Key: SSJMatt2
Character: Mataos
Skill(or transformation): Super Saiyan
How well do you know the source material?(obviously not relevant if it's a transformation):
Reasoning: My reasoning is not just for this situation, but situations before it. Where either his own friends or friends of theirs have come up dead in this city of Jerobeom and each time, he's come up short. This app isn't because someone else is dying, it's more due to his own uselessness when it counts, as every time he really does come up short. Whether it is one of the Demonesses, Ridley, or even his own allies like Yoshida and it's always someone else that pulls through. Whether or not that the other bad guy is defeated, Matao barely contributes. And one of these days if he cannot transform, he will die and achieve nothing. The fact that Hayden lost to Karitori and Julis died, cements that feeling.

What is the moment: The moment comes from when Mataos was just pretty much slaughtered by Ridley due to her unnatural speed and everything she has. (Like she has a lot of speed.) he feels the need to achieve the transformation, whatever the results are between Hayden and Karitori, his current fight has become a lot more personal, because if he can't become strong, like how Ridley is taunting him that golden hair means strong, then he won't be able to protect those he actually cares about-or achieve any sort of freedom in this hellscape. He's no longer fighting for himself anymore.
