Hugo was Professor Paradox's partner who helped him with the time-traveling experiment during the 1950s.
He only appeared in the Ben 10: Alien Force episode Paradox, as a confused time-accelerating creature who ages everything he touches. Ben stops Hugo by forcing Paradox to take him back in time where he made sure that the accident that happened to Hugo didn't happen, nullifying his monstrous existence. Back in the present time, Ben, Gwen and Kevin meet an old Hugo whom Paradox brought to travel in time.
