Heat G of Robot Wars: The Fifth Wars was the seventh of twelve heats which determined the Semi-Finalists of Robot Wars: The Fifth Wars. The episode featuring Heat G was originally broadcast on May 14, 2002 on BBC Choice and repeated on August 23, 2002 on BBC Two.

  • Heat G was the fourth and last time that a lower seed won the heat, the other occasions being Heats B, J, and N of the Fourth Wars.
  • This heat was the only time Tornado failed to get past the heats, and it was the only top 12 seeded robot not to reach the heat final that series.
  • This heat marked the end of both Gravedigger and Diotoir's main series campaigns. Coincidentally, both robots fought Tornado in this heat.
  • Heat G was the marked occasion of several robots using weapons for one time, as Hydra wielded a flipping arm (without an axe), Sabre Tooth wielded a shredding weapon, and Gravedigger wielded a spiked axe.
  • Spawn Again vs Evolution is ranked equal 12th, at 21 seconds, in the Shortest Battles in UK Robot Wars. This battle was also Spawn Again's first Out of the Arena flip.
  • Evolution's battle with Sabre Tooth was a subject of controversy, because the House Robots attacked Evolution for no reason. As compensation, the judges put it through to Round 2.

Tornado (12) vs Gravedigger


The former semi-finalists lock horns

Gravedigger Axes Tornado

Gravedigger axes Tornado

Gravedigger missed its first blow with the axe but managed to get a few on Tornado. Tornado then got around the side of the wedge-shaped machine ramming it into the arena wall and then shoved it into another wall where its machinery stopped working. Gravedigger was then counted out by Refbot, Sir Killalot then took the Series 3 semi-finalist to the flame pit to be "cremated" and then dumped it into the pit where it was "buried".

Winner: Tornado

Diotoir vs Dome


The Dome rolls into submission

Immediately as the two machines approached each other (rather sluggishly), Diotoir overturned Dome with its scoop, where the latter couldn't self-right. The Irish robot then preceded to shove Dome down the pit, eliminating it from the competition and giving Diotoir an easy win.

"Dome... about as successful as the Millennium Dome."
— Craig Charles on Dome's poor performance

Winner: Diotoir

Evolution vs Sabre Tooth


Sir Killalot grapples with Evolution

Evolution started defending itself with the spinning blade with Sabre Tooth cautiously approaching it before charging into it. Sabre Tooth then lost its weaponry after striking Evolution's MDF side since the chain had come off. Both robots then ran rings around each other, before Sergeant Bash then came out of his CPZ and crumpled into the wooden bodywork of Evolution and then Sir Killalot also attacked Evolution, bending its turret which resulted in Refbot giving both house robots a yellow card. The fight then went to a judges decision, and on the benefit of the doubt awarded it to Evolution.

Winner: Evolution

Spawn Again (13) vs Hydra


Hydra is hurled by Spawn Again

Spawn Again quickly overturned Hydra but Hydra immediately recovered before driving onto the front of the Essex machine where it was thrown again but then self-righted for the second time. Spawn Again then threw Hydra on its back twice more where afterwards it stopped moving. Spawn Again then got Hydra near the wall where it was attacked by Matilda and then the 13th seed then tried to get Hydra over the fence but failed both times so left it to be dealt with by Sir Killalot and Matilda. Hydra was counted out and then taken to the pit of oblivion.

Winner: Spawn Again


Tornado (12) vs Diotoir


Diotoir overpowers Tornado to cause a major upset

Both dashed out, Diotoir missed its first flip on Tornado, Tornado then shoved the Irish machine near Sergeant Bash where it escaped being set on fire before dodging Sergeant Bash again. Tornado then rammed into Diotoir a few times ripping off bit of fur with its disc every time it hit Diotoir. The 2 robots then shoved against one another having a pushing contest before Tornado rammed Diotoir more times. After Tornado shredded more bits of fur from Diotoir, the Irish robot then proceeded to hit the pit release button and then Tornado seemed to have lost power, and Diotoir pushed it in the pit. Diotoir almost fell in afterwards, but had successfully shown Tornado just how much of an advantage a lot of experience can be. On the Tornado website, the team claimed that Diotoir's fur kept snagging its cutting disc, and ultimately ended up losing drive on one side, which allowed Diotoir to push them into the pit.

"Had it sensed that Tornado was on its last legs, as it were? What a shock this is! Diotoir, very nearly going in themselves, but Tornado, the twelth seeds, crash out!"
— Jonathan Pearce as Diotoir pits Tornado

Winner: Diotoir

Spawn Again (13) vs Evolution


Evolution goes out in 21 seconds

Before the battle, a brick was placed in the blade mechanism to make the weapon more powerful. As the battle started, Evolution spun its blade to defend itself from the Essex machine, but Spawn Again quickly came in and threw Evolution on its back where it couldn't self-right. Spawn Again then pushed the tank-like machine towards the arena wall where it was thrown clean out of the arena. The brick had reduced the effectiveness of the weapon by making it too heavy to spin properly.

Winner: Spawn Again


Spawn Again (13) vs Diotoir

As soon as activate was called, Spawn Again flipped Diotoir up and over, the Irish robot then in a failed attempt to right itself, made both of its eyes fly off. After Spawn Again pressed the pit release, the Refbot counted Diotoir out. Sergeant Bash came in and set the Irish machine on fire where it was put out by Refbot before Sergeant Bash set it alight again and was also attacked by Matilda, Spawn Again was the heat winner despite having its flipper jammed open throughout the majority of the fight after Diotoir had been overturned.

Heat Winner: Spawn Again

"If you're gonna burn a robot, then Diotoir's the one to burn, on Robot Wars!"
