Mr Fantastic

Mr Fantastic, also known as Reid Richards, is the leader of the Fantastic Four and the resident super-genius as well as the boyfriend (and later husband) of Susan Storm - despite his vast intelligence Reid suffers from a bit of a "mad scientist" syndrome and often gets himself and others in trouble with his experiments.. however he is much more responsible than Johnny Storm (aka the Human Torch) and would never harm anyone on purpose - through no true fault of his own Mr Fantastic has become bitter enemies with the vain and power-hungry Dr Doom,one of the few men alive who may be smarter than Reid.

Of course no matter how smart Doom is he is always defeated by Reid Richards with help from his friends, the Fantastic Four.
