Reed Richards (Mr. Fantastic)

Ever tried stretching your understanding of quantum physics while also stretching your limbs across town? That's a day in the life for Reed Richards. The guy's a walking, talking, sometimes bumbling genius who can debate the ethical implications of time travel while accidentally tangling up in his own elongated limbs. Fans are torn between loving his brain and face-palming at his lack of common sense in everyday situations. It's like cheering for the smartest klutz in the superhero universe.
