NOTE: This hero pack requires a copy of Marvel United: Base Game (Classic or X-Men)
This is a Kickstarter Exclusive and can only be found on the Promo Box

Boom-Boom is a true firecracker. Her ability to generate bombs of pure energy can cause a meltdown in her Location, taking an enemy down a peg or two. But more strategically, she’s able to plant Bomb tokens around, which will only detonate at the start of the next Villain turn, dealing 1 damage to everything else there. Hopefully that gives the others enough time to get out of there!
