The GM's are discussing both of the Thor sheets we have been given, but I must remind people of this rule that I did not setup for vanity reasons:

[i]Legacies (NPCs, sidekicks, rogues) fall under the jurisdiction of the hero they are traditionally designed around. If you want to play The Joker, The Batman player has to be okay with it and your information should never contradict what they have written in their CS. This one is malleable, but again—communicate. [/i]

There can be exceptions to this rule if thoroughly explained (see: Gowi's White Tiger, Morden Man's Captain America), but I'm having trouble with thinking it is as thoroughly explained from what we have been given for Thor.
