except Manhattan has the circle thing (hydrogen atom) on his forehead instead of Triclops’s eye on a block on top of his head.
In case anyone’s wondering what the hydrogen atom means, this is what the internet tells me:
Jon gradually becomes a pawn of the United States government, though the means by which his loyalty is secured are never revealed; he is given the code name ‘Doctor Manhattan’, a reference to the Manhattan Project that, it is hoped, will defeat America’s enemies. He is also provided with a costume which he grudgingly accepts, though he refuses to accept the icon design which is provided for him (this being a stylized orbital model of the atom). Instead, Jon chooses as his emblem a representation of a hydrogen atom, whose simplicity he declares to be something that kindles his respect; accordingly, he painlessly burns the mark into his forehead. This preference for material mechanisms marks the beginning of Jon’s declining humanity, which is progressively mirrored by his gradual shedding of the uniform – by the end of the 1970s, he refuses to wear anything at all except for mandatory public appearances.
