events show in the Robot Rampage. He was also absent from the University Challenge

Mr Psycho Dantomkia

Mr. Psycho presses Dantomkia up against the arena wall

Mr. Psycho played an active role in a first round melee involving Dantomkia, S.M.I.D.S.Y., Sir Chromalot and Hypno-Disc in the Challenge Belt. First, after Dantomkia pushed Hypno-Disc into the CPZ and flipped it out of the arena, he rammed Dantomkia against the arena wall a couple of times and blocked its escape for a while.

"Dantomkia needs to get away from Mr. Psycho, could literally crush it in that CPZ!"
— Jonathan Pearce as Dantomkia attempts to escape the CPZ

Later, after Dantomkia flipped S.M.I.D.S.Y. onto the arena entry gates in one of the top CPZ's, Mr. Psycho picked it up and threw it aside, nearly throwing it out of the arena. S.M.I.D.S.Y. fled to a CPZ on the other side of the arena, where Mr. Psycho drove on top of it.

Mr Psycho Riptilion 1

Riptilion is slammed into submission

Riptilion was involved in another encounter with Mr. Psycho in the Iron Maidens, as the House Robot hammered it after it was counted out. Kat 3 tried pushing it into the pit, but Riptilion's wide shape and side spikes stopped it from falling in, so Mr. Psycho pushed it in fully, then gave it another hammer blow.


Mr. Psycho attacks Bondi Titch

In Round 1 of the Commonwealth Carnage, after Bondi Titch was flipped against the arena wall in the CPZ by Firestorm 4, Mr. Psycho blocked its escape and hammered it.

"Battle of the hammers. Ha! There is no match! Hammer? That's a hammer on Mr. Psycho!"
— Jonatahn Pearce compares the hammers of Bondi Titch and Mr. Psycho

After a number of hammer blows, Bondi Titch manage to swerve around the huge House Robot and escape.

Firestorm IV vs Sgt Bash

Mr. Psycho holds Panic Attack while Firestorm flips Sgt. Bash

During the semi-final, after Panic Attack was unable to self-right, Mr. Psycho picked it up, carried it around the arena, and held it over the flame pit. Firestorm then started trying to get under the colossal House Robot, so Mr. Psycho dropped Panic Attack and chased after Firestorm.

"Six foot two, eyes of blue, Mr Psycho's after you!"
— Jonathan Pearce as Mr Psycho exacts revenge on Firestorm
Firestorm flips Mr Psycho

Firestorm flips Mr. Psycho

Mr. Psycho then went back to attacking Panic Attack, picking it up and carrying it to the pit, into which it was dropped. Firestorm managed to topple Mr. Psycho over when he reversed onto the wedge whilst driving away from the pit, becoming one of only two robots to do so, and the only one to do it intentionally.

"Can they do it? Look at Mr. Psycho, that is a huge weight! Mr. Psycho saved by the cease? NO! Timber! That's a first! Who on Earth is gonna to raise Mr. Psycho up onto his feet? It'll take an army!"
— Jonathan Pearce as Firestorm 4 flips Mr. Psycho over

Before this, Firestorm flipped over Sergeant Bash, and with Panic Attack already immobilised, Refbot was the only robot still mobile at the end of the battle bar Firestorm.

Zeus Mr Psycho

Mr Psycho carries Zeus

Mr. Psycho also appeared in the final episode of Extreme 2, and finished off the series with a strong showing. In the battle between Black Hole and Zeus, he hammered the beaten Zeus, before picking it up and dropping it into the pit.

— Jonathan Pearce uses a little Italian as Mr. Psycho pits Zeus
Mr Psycho Snake Bite

Snake Bite suffers damage from the hammer of Mr. Psycho

Then, in the battle between Tornado and Snake Bite, he drove up the Swiss robot's wedge after it broke down, and slammed a significant dent into the back after it had been pitted.

Mr Psycho Rip

Mr. Psycho crumples Rip with his claw

Mr. Psycho's first notable involvement in Robot Wars: The Seventh Wars came in the Featherweight Championship in Heat B, as he joined Sir Killalot and Growler in the arena. The House Robots were given a significant amount of freedom to do as they pleased throughout the battle, and Mr. Psycho took advantage of this as he grabbed and buckled Rip with his claw before slamming down onto Cygnus.

Barber-Ous pitted

Barber-Ous 2'n a Bit is swept into the pit by Mr. Psycho

Psycho was involved in another special event in Heat C, as he inadvertently swept Barber-Ous 2'n a Bit into the pit during the Battle of the Spinners. He also dropped Barber-Ous 2'n a Bit into the pit after its loss in the first round of Heat E.

Mr. psycho drops out Hassocks hog 2

Mr. Psycho drops Hassocks Hog 2 out of the arena

Mr. Psycho achieved his only Out of the Arena after dropping Hassocks Hog 2 out of the arena in Heat C. He originally dropped Hassocks Hog on the Drop Zone, but it was unintentionally knocked away by the competitors before an item could drop. Similarly, in Heat P, Mr. Psycho placed Zorro on the Drop Zone after it had been counted out, but Zorro landed on its wheels and drove away. Psycho eventually caught it, and dropped it into the pit.

"Pinser, wakey-wakey, you too. Okay, look, now, you've beaten Cobra, but that thing there - see it? Little thing there? It's Mr. Psycho - get out of the way!"

Psycho also hammered the likes of Kronic the Wedgehog, T-Wrecks and Behemoth in Heat J, Heat K and Heat L respectively, while he carried out floor flipper, drop zone and pitting duties on beaten robots including Hard, UFO, Spin Doctor, Mega Morg and NEATer Machine in Heat K, Heat L, Heat M and Heat N.

"Mr. Psycho has lost... what little brains he had."
— Jonathan Pearce
Mr Psycho & Topbot

Mr. Psycho loses his head

During an eliminator in the Heat N, a strike from Mr. Psycho's hammer on Topbot caused his already wobbling head to fall off. Mr. Psycho went berserk for a while, hammering The Executioner into submission with his hammer, before dropping it into the pit shortly before cease was called.

Psycho and Gravity

Mr. Psycho flattens Gravity

Along with Growler, Cassius Chrome and Refbot, Mr. Psycho appeared in the Series 7 House Robot Rebellion as the House Robots faced off against Gravity and Behemoth. After Growler and Cassius Chrome were put out of action - until Refbot righted Cassius Chrome - Psycho took revenge on Gravity, immobilising it by battering its top with his hammer. Behemoth tried to fight back, but was slammed into the arena wall by Psycho and had its axe snapped off as it was trying to damage the House Robot. Behemoth then tried to use Gravity as a shield against Psycho, but to no avail. However, Psycho brokedown near the end of the battle, and Behemoth and Gravity were given the victory via a decision from the audience.

Mr Psycho Pussycat

Mr. Psycho punishes Pussycat

Mr. Psycho appeared alongside Cassius Chrome in the All-Stars final, a battle in which both House Robots fought back against the winner, Pussycat, after it decided to attack them, and both Dantomkia and Pussycat ended up in the pit thanks to a nudge from Mr. Psycho.


The first defeat of Mr. Psycho.


Mr. Psycho also appeared in the second series of Dutch Robot Wars as well as German Robot Wars. The most memorable moment occurred in the Grand Final of the German Wars, when Mr. Psycho picked up Junkyard Queen during its battle against Not Perfect. Mr. Psycho paraded Junkyard Queen around the arena until he took a corner too quickly and toppled over.
