When Jean Grey is introduced in X-Men #1 all the way back in late 1963,she asks herself what kind of person she is going to be. The answer to that question doesn't come to her immediately, yet it is exact that from her relatively one-dimensional origins eventually sprang a complex personality full of nuance (a slight variation in meaning, tone, expression) and empathy (sensitivity to another's feelings as if they were one's own) that has only grown more consuming as time has gone on. From the Phoenix Saga to X-Factor to Inferno to the X-Cutioner’s to Onslaught to unusual X-Men to Phoenix: Resurrection and countless alternate realities in between, and Jean Grey has truly been beyond and back.
