Shroud

Shroud is a strange life form brought to the Prime Timeline when the timeline he was from was being undone by a powerful return to the past, and the events that led to create him did not happen in the current timeline. Shroud was a powerful program created by X.A.N.A. in his home timeline to be the backbone of his army, and his most powerful creation. Shroud seems to be perfectly independent, and not directly bound by his master's will, but seems to have his own AI. Now, with no X.A.N.A., Shroud seems to follow Zane across time to aid him in his destruction of history. While the World Savers no longer remember him, he knows all too well who they are.

In combat, Shroud isn't overly complex, but is not to be messed with. He is able to move at speeds almost unseeable by the naked eye. He fights only with swords and daggers, which do not seem to break. The trick to beating Shroud is to outsmart him, as his speed is one of his only weapons. If he has other skills, they are unknown.
