"On the front line so far, Atomic thrown off course. Chaos 2 through to the series semi-finals joined by Pussycat, killing Robochicken and then blunting Razer. Firestorm had a visit to The Morgue but came out alive. Only just as the judges marking stormy seeds and gave them the nod. Steg 2 then upset the odds against seeded Mortis and Dominator 2 against 101 won so let's rev up for more ferocious fun!"
— Jonathan Pearce's introduction

Heat F of Robot Wars: The Fourth Wars was the sixth of sixteen heats which determined the semi-finalists of Robot Wars: The Fourth Wars. The episode featuring Heat F was originally broadcast on November 3, 2000 on BBC Two. The broadcast managed to attract 3.45 million viewers, a decrease of 1.23 million viewers when compared with the previous episode. According to BARB, this meant it fell to thirteenth in the top thirty highest rated BBC 2 broadcasts during 30 October-5 November.

"The thing I really hated about school was having to play rugby, being cold, wet and miserable while a bunch of sweaty sixth formers pummeled the living daylight out of me. And that was just in the showers. And then there was swimming, where they teach ya how to swim in the sea by making you pick a rubber brick off the bottom of the pool. Now, call me lazy, but if I fall off a boat, then that’s where the brick is gonna stay, all right! Now, luckily for me, ‘games’ now means Robot Wars, and it may be just as brutal, but at least if I forget me kit, they don’t make me play in me underpants."

Gemini (8) vs Tornado vs Kater KillerEdit

Tornado,gemini kater killer

Tornado rams Kater Killer into Gemini.

Katerkiller overturned

Kater Killer tries to self right

At Activate, Gemini split while Tornado rammed Kater Killer across the arena into Refbot. Tornado pushed Kater Killer towards Sir Killalot, which tapped the cat based robot with his claws. Tornado drove near Gemini whilst Kater Killer moved towards Gemini. Tornado rammed Kater Killer again, pushing it across the arena along with one of Gemini which did a wheelie. The other twin tried to attack Kater Killer only to do a wheelie before the other twin flipped Kater Killer as Tornado pushed it, over turning the tracked machine onto the top of Tornado.

"Kater Killer flipped up and over. Has the lifting arm, can it self-right? I don't think so."
— Jonathan Pearce
Shunt vs katerkiller

Gemini vs katerkiller

Gemini throws Kater Killer into the CPZ

Tornado threw Kater Killer off its top and proceeded to shove it around the arena when it attempted to self right, putting Kater Killer back on its tracks near Dead Metal's CPZ. After being righted, Kater Killer's weapon was stuck in the fired position. Tornado shoved Kater Killer into the wall before sending it into Shunt's CPZ. Shunt axed Kater Killer, making a hole in the armour whilst lifting it with its scoop. Kater Killer was then pushed onto the edge of the CPZ where one half of Gemini came in and tossed it over again.

"There's part of the twins there, Gemini. A little nudge, and a great attack as well from the pneumatically powered flipper!"
— Jonathan Pearce
Tornado vs shunt

Tornado Kater Killer pit

Tornado ends up in the Pit of Oblivion

At the same time, the other twin flipped Tornado over. Sir Killalot attacked Kater Killer and held it over the flame pit, while Tornado pushed Shunt around the arena. After Sir Killalot had put Kater Killer down, Tornado slammed it into a arena wall knocking the tail off. Gemini had flipped Tornado again, and while Dead Metal was sawing Kater Killer, Tornado suddenly lost control and drove in the pit of oblivion at the end of the bout, Team Kater Killer celebrated, but they didn't realise that Kater Killer had been immobilised for long enough to be eliminated.

"Oh, Tornado's in the pit! They think they're still in, Kater Killer; I don't think they are - I think they were immobilised a long time ago. I think it's Kater Killer that have gone here, despite their celebrations."
— Jonathan Pearce

Despite cease being called, Dead Metal then proceeded to push Kater Killer into the pit.

Qualified: Gemini & Tornado

Berserk 2 (24) vs Inverterbrat vs The CreatureEdit

Berzerk 2 vs the creature

The Creature is lifted by Berserk 2

Inverterbrat immediately drove head-on into The Creature lifted it up. Inverterbrat charged at The Creature again, lifting it but the weapon suddenly malfunctioned and got stuck pointing downwards into the the arena floor, keeping the wheels up in the air and beaching the robot.

