Raja - my favorite character, corny and just generally awesome.
Rika - what's not to love?
Gryz - would prefer a PS/PSII style motovian but I'll take what I can get.
Wren - he's a great powerhouse and so steadfast, ol' reliable.
Demi - not the most powerful but useful and unique.
I was tempted to bring along Seth just because I think he looks like Mario but it wasn't enough to get over the whole super evil entity thing. I've always found Chaz and Rune to be a bit annoying so while they are among the most useful, yeah. Plus, the thought of making Chaz and Rune stay behind together struck me as amusing. It was a toss up between Rika and Kyra, both are great, but the numan won out in the end. Alys, she's great but doesn't quite cut it power-wise.
