Round 1Edit

Bigger Brother (4) vs Colossus vs U.R.O. vs Typhoon 2Edit

Bigger Brother vs U.R.O.

Bigger Brother flips U.R.O.

Colossus Bigger Brother

Colossus is flipped over

Bigger Brother immediately pushed Colossus onto the pit release, and then flipped it into Sergeant Bash in the CPZ. Meanwhile Typhoon 2 attacked U.R.O., causing its side armour to come loose and then came off after an attack by Bigger Brother.


Typhoon 2 in peril

"There's trouble there for U.R.O. - we can see the innards, exposed."
— Jonathan Pearce as a side panel falls off of U.R.O.

Typhoon 2 continued to attack despite the fact that it wasn't spinning and Refbot counted Colossus out. Bigger Brother pushed U.R.O. into the CPZ and was then picked up by Sir Killalot, but was let go soon after. Bigger Brother then flipped Typhoon 2 over, but U.R.O. had already stopped moving so Refbot counted it out.

"And Bigger Brother has virtually beaten everyone here!"
— Jonathan Pearce

Having defeated all three of its opponents, Bigger Brother righted Colossus, but it had been counted out already. Typhoon 2 finally started spinning but it was unable to self-right. In the end, Colossus backed into the pit and Sir Killalot put U.R.O. in on top.

Qualified: Bigger Brother & Typhoon 2

DisConstructor vs Xenomorph vs Hammerhead 2 vs Iron-Awe 2.1Edit

Iron Awe flips Hammerhead 2

Iron-Awe 2.1 hurls Hammerhead 2 onto Xenomorph

The fight started with Iron-Awe 2.1 and DisConstructor chasing Refbot into the CPZ. Iron-Awe 2.1 then flipped Hammerhead 2, which landed on top of Xenomorph. Iron-Awe 2.1 flipped Xenomorph over as DisConstructor hit the pit release button and then drove straight in.

"OH, into the pit goes DisConstructor! No danger whatsoever, oh what on earth happened Mike Phillipson? Suddenly the pit yawned open underneath them and they were down."
— Jonathan Pearce
Iron-Awe Xenomorph

Xenomorph sustains damage from Iron-Awe 2.1's axe

Sir Killalot Iron-Awe

Iron-Awe 2.1 tussles with Sir Killalot

The rest of the fight was pretty uneventful, with Iron-Awe 2.1 flipping and axing Hammerhead 2 and Xenomorph numerous times, but both robots survived to the end of the battle. The House Robots intervened and Iron-Awe 2.1 tried to flip Sir Killalot, before knocking his eyes out with its axe.

"OH, Iron Awe tries to flip Sir Killalot and very nearly did so, and Sgt. Bash comes out and gives a little reminder - "Do not take on my troops son, extra square-bashing for you, Iron Awe"."
— Jonathan Pearce

Time ran out and the judges voted Xenomorph out along with the pitted DisConstructor.

Qualified: Hammerhead 2 & Iron-Awe 2.1

Round 2Edit

Bigger Brother (4) vs Iron-Awe 2.1Edit

Bigger Brother Iron-Awe

Bigger Brother flips Iron-Awe 2.1 over

Iron-Awe 2.1 vs Bigger Brother

Bigger Brother hoists Iron-Awe 2.1 aloft

Bigger Brother started stronger and flipped Iron-Awe 2.1, but then flipped it back over. This proved to be a big mistake as Iron-Awe 2.1 got a single flip in on Bigger Brother next to the side wall and the seeded machine landed on the arena wall, before toppling out of the arena, resulting in possibly one of the biggest upsets in Series 7.

