Full-Powered Super Saiyan 4 (SSJJ)

Full-Powered Super Saiyan 4 is an enhanced state of Super Saiyan 4 after receiving Saiya Power (or an individual(s) transferring all but the energy required to live on).

Overview
"Even after I've just reached Super Saiyan 4 - I was still able to take it to a new level. I think I'll call this form Full-Powered Super Saiyan 4"

- Goku upon taking on the state in Great Ape Baby!?

This state can be achieved by absorbing an extreme amount of extra Saiya Power or receiving almost all the energy for an individual(s) except for the energy they need to live on. It possesses power greater than the ordinary Super Saiyan 4. In the Fanga; it give the user the ability to absorb a large pool of energy as Goku did with Baby's Revenge Death Ball Final or Vegito absorbing a Spirit Orb. Normally the form is temporary, but after Goku and Vegeta defused from Vegito; Goku was able to enter the form freely.

Usage and Power
While in this form; the user possesses a double aura and is able to magnify the power of the user as Goku was able to overwhelm Golden Great Ape Baby while Vegito was able to overpower Super 17 even after he absorbed Android 16. Vegito's inner aura is mixture of Majuub's aura, and Goten and Trunks' base form aura; and as such as; Vegito's double aura consists of a transparent pink aura with the standard yellow aura while Goku's version possesses the radiance of the Super Saiyan 2 aura and radiance of the Super Saiyan 4 aura.

Ultra-Powered Super Saiyan 4
Goku achieved this state after absorbing Baby's Revenge Death Ball Final; allowing him to knock down Baby with a single punch before the villain's tail was severed. Goku was unable to retain this form like the Full-Powered Super Saiyan 4 state, but was able to retain half the power the state offered him.

Vegito briefly took on this state before separating back into Goku and Vegeta.

Mastery of Super Saiyan
Mastered Super Saiyan 4 is a result of Saiyan calming his mind while transformed; Goku was able to apply Mastery of Super Saiyan to this form and gained the ability to utilize Kaio-ken along with Master Super Saiyan 4 and even able to use Spirit Bomb.
