The time I was fused with my cat and sent into the Dragon Ball world

3 Mortals against a single Devil, Godly Awakening

In 4 streaks of light, myself, Xeno Goku, Xeno Vegeta, and Xeno Trunks fly in at Broly as one force. I notice Goku and Vegeta share a glance, however, and suddenly break off. "Kakarot and I have a plan, buy us time!" Vegeta yells, flying away to do something. I keep my focus on Broly, locked in as I punch him backwards, but he grins with malice and forces me onto the defensive as he rams forward towards me. Catching him mid ram, I'm pushed back as Trunks fires a blast from behind, suddenly flying in with his arm pulled back. Broly smacks me away, causing my vision to blur for a moment, but something is stirring within me. I feel it.
"Broly! I beat you once in another timeline, and I'll do it again!" Trunks shouts in defiance, starting a temporarily equal clash against Broly. It doesn't last long, though, as Trunks is knocked away. At the same time, I sense two energies merge into one. A fighter appears, one I recognise. Gogeta in Limit Breaker Super Saiyan 4. I slowly stand up and force myself to keep going, my vision clearing.
"Broly is too big of a threat for one to fight alone. I can tell you have godly energy, but not enough to manifest more power. Focus on manifesting it, me and Trunks will fight Broly." Gogeta orders, calm and stern as he charges in against Broly, who stops beating on Trunks and looks at Gogeta with curiosity and malice.
"Who are you now...?" Broly asks, excited and curious.
"I am neither Goku nor Vegeta, I am the one who will defeat you, Broly!" Gogeta responds in threat, flying in with a battle cry. The power being thrown around causes me to jump back to avoid being caught in the crossfire. I focus myself, trying to find that God Ki. Powering down to calm myself, I enter the mindscape, where Zoom is staring at something with fascination. A red orb of flame. It's warm and comforting, but he's not sure about it. I walk towards it fearlessly.
"Don't be afraid of it, Zoom. You want to know why you shouldn't be afraid?" I ask, causing Zoom to meow and look at me in curiosity, tilting his head. "Because I am here, and this power is ours to command." I grab the flaming orb, godly heat spreading over my body. The heat spreads to Zoom as well, my body glowing with red light as his fur takes on a godly crimson hue, my hair and eyes doing the same. On the outside, more time has passed than on the inside. Gogeta is pushed back by Broly, who's somehow evolving. He's somehow figured out how to transform into Limit Breaker Super Saiyan 4 without a tail. A pillar of godly fire erupts in the distance. Gogeta defuses, and Broly fires a blast to finish off Goku, Vegeta, and the unconscious Trunks they're protecting. The pillar curves, crashing down in front of the blast faster than the blast can travel. A glowing red hand comes out of the pillar, catching the blast.
"This ends today, Broly." A voice from the pillar says, echoing across the planet. The blast becomes a godly crimson and goes right back towards Broly, who jumps away from it as it comes flying in. It curves up and travels towards where the star of the Dark Planet once rested. "Be reborn, dead star." The blast explodes, giving life to a dead star as the dark planets' red wastelands are illuminated. In the distance, Fu giggles with excitement.
"He's finally done it! What will this form look like? It's time to see!" Fu yells and laughs, bouncing in place with excitement. The pillar slowly clears, revealing a human hand and red cat tail. Broly stares on in shock at the huge amount of power as it is finally revealed in full. The Cat God Form. Red hair, eyes crimson, and burning with conviction. A red tail that waves around, the whiskers carrying a flaming orange glow. The face is revealed as mine, as I stand calm.
"This is the end for you, Broly. Keep Trunks safe, you two. Broly is my fight to finish." I tell all four around me with a calm tone, a serene aura flowing around me in mixes of red, orange, and yellow with blue flickers of light coming off of the aura that disappear moments later. A heart set ablaze, my power has finally exceeded its previous limits. "Set your heart ablaze. Burn bright. Don't die until you reach the goal."
Broly lets out a primal roar, finally going all out. The final battle is set to begin.
