I say sweet tooth because any one who ever owned any play station knows who he is especially the ice cream truck. For all those who say you can't advertise sweet tooth for kids, go look up the old ps1 commercials. That also goes for those who say Sony doesn't use mascots or have one true face, but apparently they had crash, Laura, and sweet tooth be in most commercials.
Kratos, but I personally think that when Ratchet is announced, it should be him seeing as how he's had the most games out of all these characters and is practically the Mario of Sony exclusives. That's just me though.