"Inverterbrat already causing damage onto The Creature. The Twn Trwn team of last time around showing similar lack of mobility, really."
— Jonathan Pearce
Berserk 2 vs inverterbrat

Berserk 2 is scarred by the bludgeoner of Inverterbrat

Berzerk 2 vs invertabrat

Berserk 2 axes Invertabrat

Berserk 2 had reversed into the two of them to flip The Creature at the same time of Inverterbrat's second attack. After a while, Refbot nudged Berserk 2 away from The Creature and then separated The Creature and Inverterbrat. The Creature drove away whilst Inverterbrat just stayed in the spot as its wheels couldn't reach the floor. Berserk 2 then started to reverse towards The Creature before pushing it away and attempting to flip it over, although it could toss into the air. Inverterbrat still couldn't move its lifter, but its wheels and bludgeoner were spinning madly, trying to show that was alive.

"Look at Inverterbrat! I think they're stuck on the arena floor, I think they've pinned themselves down, there, they have!"
— Jonathan Pearce
Invertabrat demise

Inverterbrat on the flame pit

Invertabrat pit

Invertabrat is pitted

Berserk 2 came in to axe Inverterbrat's rear, missing the first time and getting knocked away and damaged by the still active bludgeoner. Berserk 2 changed tactic and attacked the front of Inverterbrat, hammering the immobile robot eight times before Shunt pushed Inverterbrat towards the flame pit, missing however as Inverterbrat ended up by the arena wall. Dead Metal pushed Inverterbrat in a wall grinder whilst Berserk 2 lifted the Creature up again. Dead Metal pulled Inverterbrat away from the wall with his pincers at that point and started sawing into the bludgeoner and Shunt axed in between the wheels of Inverterbrat. Sir Killalot came in crumple the front of Inverterbrat, spinning it around and hitting The Creature, and holding Inverterbrat over the flame pit for a few seconds before finishing it off and pitting Inverterbrat.

"Inverterbrat left totally spineless and is eliminated."
— Craig Charles

Qualified: Berserk 2 & The Creature


Gemini (8) vs The CreatureEdit

Gemini vs the creature

The Creature is flipped by Gemini

The Creature shell

The Creature loses its shell

Activate was called and Gemini split immediately, one half one way, the other the other. The half of the clusterbot nearest to the CPZ flung The Creature over. The Creature fell back onto its wheels but lost the front of the decorative shell. The other twin came in and tossed The Creature towards the arena wall.

"The Creatures goes naked! Ho-ho! Sheds its skin."
— Jonathan Pearce
The creature vs gemini

Gemini throw The Creature against the side wall

Gemini vs The Creature

Gemini double-teams The Creature

Working together, both halves flipped The Creature, making it balance on one wheel. A smaller flip from one twin made room for both flippers under the wheel and the other twin came in to work with its sibling, and with a combined attack they flipped The Creature over the wall, almost hitting a camera, by flipping the lifting forks.

"Well it's never all over until the fat lady sings, and the fat creature is singing now. Out of the arena, look at that - both of them flipping it up and over. Tremendous attack from the Gemini! Look at that. Oh, it nearly hit our camera! Watch out, Gemini; they're expensive!"
— Jonathan Pearce

Gemini had become the second robot to flip another out of the arena, after Chaos 2.

"Well, The Creature dispatched to the Black Lagoon"
— Craig Charles

Winner: Gemini

Berserk 2 (24) vs TornadoEdit

Berzerk 2 vs tornado and dead metal

Tornado slams Berserk 2 into the clutches of Dead Metal

Tornado started by getting Berserk 2 side on before pushing it around and into the wall. Berserk 2 bounced off and hit Refbot before turning so it could axe Tornado. Tornado dodged the axe and slammed into the other side of Berserk 2, pushing it near Shunt's CPZ. Berserk 2 had activated the forklift but it failed and Tornado pushed it into Dead Metal.

"Berserk 2's going to have to go something here, I think, to beat Tornado."
— Jonathan Pearce

Berzerk 2 vs sir killalot

Sir Killalot crumples Berserk 2

As Dead Metal sunk his saw into Berserk 2, Tornado rammed the trapped robot. After Berserk 2 was freed from the house robot, Tornado immediately pushed it across the arena and into the side wall again, before ramming it several times.

