Classic magic Chuck
in the Khazan arena isn't WALL-E basically completely untouchable for Chucky? I don't see how he can match the little bot's travel speed. to make matters worse, WALL-E has a laser that can hit Chucky (and hurt him badly) at much longer ranges than Chucky can hit WALL-E. isn't Chucky's standard equipment nothing more than a knife? because if that's all he gets in the arena he's completely screwed.
even in a household scenario he's going to have a tough time seriously damaging the little bot... but at least he might get 2 out of 10 with the element of surprise, rudimentary prep, and some weapons.
