Super Saiyan Esmeralda

What is Esmeralda?
Super Saiyen Esmeralda is a power level that can only be reached by those who have permanently been fused (i.e. Goku Black, or Elder Supreme Kai of the 7th). This is because these fused beings have the mortal power of two different beings, unless they are a deity (Kai, Destroyer, etc,), in that case they would have the power of multiple divine being at their disposal.

Look?
Super Saiyen Esmeralda gives its owner a set of either dark green hair, or a bright almost highlighter green hair. The brighter it is the stronger the wielder.
