After high school, Robbie Baldwin began working under Dr. Benson at his Hammond Labs. An accident occurred while the scientists were investigating an energy source originating from another dimension. Numerous energy bubbles shot out of the dimension and started to engulf Niels and Robbie, granting them both kinetic superpowers. Robbie Baldwin decided to use his newfound powers to become the superhero Speedball.
Penance and P-Cat
After the tragic events of Stamford, Connecticut, Robbie Baldwin transformed from the happy-go-lucky Speedball to the regretful Penance. Penance explained to Squirrel Girl that Niels was now P-Cat, the Penitent Puss.
When Speedball decided to join the staff of the Avengers Academy, he and Niels moved into the Infinite Avengers Mansion. During the attack of Greithoth and Skirn, Niels survived the destruction of Infinite Avengers Mansion and was found bouncing around Lincoln Park by Quicksilver.
Niels eventually ended up in the custody of S.H.I.E.L.D., who kept him in captivity and began experimenting on him to study his powers. With the experimentations having ended, Niels was scheduled to be euthanized because he was seen as too dangerous. However, Jim Hammond took pity on him for being different and decided to save Niels' life by adopting him.
Powers and Abilities
Similar to Speedball, Niels has kinetic powers due to accidental exposure to extra-dimensional energy during a lab experiment. His powers include:
- Kinetic Energy Field: Niels has the super ability to create a kinetic field of unknown energy around himself, which absorbed all kinetic energy directed against him. 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. When transformed he is surrounded by a display of multi-colored bubbles.
