Multitude

Adam Dai, better known as Multitude, is a highly-skilled athlete and martial artist with the ability to temporarily create duplicates of himself (although he has never been known to create more than six at one time). Although weaker individually than the other Champions, Multitude poses a significant threat to villains who underestimate him. In battles with powerful opponents, Multitude teams up on them with perfectly coordinated and complementary martial attacks. Against many weaker opponents, Multitude divides and conquerors.
