I won't use Rick Sanchez, mostly cause somebody else is using him for HIS Infinity Stones royale and I agree not to use him.

So far the list is the following (and I'll list the Gems in the order Thanos got them, because that was a detial that I've missed):

Power Stone - He-Man

Space Stone - ?

Reality Stone - Aku

Soul Stone - Soul (Soul Eater)

Time Stone - Time Baby

Mind - Megamind
