Editing Robbie Baldwin (section)

===As Speedball===
As a result of the mutagenic effects of irradiation by an unknown form of energy, Robbie Baldwin possesses the superhuman ability to create a kinetic force field of unknown energy, manifested as iridescent bubbles, around himself which absorbs all kinetic energy directed against him and reflects it with even greater force against whatever object with which he is in contact. Hence, if he struck a wall, he would travel at a greater velocity in the opposite direction.

When Speedball uses his superhuman powers, solid force bubbles of residual kinetic field energy appear on his body and, when he bounces, in his wake. While bouncing, he is immune to any kind of harm caused by physical contact. Speedball's power activates automatically when any physical contact occurs above a low level that has not yet been precisely determined. When Speedball's kinetic field activates, his body increases in height and mass (drawn from an extradimensional source); he reverts to his normal size and mass on deactivating the field. Early in his career, the slightest touch, such as snapping his fingers, would turn on this field, but he eventually gained conscious control over it. The field repelled all energy that struck it, especially kinetic energy. As such, bullets, punches, and all other physical attacks bounced off him. A side effect of this, though, was that he, too, would bounce in the opposite direction. Baldwin often used this to his advantage, such as purposely running into a wall in order to gain momentum and thus hit an opponent with twice the force.

While with the Warriors, Baldwin gained far greater control over his powers via a combination of experience in battle and Night Thrasher's mentorship off the battlefield. Whereas previously Baldwin could barely bounce in the direction he wanted, he eventually became more proficient at controlling his leaps and using his powers in various ways, such as to deliver impressive blows, and even to project a stream of [[kinetic energy]] from his bubble field at a distance. He eventually learned to mentally "throw" the bubbles that surrounded his field to use as concussive force attacks. He was able to somewhat deflect [[Siena Blaze]]'s electromagnetic attack that "no one short of the [[Hulk]] could have withstood", as well as resist the omnipath [[Gamesmaster (comics)|Gamesmaster]]'s telepathy, one of the few people in the world to do so.<ref>''New Warriors'' #46.
