What superpower would you choose? Most classical superpowers are awesome for combat, but not all that practical in day-to-day activities. Super strength? Guess who’s going to get asked to help everyone move. Fireballs–handy in limited context, maybe, but modern life doesn’t require a lot of fire-lighting on a day to day basis. Metal claws–wouldn’t need to hold pocket knives but you could never get through airport security.
For my everyday life, I would definitely pick the power of Jamie Madsen, aka Multiple Man. Jamie has the ability to create perfect duplicates of himself, each of which is intelligent and has free will. There’s some limit to the amount of how much he can split, but the limit is quite high–something like 50 when he was in X-Factor and more as he masters his power.
