Powers: Possesses the superhuman ability to leap in a very similar fashion to Toad's power. One is also able to see the genetic structure of those around him.
Bio: Nothing is known about One before he encountered Firestar and The New Warriors.
One is a member of the superhuman evolutionary terrorist group known as Eugenix. The main purpose behind Eugenix seems to be a cleansing of the human race. They sterilize those they deem unfit to carry on the human race, and simply kill those that they believe drain society's resources simply by being alive.
