Season 3.0The KillDozer's first ever opponent was Jaws of Death. The KillDozer lost to a judge's decision 29-16 and was eliminated.
KillDozer first fight was against Timber Wolf. KillDozer tried to push its rear spike into Timber Wolf, but it was too high up. Timberwolf got around Killdozer's side for one good hit, but then had a spontaneous failure and died, and was rammed full of dents on the spikes by the slow, strong KillDozer. KillDozer got the KO and moved on.
KillDozer then went up against Team Cool Robots' Dreadnought. Dreadnought's double-disc vertical spinner put a lot of dents into KillDozer, mostly on the plow blade, but Dreadnought kept having to retreat to spin up. Killdozer looked to be on the offensive, despite the damage. however, the big steel plow blade eventually gave way to the repeated hits and was torn apart and thrown into the air, piece by piece (one piece bounced might have even bounced off the ceiling). KillDozer managed to get one good hit, and Dreadnought's weapon was releasing some smoke. It had a backup weapon, and as the match ended Dreadnought slipped its rear wedge under the battered Killdozer for a push, cementing a 31-14 decision for itself. The KillDozer was out.
