Retro has the unique power to control wormholes, opening portals through time without a machine. This mysterious character appeared suddenly in the disaster that destroyed the Time Guardians' time machine. He was discovered unconscious and concealed behind black garb. The General immediately captured and imprisoned him for fear that he is an alien agent. Now, he is the team's only hope to travel back in history. Can he be trusted?
Retro focuses his powers into a weapon called the Black Hole-in-One. A portal opens up in the ground and sucks in all nearby enemies, never to be seen again. Even Retro doesn't know where the portal goes, but he guesses it isn't pleasant.
