Without any direct knowledge, what exactly Kolruu is can be confusing. A Yondard? An Autyon? Something one may call an Abberant?

In reality, Kolruu is unique amongst other Yondards, but 'unique' may be applying undue remarkability depending on who you ask. Whatever traits that may make him similar to others as a general species, he is best described as a vessel.

Even more rarer and more powerful than what some deem Aberants, Beyondards are not so much a 'transformation' moreso a 'rebirth'. However, it comes at the cost of one's very being. But in a dire situation, one simply made another 'self' to reside in.
