Living Eraser

Ant-Man has a rogues gallery full of laughable villains such as the Human Top, Egghead and Porcupine. Here is one of the more bizarre members of his rogue gallery: the Living Eraser.
History
The Living Eraser is from Dimension Z (no connection to Dimension X from TMNT), which occupies the same space as our dimension but in a different universe (lets pretend that makes sense). He was sent to Earth to "erase" several scientists. In reality, he was teleporting them to Dimension Z, where they were held prisioner. Among his victims was Henry Pym, the original Ant-Man. However, Henry secretly smuggled the Wasp with him. As such, she helped free Henry. The duo fought an army of Dimension Z aliens and found their chief sciencist. Eraser killed the alien sciencist to prevent the secret of the techology getting in the hands of humanity. However, Eraser revealed his power came from the gadgets on his palms. As such, the Wasp and Ant-Man stole them and took the sciencist home. The Living Eraser appeared time from time later on and fought foes such as She-Hulk, the Thing and Morbius.
Powers and Abilities
The Living Eraser's powers come from the "atomically printed circuit[s]" on his hands. This allows him to "erase" people. In reality, the "erased" people are being sent to Dimension Z.
