After being given kinetic energy based powers in a laboratory accident, Robbie Baldwin became the hero Speedball. He later became a member of the Young Avengers.
Powers and Abilities
- Kinetic Energy Field: Robbie Baldwin's exposure to energy from a dimension of kinetic energy gave him the superhuman ability to create a kinetic field of unknown energy around himself which absorbed all kinetic energy directed against him (what he originally called the "Speedball Effect.") This absorption could vary from resisting the effects of physical objects such as bricks and rocks to resisting that of energy and fire and even explosions. Within his kinetic field it was nearly impossible for him to be hurt, and he instead bounced harmlessly from object to object, with no loss or transference of momentum.
