Mythic Transformations

A transformation that can occur in any species. Mythic transformations take place when you reach ultimate power in your current form. Goku achieves Mythic Transformation in his SSJ1 form and that has made it stronger than Super Saiyan 3.

Mythic Transformations also happened in: Vegeta and Tien Shenhan. Later, Gohan gains this strength and so does Yamcha.

Appearence
It started while Goku was fighting Thorur on Planet Vegeta II, Goku used a kame-hame kick while in Super Saiyan form at the same time blocking Thorur's energy cannon.

Goku's hair started to turn a snowy white and his eyes turned a dark grey and it ended with Goku's hair still in the Super Saiyan form and a golden aura swishing around him.

With Tien, his eyes turn into a shining grey and develops a grey aura going around his body. Also a letter gets formed onto his head while in this mode. It symbolises Myth.

Power
Goku increased his power x40 which is much more powerful than Super Saiyan 3, maybe even 4. It increases a persons power because it unlocks the mythical power inside which is alot because it draws unknown energy from the universe.

Tien gained enough power that he was as strong as an ascended saiyan.

Vegeta gained the same abilities as Goku and first experienced it while in Super Saiyan form aswell. He watched Kakarot (Goku) transform and then he transforms while fighting Goku in the Federal Championships on planet Heigan.

Mythic Gogeta is the strongest being, it states that his power level is over 6,000,000,000 which is the highest in the universe recorded.
