Marcus Fenix look is too exaggerated for its own good.
OTOH Master Chief is quite iconic (but quite far behind the most iconic ones) thanks to the huge success of Halo and despite a big hurdle, that they designed him as a faceless hero to ease player's identification. You can't have both things, actually, and in an FPS identification is more important than an iconic character, while in third person games, be them 2D, isometric 3D or perspective 3D, an iconic character is a lot more important.
