Previously on "Dark Legacy"

Goten Black: "Burst open! and mix!!"

Zamasu: (looks up with a sinister smile) "Excellent!"

F. Trunks: (rubs his eyes and looks up at the sky) "What is that!?"

Goku: "Huh?" (weakly looks up, his eyes widen) "that's...!"

Goten Black stares at the ball calmly in Super Saiyan until his head snapped and he began to breath heavily. He clenches his fist as he's heavy breathing increased, but so did his size as his muscle began to grow, and so did he's body, his clothes began to slowly get turned apart and hair began to appear all over his body. Goten Black started to change into one of the Saiyan's transformations when they have a tail, a Great Ape, but with no moon he created an artificial one that he found out his grandpa created.

Trunks: "He-He's changing"

Goku: "Trunks! destroy the white orb!"

Trunks: "Ri-Right!"

Trunks charges up a ki blast to fire at the artificial moon, but Zamasu appears in his way and attacks before Trunks could fire his ki blast.

Zamasu: "Do not disturb him!!"

Zamasy appears a halo behind him and fires multiple red ki blast at Trunks, who gets hit by all of them and forced out of Super Saiyan 3. Goku tries to stand up, but Zamasu appears above him and his feet onto Goku's back, which in turn forces the Saiyan from earth to remain on the ground.

Zamasu: "Oh no no no don't look away Son Goku" (kneels down and grabs Goku's head and face, forcing him to watch as Goten Black turns into a Great Ape that started to slowly glow golden) "Watch as your son unlocks something you Saiyan's never truly committed to achieving, a level beyond that of your supposed last Saiyan form, that repulsive Super Saiyan 3"

Goten Black in Great Ape form roars as the same golden aura that surrounded a Saiyan in Super Saiyan began to on Goten Black, his brown fur changed to golden and the top of his head grew spiky a hair style that was similar to his SSJ 1 hairstyle.

Great Ape: "GGGRRRRRRR"

The Ape gritted his teeth, it look to be concentrating and angry with how red his eyes were. Goten Black clenched his giant fist and let out a powerful roar that shook everything around him. His aura flared with sparks of electricity now surrounding him, it is as if this Golden Great Ape form just went from Super Saiyan 1 to Super Saiyan 2.

"RRRROOOOOOOAAAAAAAAAARRRRR"

Goku: "Tha-That form"

Zamasu: "Do not worry, unlike you fools who take their time mastering this form, Goten will have full control of it in seconds" (chuckles) "Saiyan legends for told of this state, saying it is a gateway for even greater power that Saiyan could reach"

Goku: "Gate...way?"

Zamasu: "Why yes, this form is powrful, but it is only a gateway towards his real power" (stares determinedly at Golden Great Ape Goten Black) "a saiyan's true primal form!"

"ROOOOOOOOOOOOOOOAAAAAAAAAAAAR"

Goten Black, now in his new gained Golden Great Ape form roars at the sky, the aura surrounding him flared like a rising fire, the top of his head resembled the same hairstyle he would have when in Super Saiyan transformation, and blue sparks of electricity coursed around him. Zamasu, who still forced Goku to watch, was looking at Goten Black with a proud smiles while Goku on the other hand was getting nervous. The power of this Golden Great Ape was great, not as strong as when he's in super Saiyan blue, but it's still powerful.
