Rollback is an alien free for anyone to use.
Rollback's abilities include:
- Chronological Rollback
- Rollback can produce a "Rollback Field" from the eyes on his head and hands. When he touches something with a Rollback Field active around his hands, he can "roll back" the object through time, returning it to an earlier state of existence, such as turning a brick back into clay or reverting an Omnitrix user to human form.
- When he creates a Rollback Field from the eyes on his head, he can apply these effects to himself, which allows him to heal his own injuries and restore his energy.
- Enhanced Durability
Rollback is a 5-foot teal humanoid with dark green and silver armor. He has three fingers on each hand and boot-like feet, and three horns mounted on the top of his head. He has four eyes; two on his head and one on each hand, with the ones on his hands seeming to consist solely of the iris and the pupil. The Omnitrix symbol is in the middle of an "R" marking on the right side of his chest.
Rollback's abilities will not work on any object larger than your average office building. In addition, if he rolls himself back too far, he will automatically detransform.
- Rollback's primary ability was inspired by Wikia's Rollback function.
