Body Double

Body Double is the ability to make one or more copies of the individual itself.

Ifrit's Version
Ifrit can create a large amount of Body Doubles in the double digits, but they are all fragile copies that are easily destroyed.

Souei's Verison
Souei can create up to five Body Doubles who can be fully consciously controlled by Souei regardless of the distances, but they only have 1/10th of the power of the original.

Rimuru's Version
Rimuru can create one copy which he can only control completely within a certain distance, however the Body Double can have its appearance further changed and has no real limit to its power as depending on how many magicules Rimuru endows it with, its power can be very close to the original Rimuru. If it's close enough, Rimuru can even use Unique Skills through it.

Appearance
The clone commonly is identical to their creator, although if the original wants to change their appearance they will automatically transform.

Depending on how the master's ideas for the new form of the clone, it can transform into a completely new being. For example, when Rimuru makes his clone to be more masculine and then try to adopt an appearance similar to a grown-up Shizue.

Another method for the change its appearance is that a spirit inhabits the clone.

Limitations
The clone doesn't have a soul, therefore a mind for think by itself is missing. It can't act on its own, so it depends completely on the original's directions for doing any actions.

The clones can't use Ultimate Skills, unless the original have the ability to pass its mind and soul to the clone to make It his/her new "body," or that the skill hse its own mind as King Rafael.
