- Both of these grudge matches featured, and were won by, Mortis
- Some consider the circumstances behind the second grudge match harsh on the Mortis team, and during the build-up to the battle, the impression was given that Rob Knight argued for a second run, where as in truth he was made to by the producers, and as a result refused to drive, leaving the controls in the hands of the inexperienced Ben Impey.
- Ironically, in the first grudge match, Mortis lost a track by driving over a spike, but won anyway, the same set of circumstances with which the second grudge match was set up.
- This was also the last on screen appearance of The Sentinel, who was retired after this series
The first grudge dated back to a judges' decision in The First Wars when Recyclopse (the original robot of Team Cassius) controversially defeated Mortis for a place in the Grand Final. The Mortis team believed that they had won, and argued vehemently against the decision, and a lot of people were very surprised, although pleasantly, at the outcome. Rob Knight suggested at the time that a rematch take place.

The second grudge, entitled Judgement Day 2 dated back to the Trial in the series semi final when Mortis sustained damage to one of its tracks but was given a second chance by the production team and gained enough points (with a bit of help from the House Robots) to eliminate Napalm from the championship.
Cassius vs MortisEdit
In the grudge match, Cassius started by driving straight into Dead Metal and was then unable to get underneath Mortis and Mortis did damage with its axe. Cassius then drove into Sergeant Bash but escaped and drove close to the pit, before dipping a wheel over the pit stranding it, but was rescued by Shunt. The track on the right hand side of Mortis had stopped working close to the pit and they were unable to move away.

Cassius charged at Mortis, getting underneath and slamming against the stricken machine. Cassius drove at it again, but missed completely and fell spectacularly into the pit of oblivion. The immobile Mortis was then pushed into the pit by Dead Metal, after being dented in a rare display of damage to the very tough armour of Mortis. Cassius then, used its self-righting arm to try and rescue Mortis from the pit, pushing one track back onto the arena surface, and Mortis hammering wildly with the axe to help but Mortis still couldn't move and cease was called.
- "Sorry, we declared it a dead heat. We've gotta go again."

After the fight ended, the Mortis team tried to have the match restarted, as they felt that that they hadn't won, due to losing a track and Cassius driving into the pit. However, a rematch never took place.
Judgement Day 2Edit
Mortis vs NapalmEdit
Mortis was immediately the stronger robot, getting underneath Napalm with the first charge. Napalm then retaliated with its infamous 'mandibles', in fact a modification of its original chainsaw weapon which Sir Killalot decapitated in its Heat Gauntlet. Mortis then pushed Napalm for a while before attacking it with its own axe, chopping off one of the 'eyes' of Napalm. Mortis attacked again, causing damage to the front, and then the rear of the Dartford machine.
- "Oh Claire! What have you done Claire!"

Napalm bravely pushed back, but, on a charge, the force of its own weapon caused it to overbalance and, as in its earlier Grudge Match, Mortis' opponent fell into the pit by itself. Mortis wasn't finished however and, with an almighty roar from Rob Knight, Mortis attacked Matilda, causing minor damage to the front, and Sir Killalot's breast plate but the House Robots retaliated, Matilda and Sir Killalot teamed up to overturn Mortis, and then Shunt and the Sentinel took over, causing damage to the underside of Mortis. Killalot then picked up Mortis, and grilled it over the flame pit. At the end of the battle, Rob Knight kissed Claire Greenaway as a 'consolation prize'.
