Zenithman Milave can be described as, and technically is (metaphysically-speaking), many things. He can be:

1. the result of the fusion of Zenithman Magnystic / Ryan Genesis, Zenithman Lionheart / Daiki Miyabe and Zenithwoman Valor / Hitoko Ebinuma;
2. the result of one Zenith’s soul fragment becoming complete via merger with another 3 Zeniths;
3. a fusion entity who originates from 3 Zeniths giving their powers to a 4th to create an entirely new Zenith;
4. or anything in-between.

Ultimately, however, the best, and most complete, way to describe him, is as follows; Zenithman Milave is a Fusion Zenith with a mind of his own whose birth is the result of a Fusion Zenith’s formation being the catalyst for the transformation of a separate, singular Zenithman’s soul fragment into a fully formed soul/Zenith Warrior. 

This, in turn, means a great many things: Milave inherits both the combined strength, energy signatures, and powers of his components (those being Zenithman Magnystic, Zenithman Lionheart, and Zenithwoman Valor), while also inheriting the personality traits and powers of the Zenith whose soul he was originally a fragment of (that being Ignitious Tharrokarys / Zenithman Ignitious).
