I see no reason to limit it to one character per game.
-Dr Nefarious from Ratchet & Clank
-Captain Qwark, also from R&C
-Crash Bandicoot (He was a Sony character once!)
-Spyro (same as above)
-Athena from God of War
-Cloud and Sephiroth from FF7 (not a Sony game, but a beloved PlayStation game)
-Solid Snake for the same reason (If Nintendo can have him, Sony can too)
