The Grand Apple - Round 2!

I dunno, underdog usually implies something like an unintentional oversight of a really hella awesome character, so I'd say that Eximo, because that was his schtick and because he won the first battle, has gotten the attention a vacuum can handle, and Annaliese isn't really an underdog and more just not very good at what she does.

If I were judging I'd pick either Sunset or Spender, probably Spender because I was in EC and hnnng Sayu was so good.
