Fighting Broly, your power wasn't even able to be compared to his, after all, he IS a Saiyan that was raised on Planet Vampa, a frontier planet (after he and his father were exiled there due to a jealous/paranoid King Vegeta III who repudiated the fact that Broly had greater potential than his son, Prince Vegeta, having a power level over 10,000 that was growing each day). But you, were a Saiyan as well, a Saiyain that was secretly more powerful than even the Legendary Super-Saiyan, calling you a mix of 2 legends in 1 body: a Burnt Super-Saiyan and a Dark-Light Saiyan.

To explain, if you felt weak and then felt angry, vengeful, and yet hopeful, your hair would turn a flame yellow that would burn like a flame, yet not burning your hair, while giving you pure yellow-glowing eyes. However, you also had 2 Alter-Egos, your Dark Persona, and Light Persona, each of your egos both powerful enough. And now, fighting Broly started to break your hope of actually beating him; as Goku and Vegeta were doing their best to help you fight Broly (Goku in his SSJB form, and Vegeta in his Blue Evolved Form), Whis, Freiza, and Bulma were watching you take on blow after blow, you finally snap, and turned into a form more powerful than any other. And soon you went, for your 1st time, into your Burnt Super Saiyan form, and went berserk on Broly, hitting him with powerful attacks that he couldn't take.

So, Goku and Vegeta learned the Fusion Dance and came back as the fusion, Gogeta, as you were about to finish Broly off, Goegta came in & soon, a battle with you and him came to be, with his winning in the end, though you gave him a tough fight since he only hit you with a Limit Ultra Kamehameha that was able to only KO you. As Freiza left the planet, you were then teleported to Planet Vampa, due to the Dragon Balls, and were soon standing face to face with Broly, who had recently calmed down with Cheelai, and Lemo, by his side. As he then noticed you, Goku then teleported next to you and got you up.
