I never actually liked the blue version of the character - too literal, but I understand how that could work for comic audiences. I always thought the stronger thematic element related to mutants was a man that was so large and agile that he seemed like an evolutionary throwback at the same time as being more highly evolved in terms of intelligence.
Anyway, now that I think about it, I do like the concept. I like the Dr. Jekyll/Mr. Hyde concept, even though I still think the non-furry, super intelligent version is more interesting.
