Kat's already coming, Raiden is the representative for MGS so you won't get Snake, and get the hell over this "real Dante" crap.
As for the others, I dunno. As far as Cloud/Sephiroth goes, I have the feeling that if a FF representative were possible, they would've done it. I suspect there's a good reason why they're not there. Also, I bet you good money it'd be someone from FF13 (or even the new 14, for advertisement purposes) instead of 7. --- White 2 FC: 0476-5597-5681 White FC: 1764-8367-1938. I love Legendary Pokemon!
