Equivalent

There are infinite universes in the multiverse, and so by chance similar characters may appear. Sometimes, characters can remain virtually identical despite appearing in entirely different universes. The term used to describe this phenomenon is equivalent.
Prime equivalent is a term used to describe the original or most prominent equivalent of a character. 
For example, see Laurence (Reverend James) and LDthebadman (LDthebadman & Pavel), two characters from different universes with the same voice and a very similar appearance.
For the timeline version of this term, see variant.

* The first instance of an equivalent being named as an equivalent onscreen is mistakenly referred to as a variant - that being Prince Escalus (equivalent 23).
