"Black! I will kill you myself!"
"If you want to call it a sin, then I don't care!"
The true nature of this form has yet to be explained officially, but in appearance, this Super Saiyan state has the traits of several other Super Saiyan forms; it primarily resembles a standard Super Saiyan, but with a more intense glow, and has the aura of Super Saiyan Blue, but with most of the outer aura being golden and only the inner part being blue. Future Trunks' irises and pupils are temporarily invisible, similar to the Pseudo Super Saiyan and Legendary Super Saiyan forms, his voice enters a deeper and more sinister tone, and his hair is a mixture between the Super Saiyan 2 and Super Saiyan Second Grade forms, only with an even more golden color. Also when transforming into the form his muscles bulk up similar to Super Saiyan Third Grade before the blue part to his aura appears and his muscles return to normal. When moving around in this form his footsteps cause cracks in the ground. Similar to a Super Saiyan 2, his aura also emits dense, blue lightning.
Usage and power
The power of this form allows Future Trunks to fight both Super Saiyan Rosé Goku Black and the Immortal Future Zamasu and force them on the defensive. He utilizes the form to hold the two off by himself, while Goku and Vegeta travel back to the present in order to find a way to defeat Black and Zamasu. After being defeated and treated by Future Mai, Future Trunks uses this form again to fight the pair, knocking away Future Zamasu while seemingly defeating Goku Black with a relentless assault.