"And Berserk 2, stuck on the arena wall, I think is in real trouble here. Splendid display by Tornado."
— Jonathan Pearce
Berserk2 HeatF

Berserk 2 is put on the flame pit

Sir Killalot pits Berserk 2

After constant ramming from Tornado, Berserk 2 stopped working and Shunt and Sir Killalot moved in for the kill. Sir Killalot made a nasty gash in the side of Berserk 2 before picking it and placing it over the flame pit. Sir Killalot then drove across the arena, dropping Berserk 2 into the pit on its side.

Winner: Tornado


Gemini (8) vs TornadoEdit

Tornado vs gemini w refbot

Tornado rams Gemini into Refbot, shunting both robots towards the side wall

Gemini immobilised

Tornado rams Gemini into the spike

Gemini had a slow start in this battle compared to Tornado. One half of Gemini drove over to Tornado but Tornado drove towards the other half causing it to do a wheelie. Tornado attacked one half of Gemini whilst the other half drove at the side of Tornado. The first twin managed to flip Tornado up but not over before Tornado slammed that twin into Refbot, the arena wall and then, a wall spike.

"Tornado, though, on the drive, slams one of the twins against the arena wall."
— Jonathan Pearce
Gemini vs tornado

Gemini flips Tornado

Gemini helping hand

One Gemini twin helps the other

That twin moved away only to be slammed in the spike again before trying to drive away. Tornado slammed it into the spike and immobilised the twin. The other Gemini flipped Tornado after it had drove at the twin a couple of times before trying to revive the immobilised twin, flipping it and then lifting it only for it to stay dead.

"And the twins helping each other out there as well. Trying to breathe life into its twin sister, there, but is it too late?"
— Jonathan Pearce
Gemini vstornado

The active Gemini twin flips and immobilises Tornado

Tornado was then flipped twice, the first time causing Tornado to go in circles and the second time knocking a drive chain fell off, immobilising it. It did not matter however, as one half of the Gemini clusterbot had been immobilised for long enough.

"The rules say that a cluster robot, a robot of two or more parts, after it's separated, if one of those parts breaks down for more than thirty seconds and is immobilised for more than thirty seconds...'cos it's only one robot, then it's out! So the winner is Tornado!"
— Craig Charles explains why Tornado won

Heat Winner: Tornado

"I've heard a few wolf whistles and a good many phwoars, 'cause it's only good-looking robots, on Robot Wars!"
— Craig Charles' sign-off



The barrels tumble


Pussycat was unable to get the right way up after adding two supporting spikes at the back


Shunt defeats Razer

During the Fourth Wars, alongside the main competition, a Pinball Warrior Tournament and Sumo Basho Competition were also held. Unlike the similar competitions of the Third Wars, these trials featured successful qualifiers for Series 4. In between the first and second rounds of each heat, a Pinball run took place, and two sumo attempts took place in between Round 2 and the Heat Final in each of the first eight heats. For Heat F, the Pinball featured Attila the Drum and the Sumo featured Pussycat and Razer.

Pinball Warrior Tournament - Attila the DrumEdit

Score: 40 points

Sumo BashoEdit

  • Pussycat - 10.60 seconds
  • Razer - 4.87 seconds

Trivia Edit

  • By the pattern of seeds, this heat should have taken place in place of Heat M. It is unknown whether the seeds were deliberately swapped, or the episodes were shot as depicted and simply broadcast in different order.
    • Coincidentally, this would also be the first of two times Tornado was part of a heat that swapped airing order. as it would later be apart of Heat E in the Seventh Wars which was actually Heat A in chronological order.
    • Despite the swapping of Heats, Gemini did eventually appear in Heat M, albeit in the Pinball.
  • Tornado is the only newcomer to ever win a heat in which the winning robot was the only newcomer.
  • Heat F saw the first clusterbot, Gemini, in Robot Wars.
  • It also saw the third Out of the Arena ever, when Gemini flipped out The Creature.
    • This was the first Out of the Arena not performed by Chaos 2.
  • Tornado fought Inverterbrat in the Robot Rumble 2000, which leaves The Creature as the only robot in this heat to never battle Tornado as it did not appear again after this heat.
  • Heat C of Series 6 would be the next heat where a newcomer made it to the semi-finals.
  • Kater Killer's tail fell off during its first round melee and it would later be attached onto Sir Killalot for the remainder of the series.
