Parallel Existence

Summary
Parallel Existence is the ability to exist in multiple universes and have a shared concious among those parallel versions. Users of this ability exist in many different dimensions and all those versions share the same thought/concious as the original version of said character. Some instances, characters have many copies of themselves across the multiverse and in some cases, may be able to control them if killed in the prime universe

Possible Uses

 * Acausality: Users who exist in every single dimensions are essentially a constant across space and time, meaning that killing the original isn't going to kill off the entity itself. This would qualify for specifically Temporal Constance
 * Immortality: Some users can make themselves completely immortal due to the fact they have alternate iterations of themselves, granting them various forms of immortality that can range from Type 6 (For those who specifically possess other versions of themselves), Type 8 (For beings who can't be killed off due to being reliant on the existence of their alternate selves) or Type 11 (Killing the entity in one universe will only cause them to reincarnate in another universe)

Limitations

 * Should their alternate iterations be killed off, the original entity will be left without any addition forms of concious for the case they are killed in the original universe
 * Attacks or abiliites that are multiversal in scale and range can often effect the entity and their alternate counterparts
 * Some users may not be able to control their alternate selves and they may act fundamentally different from their prime selves
