- "In the pits, friendship, but as we spin on, in the blink of an eye, death awaits, as the robot gladiators enter the arena! Welcome to Heat B of Robot Wars. It's enough to drive you crazy! The quick and the dead. They're all judged here fast, furious ... we're on fire!"
- — Jonathan Pearce's introduction
Heat B of Robot Wars: The Seventh Wars was the second of sixteen heats which determined the Semi-Finalists of Robot Wars: The Seventh Wars. The episode featuring Heat B was originally broadcast on November 9, 2003 on Five.
- This Heat contained four robots that would become very successful in Roaming Robots live events - Kan-Opener and Barbaric Response, in addition to future champions Big Nipper and Terrorhurtz. However, Kan-Opener fell in Round 1 for the third time in a row, and Barbaric Response also lost in Round 1. Meanwhile, Terrorhurtz, the third seed, was disqualified before it was due to fight, making Big Nipper the only Roaming Robots star in the heat to pass the first round.
- This Heat contained three judges decisions, all of which contained The Grim Reaper. The only two matches not to go to the judges contained Jackson Wallop.
- The two Heat Finalists in this Heat lost to the winner and runner-up of Series 5 (Razer and Bigger Brother) in their only other appearances.
- This Heat featured the first occasion of the Arena Floor Flipper flipping a robot out of the arena, flipping out the featherweight G2 in the Special Event.
- This Heat featured only one newcomer in Gyrobot.
- This episode was released on DVD by The Sun to promote Jetix and Fox Kids.
- After the second melee, the board displaying the results wrongly showed that Killerkat, rather than Gyrobot, had qualified along with Jackson Wallop.

Kan-Opener vs The Grim Reaper vs Big Nipper vs Barbaric ResponseEdit
The Grim Reaper quickly tried to get underneath Kan-Opener, but was unable to flip it. Meanwhile, Barbaric Response had more success in getting underneath Big Nipper and tossed it a short distance across the arena. Kan-Opener then grabbed hold of Barbaric Response, while The Grim Reaper tried to flip the Barber family's machine. The Grim Reaper then flipped Big Nipper over, but it was invertible and carried on going.
- "That's a good little duel going on in there between the two of them, evenly matched."
- — Jonathan Pearce on The Grim Reaper and Big Nipper's tussle
The Grim Reaper then wedged under Big Nipper and pushed it into the arena wall while Barbaric Response, still being gripped by Kan-Opener, was pushed around the arena. Big Nipper then used its lifting weapon to get underneath The Grim Reaper and pushed it into an angle grinder, but The Grim Reaper escaped. Big Nipper then turned its attentions to Barbaric Response, which was still being held by Kan-Opener, despite the attempts by Growler to separate the machines.
- "Barbaric Response, the meat in the sandwich."

Growler then activated the pit release button with all four robots perilously close to the edge of the pit, but Big Nipper and The Grim Reaper scampered away to continue their duel. Kan-Opener desperately tried to push Barbaric Response into the pit in the last few seconds, but Barbaric Response resisted and cease was called. As The Grim Reaper's mascot watched over the judges' table, the judges made their decision and went for The Grim Reaper and Big Nipper.
Qualified: Big Nipper & The Grim Reaper
Terrorhurtz (3) vs Jackson Wallop vs Gyrobot vs KillerkatEdit
Before the battle, Terrorhurtz arrived at the studio unfinished, and the producers disqualified it on the grounds that all robots had to be complete and combat ready upon arrival.
- "Already the major shock then, the number 3 seeds have gone out."
- — Jonathan Pearce as Terrorhurtz's disqualification is confirmed
The battle itself started slowly as the three remaining robots all needed time to charge up their spinning weapons. Killerkat and Jackson Wallop eventually came together, and almost immediately, Killerkat lost drive to one side. Gyrobot then attacked Killerkat, having charged up to full spinning speed, and caused further damage to Killerkat, seemingly allying with Jackson Wallop. Gyrobot and Jackson Wallop both attacked Killerkat with their spinning weapons and Killerkat stopped moving altogether. One more attack from Jackson Wallop threw Killerkat onto its side and Gyrobot pushed it onto the flame pit, setting its fur on fire as Refbot counted it out.
