- "Now this one can beetle about!"
- — Jonathan Pearce as The Stag entered the Arena in Series 6
The Stag was a robot that competed in Series 6 and 7 of Robot Wars. It lost in Round 1 in both of its appearances.
The robot's working name was Mr Hyde, but this was changed shortly before the Series 5 qualifiers. 
- "The aluminium shell, home-made speed controllers, hyrdraulic pincers, crushing at those 7 tonnes, a rear spike, oh and don't forget the chicken on the back!"
- — Jonathan Pearce sums up The Stag in Series 6
The Stag was invertible, two-wheel driven and designed to resemble a stag beetle and had hydraulic pincers as weapons that could crush with 7 tonnes of pressure, and a rear spike. It had an aluminium shell and home-made speed controllers, but the wheels were exposed.
The Stag had previously failed to qualify in the Fifth Wars. At the Series 5 qualifiers, it fought and beat Mega Hurts after scratching and denting, but not piercing, Mega Hurts' sides. The Stag then fought and drew against Lambsy, and also defeated Mute. Despite this performance, The Stag failed to qualify.
The Stag fought Shell Shock, Scrap Dragon and Gyrobot at the Series 6 qualifiers. Shell Shock broke down very quickly, and The Stag pushed it, whilst Scrap Dragon also broke down, having been rammed by The Stag and hit by Gyrobot repeatedly. Gyrobot started well, but also broke down, leaving The Stag as the winner, automatically qualifying for the series.
The Stag started well, gripping Wild Thing 2 and forcing it backwards while prising its claws underneath a layer of Wild Thing 2's armour. Wild Thing 2 retreated, and The Stag tried to attack UFO, but just as it got hold of it, Vader inflicted severe damage to The Stag, ripping off the rubber covering from one of its wheels. Vader then came in with another attack, which separated The Stag and UFO, and buckled The Stag's right claw. Wild Thing 2 then rode up the back of The Stag, causing damage to its shell and forcing it into Sir Killalot's CPZ. The Stag tried to move away from danger, but because of its now limited movement due to the damage caused by Vader it was only able to move around in circles. Sir Killalot then picked The Stag up, causing its mascot chicken to fall off, before spinning it around and placing it back onto the arena floor.
- "I think the chicken's come off. Did I see the chicken of The Stag, there, had come off? Well, I mean, that's it then, isn't it, really? It's powerless now..."
- — Jonathan Pearce
With The Stag still restricted in its mobility, Refbot decided to count it out, which left Sir Killalot and Sergeant Bash able to inflict further damage to the beaten machine. Sir Killalot opted to lift The Stag's mascot chicken by its neck, while The Stag continued to furiously spin around, before UFO decided to force The Stag down into the pit of oblivion just before cease.
The Stag charged into the centre of the arena after activate was called, but was immediately pushed backwards by Scorpion. The Stag spun around to move away from Scorpion, before clutching it with its claws. Scorpion worked its way free from The Stag's grasp, with IG-88 then crashing into the rear-end of a reversing The Stag with its bi-rotational axe. The Stag chased down Scorpion once more, before turning towards IG-88, where it sustained a full-frontal slam from IG-88, which threw The Stag up into the air and slightly warped one of its claws.
The Stag then made its way to the pit release button, successfully activating it at the second time of asking, before pushing Scorpion once more, as it was attacking the immobile Tomahawk. Scorpion and IG-88 then focused their attention on The Stag, and another strong attack from IG-88 threw The Stag upside down. The Stag responded by sliding underneath IG-88 and edging it backwards, before IG-88 came back onto the attack. Suddenly, in a bizarre turn of events, with IG-88 on the offensive, The Stag tried to retreat, but only succeeded in backing itself into the pit of oblivion.
- "Oh, what's happened to The Stag! It's reversed straight into the pit of oblivion! And we know that stag beetles can't self-right!"

This saw The Stag eliminated from the Seventh Wars along with Tomahawk.

Outside Robot WarsEdit
The Stag also competed in the 2003 series of Robot Wars' sister show Techno-Games as BeetleBot, working with Brutal Beetle in the football competition. They lost to Savage Toaster and Ickle Toaster 1-0 in the first round.
After Robot Wars ended, The Stag continued to fight in live events for a while, but over time Dave Martin lost interest in robot combat, and in 2011, the empty shell of The Stag, without electronics, was sold on eBay.
- "It's not really something i'm interested in anymore but I thought it was shame to let it go to the skip. So I thought I would let it go to someone that could use it."
- — David Martin on selling The Stag.
It is unknown who bought The Stag or who currently owns it, but since then, it has been seen on static display at ComicCon in Wales, alongside several other robots.
The Stag is set to appear later this year at the Welsh Comic con.
- In both of The Stag's battles, one of its opponents that defeated it was from Team Vader.
- In Series 6, a rubber chicken was displayed on the back of the robot.
