Beast

Evolutions: “X-Men: 1st Series”; “Amazing Adventures #15”; X-Men: The Last Stand; X-men: First Class

Beast’s evolution wasn’t just stylistic, it was genetic as well. An original X-Men character, he started out furless. By the time he appeared in “Amazing Adventures,” he had become the blue furball we've all come to know. Kelsey Grammar modeled himself a little after Beast’s more hardcore look in “Astonishing X-Men 3rd Series,” a script Nicholas Hoult mostly sticks to in First Class.
