Psychoman+Spider-Man+Rhino

Psycho-Man is a mad scientist, the leader of a technocracy that governed a system of worlds within a Microverse. Facing overpopulation, he determined that it would be easier to cross other dimensions than to travel to other systems. Deciding that Earth would be an ideal target due to its inhabitants vulnerabilities to his unique weaponry, he used scientific means to enter the normal-sized universe, though he was only able to achieve microscopic size in this world and has to resort to a human-sized, armored exoskeleton to interact with anything not on a microscopic scale.

Using a portable device capable of influencing people's emotions, Psycho-Man used a number of human subjects to build a larger-scale version of the machine, one capable of covering the world with its emotion-influencing rays. This effort was thwarted by the Human Torch and The Thing, several members of the Inhumans, and the Black Panther, and Psycho-Man was forced to retreat back to the Microverse. He was subsequently followed by the Human Torch, the Thing, and Mister Fantastic, who were forced to let him go in order to deal with a greater threat back in their own dimension. Psycho-Man later faced the Fantastic Four again, as well as a group called the Micronauts who were native to his home dimension, by which time he claimed to be in exile from his homeworld.
