The Fight to the Finish was the event at the end of the show featuring the show's two winners (three in the Season 1 final) that had managed to defeat their opposition in the trials beforehand.
It features a small elevated arena with gates that drop after 1 minute and is surrounded by dull spikes and torches. Robots enter the arena via a ramp on their side, which is then raised once both robots are inside the arena. From there, robots are able to push and attack their opponent with drive power and/or weapons and for some, this allowed robots to pin the opponent against the walls until they dropped, allowing them to score a quick but rather uneventful win.
In Season 1, the platform was a 16 x 16 square until it was enlarged to a 25 x 25 square in Season 2-3. And a new rule was enforced where a robot could not pin another on the wall for more than 15 seconds. As seen in the battle between Zero and The Killa Gorilla.
