Who is your strongest character?

[Summer]

Ohhh this is a close one.
Clown's speedy, mischievous, and surprisingly a better fighter than Summer (though not Sonny). With all her fancy little lunacies she can induce upon him, and all her fancy little tricks like making him think she's a hallucination, she should be able to run circles around the split spirit.
But then again, Summer also hits like the hand of god itself. One good Lightning Strike will annihilate Clown, given her pretty measly defense. He just needs to actually keep track of her, not get driven mad and do dumb shit, and try and get within melee range, where he just smashes her into a pulp.
Against Sonny, she'd probably fare better, since Sonny's mostly focused on helping allies rather than fighting himself. There's not a whole lot he can do on his own.
So, Clown's probably the strongest of the 2(3?), but not by a whole lot.
