Super Saiyan - Full Potential

Super Saiyan - Full Potential is the final and most powerful form of Super Saiyan that is attainable by a non-godly Super Saiyan.

Prototype
The Super Saiyan - Full Potential form went through numerous changes when being created.

Originally it appeared identical to base form and was referred to as Super Saiyan Final, with Olant being called "Ultimate Olant" - however due to being too similar to Saiyan beyond God, this version was scrapped.

The second version was identical to Golden Super Saiyan, but with bright white fur instead of gold fur. This version was referred to as Everlasting Super Saiyan.

Appearance origin
The form having glowing white hair and red pupils is based off of how the Super Saiyan form originally appeared in the manga: where it gave the user white hair instead of blonde hair, and red pupils instead of green ones.