Iron-Awe 2.1 throws Bigger Brother out

"Terrific battle. That's what Robot Wars is all about. Stack 'em, and pack 'em, rack 'em, and flip 'em... and Bigger Brother are out! The seeds have gone!"
— Jonathan Pearce as Iron Awe 2.1 flings Bigger Brother over the arena side wall

Winner: Iron-Awe 2.1

Hammerhead 2 vs Typhoon 2Edit

Hammerhead Typhoon 2

Typhoon 2 slams into Hammerhead 2

Typhoon 2 was now spinning properly and started the battle avoiding Hammerhead 2 in order to get up to full spinning speed. The two robots danced around the arena for a while before Typhoon 2 slammed into Hammerhead 2, deflecting it away. Another hit saw Hammerhead 2 lose drive on one side as well as some damage to the front. After a few more attacks by Typhoon 2, an entire panel came off the front of Hammerhead 2, which immobilised the Dutch machine. Refbot then counted it out.

"That's not a bad challenge, I tell you what, The Dutch machines are getting stronger and stronger in Robot Wars."
— Jonathan Pearce

Shunt then put it on the floor flipper. It flew a fair distance and more panels came off when it came down. Matilda then put it on the Drop Zone, where some railway track came down on it, and finally the house robots pitted the Dutch machine.

Winner: Typhoon 2


Iron-Awe 2.1 vs Typhoon 2Edit

Iron Awe Typhoon 2

Iron-Awe 2.1 sustains significant damage

Iron-Awe 2.1 entered the match at an immediate disadvantage, as a slippery substance had coated the floor for Sir Killalot's benefit, and could not gain strong traction on the arena floor. It still attempted to attack quickly, but Typhoon 2 ran away and span up to full speed immediately. Iron-Awe 2.1 came in for an attack, but was spun away spectacularly by the force of Typhoon 2's spinning blades. Another slam caused the front flipper on Iron-Awe 2.1 to buckle. Iron-Awe 2.1 headed for the pit release button but Typhoon 2 gave chase and caused more damage to its opponent.

The final blow from Typhoon 2

"I'm impressed, very impressed. He's worried, very worried!"
— Jonathan Pearce as the camera films Robert Grimm driving Iron-Awe

The flipper was now destroyed and CO2 came out the front of the robot. Another couple of slams by Typhoon 2 finally immobilised Iron-Awe 2.1.

"Iron-Awe get down that pit. Save yourself."
— Jonathan Pearce after Typhoon 2's final blow on Iron-Awe 2.1

Iron-Awe 2.1's run comes to an end as the stove crashes down on it

Refbot counted Iron-Awe 2.1 out, and Sir Killalot put it on the Drop Zone, where a gas cooker came crashing down on it. As a joke, Typhoon 2 came in and smashed the cooker as well.

"Typhoon 2 prefers a microwave, obviously."
— Jonathan Pearce
"It's taken over the mantle of Hypno-Disc!!"
— Craig Charles after Typhoon 2's heat victory

Heat Winner: Typhoon 2

"Typhoon strikes, and Iron-Awe's, just been blown, out of Robot Wars!"
— Craig Charles' sign-off

Special EventEdit

Main article: Robot Wars: The Seventh Wars/World Championship Qualifiers

Between Round 1 and Round 2 of each heat (except Heat I), a 'Special Event' was shown. For Heat O, it was a World Championship Qualifier between three Dutch robots; Gravity, Scraptosaur and Tough as Nails.

Winner: Tough as Nails

Trivia Edit

  • Iron-Awe 2.1's victory over fourth seed Bigger Brother is ranked within the thirty Shortest Battles in UK Robot Wars. Bigger Brother was the highest ever seed to be flipped out of the arena.
  • An editing error in the heat final showed the Drop Zone suspending a TV, before it dropped a cooker on Iron-Awe 2.1.
  • The World Championship Qualifier was a grudge match between Scraptosaur and Tough As Nails from Dutch Robot Wars, and also Scraptosaur and Gravity from the same series..
  • In the World Championship qualifier, Jonathan Pearce incorrectly said that Gravity had beaten the 13th seeds 13 Black, when it was actually seeded seventh.
