- Space-Time Lock/Seal
User exists outside of time and space and as such are immune to just about anything that would affect or harm them: if time should stop then the user would not be affected. If reality would change, the user would remember both the previous and have knowledge of differences from the old to the new. If the area around the user explodes or the planet which they are on vanish or does not exist any more the user is not affected since they do not exist inside space.

- If the time change happens to change the event in which the user was granted the ability to exist outside time and space (i.e. Omnipresential Attack), then the user may not be immune to the time changes in question.
- Some users still feel temporal changes, even if they are unaffected by them. Such as feeling subjective centuries pass while time is being accelerated but not aging.
- User may be trapped outside of space-time, unable to re-enter it.
- In limited situations, though they may be immune to changes in time/time stream, they may not be fully aware of the change/changes that have accord, this is sometimes due to their level of control or knowledge of their power or in what series/movie etc. the power is being used in.
- Becoming immortal via this method does not negate pain.
- May vary depending on the nature of space-time.
- Power may not work in regions (e.g. another universe) where space-time functions differently.
- User may be anchored to space-time, even if not immersed in it.
- May only exist outside of physical space-time; may still exist within metaphysical space-time.
- If the user moves in and out of space-time, it may be possible to bind them.
