But yeah, I think that Anti-Spiral's arrogance is probably going to be the end of him here, because of his tendency to match the opponent to fight on an equal playing field. If he took the form of a galaxy-sized mech he would win this. All personality arguments indicate that he won't. Lelouch beats him in a straight fight due to Anti-Spiral's self-imposed constraints, and he also has a direct counter to Anti-Spiral's trump card, the alternate dimension prison.
Arguments like "AS just rofldestroys him" don't really help either.