- "Oh don't spoil the fun, get it on the flame pit! That's it! Bring fur into the arena, you've got to expect this!"
- — Jonathan Pearce urgers Gyrobot and Jackson Wallop to set Killerkat on fire
Killerkat was then placed on the arena flipper and thrown across the arena before cease was eventually called. Jackson Wallop and Gyrobot qualified, having only needed to defeat one robot together.
Qualified: Gyrobot & Jackson Wallop
Gyrobot vs The Grim ReaperEdit
The Grim Reaper started quickly and flipped Gyrobot before it had a chance to spin up to full speed. The invertible Gyrobot moved towards the CPZ, where it was flipped once again by The Grim Reaper and both robots escaped from Sir Killalot. Gyrobot kept backing away from its opponent in an attempt to get up to full spinning speed, but The Grim Reaper pursued it and flipped it once again, before slamming it into the arena wall. The Grim Reaper then pushed Gyrobot into the CPZ, where it was met by Sir Killalot and Cassius Chrome, but it was able to escape.
- "For me, it's all The Grim Reaper, and Gyrobot, defensively? What do you call that tactic? I think it's called running away, that's it..."
- — Jonathan Pearce as Gyrobot continues to retreat
Gyrobot continued to run away from The Grim Reaper and slammed into the arena wall in the process. The Grim Reaper then activated the pit release button, and continued to flip Gyrobot around the arena. The Grim Reaper pushed Gyrobot into the arena wall, and tried to flip it out of the arena, but was unsuccessful. Cease was called with both robots still active and the judges went for The Grim Reaper.
Winner: The Grim Reaper
Big Nipper vs Jackson WallopEdit
Jackson Wallop moved towards Big Nipper, but its spinning arm was too high off the ground to hit Big Nipper. Jackson Wallop then backed away and slammed into the arena wall three times, destroying the pit release button on the third impact. Big Nipper then pushed Jackson Wallop into an angle grinder but Jackson Wallop escaped. Big Nipper ran into Jackson Wallop again, wedging one of its claws into Jackson Wallop's tyre in the process, causing the tyre to fall off the machine. Jackson Wallop now had very little control and came under attack from Shunt and Dead Metal, taking heavy damage from the latter.
- "And the draw, to be honest, for this second round, defeated Jackson Wallop. They could never get any advantage over Big Nipper."
- — Jonathan Pearce
Big Nipper then slammed Jackson Wallop into the corner of the arena, and Jackson Wallop took further damage from Dead Metal. Finally, Dead Metal grabbed hold of Jackson Wallop and pushed it into the pit of oblivion.
Winner: Big Nipper
The Grim Reaper vs Big NipperEdit
Big Nipper got its lifting arms underneath The Grim Reaper and carried it across the arena, before The Grim Reaper fell off. The Grim Reaper then flipped Big Nipper over in the CPZ and Cassius Chrome came in to attack.
- "A rattling good display so far, from both these machines."
- — Jonathan Pearce
The Grim Reaper continued to flip Big Nipper over, but Big Nipper kept on going and got underneath The Grim Reaper once again, pushing into the CPZ and up against the arena wall.
- "And Big Nipper, slowly and surely, has put The Grim Reaper up on its end."
- — Jonathan Pearce as Big Nipper tips The Grim Reaper onto the arena side wall
The Grim Reaper used its flipper to right itself but then took damage from Sergeant Bash. The Grim Reaper escaped but Big Nipper pushed it back into the CPZ and then ran away, with The Grim Reaper quickly pursuing. Big Nipper then got underneath The Grim Reaper and pushed it into the arena wall one more time before cease was called.
- "Big Nipper; I think is on top. Not physically, but I think they ended in the ascendancy."
- — Jonathan Pearce, as the battle reaches its conclusion
The decision went to the judges and they went for The Grim Reaper, on the basis of higher aggression, to the disagreement of Craig Charles and Jonathan Pearce.
Heat Winner: The Grim Reaper
- "Poor old Big Nipper, couldn't get its claws, around the grimmest of reapers, on Robot Wars!"
- — Craig Charles' sign-off
- Main article: Robot Wars: The Seventh Wars/Featherweight Championship
