Both have been suggested. The Tiger has been suggested quite a bit...and I don't think it was as iconic as Crash/Spyro/Gex/Sonic/Mario/Croc/etc. I wouldn't mind if they added him though.
The alien has been mentioned a couple times before, but I think definitely deserves a spot. It comes from a very unique game, but it wasn't that popular (shamefully). --- PSN: MoHSalim http://www.youtube.com/m0hsalim
Ya mean Crypto? Nightstryk3r619 was going to do a moveset for him. But eeh, there are characters more deserving of the spot, as much as I like Crypto. --- "Pray not to have easier lives, but pray to be stronger men."- President John F. Kennedy. GT: Dsurion21
