Double-Double is a superhero affiliated with the Legion of Vigilance.
- Duplication: Can duplicate himself, his doppelgangers either mimicking his movements, or having their own, upon the brain's choice. This power is what Double-Double is known for. The power has side-effects, if too far away, the doppelgangers cannot regroup back into the true body,and if left out too long, develop a personality of their own. When these "old" doppelgangers regroup, Double-Double may have major mood swings, changing by the seconds.
- Mind Switch: This power allows the true Double-Double's mind to temporarily switch to that of a Doppelganger's rendering the Doppelganger into the true body for the limited amount of time, tricking any enemy.
