Character from Invincible by Robert Kirkman
Two identical supervillain scientists — one is the original and one is the clone, and neither knows which is which, and the argument never ends.
The Mauler Twins are simultaneously brilliant and absurd. They're capable of cloning technology, consciousness transfer, and feats of engineering that rival anything on Earth — and they spend half their time arguing about which one of them is the original and which is the copy. The argument is irresolvable because the cloning process is perfect: neither twin can prove primacy. This existential crisis plays out as petty bickering between two enormous, blue, genius-level criminals.
Two massive, identical blue-skinned humanoids with oversized builds, bald heads, and brutish features that belie their genius-level intellects. Wear matching dark jumpsuits. Physically indistinguishable from each other, which is the entire problem.
