Batman is a pretty good detective, but he won’t be able to defeat Sonic. Sonic’s speed is just too great and he’s not bad at hand to hand either. Batman will need to call on the power of his GL Power Ring, but it won’t be enough. Sonic can harness the powers of the 7 Chaos Emeralds, which gives him unimaginable power. As Super Sonic; Sonic can endure any attack that Batman throws at him and then he will eventually land enough blows to take Batman down. Sonic wins.
