Simons

Simons is Overlord's assistant. He first appeared in the Ben 10: Ultimate Alien episode, Hero Time. He came up with the idea that Captain Nemesis would be the number-1 hero, because Ben was just a 'fad' and would blow over eventually. He also tried to persuade Overlord to not amp up his suit, clearly claiming it would be like suicide and he would regret it for the rest of his life.
