Time Travellers

Heroes who can travel through time - these heroes are often able to amass great power as a result and too have great advantages over their enemies due to advanced technologies/magic and heightened intelligence or warp time so as to restore or create alternate realities (often with themselves as a savior and/or a ruler) and restoring and preserving the space-time continuum.

Not to be confused with Heroes from the past who are heroes who disappeared in the past and later came back to resume their heroics.
