Speedball, Robbie Baldwin, was created by Tom DeFalco and Steve Ditko as a Marvel Comics New Universe character that never made it to publication.
Appearing in Amazing Spider-Man, he then had his own series, before joining team book New Warriors and knocking around the Marvel Universe, until – guilt ridden at the many civilian deaths at the beginning of Civil War, he became Penance.
Eventually he got over it.
He got his bouncing kinetic powers, in the comics at least, from a laboratory accident where he worked, being exposed to extra-dimensional energy.
But, with Baldwin to appear in the next run of Marvel's Agents Of S.H.I.E.L.D., and their current seeming-love of Inhumans, might it make sense for Baldwin to have gained his powers from Terrigen mists as well?
And if so, as is expected with Scarlet Wtch and Quicksilver, will that move to the comic books as well?
Get in that cocoon, Baldwin!
