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

Legendary Devil, Power Beyond

Broly fires a huge green ball of ki at me, forcing me to grab it and add my own ki and send it flying back at him. "How are you here, Broly? I don't care what happened to your Paragus. Who sent you here?!" I question Broly, wanting answers for this. Broly lets off a menacing grin, firing a counter blast with more power to nullify the one I sent his way. An explosion of emerald, black, and white covers the Dark Planet, blinding myself, Goku, and Broly. I listen to the movements in the air, not relying on my sight to find Broly.
"Well, since you're going to die, I'll tell you." Broly finally responds as the light slowly clears up. Goku, who's been barely keeping up, comes out from behind a rock he was sent behind by the explosion as Broly continues. "Some woman with blue skin promised me a good fight with a strong opponent if I went with her wherever she was taking me. Another timeline, or something like that." I move in with instant transmission and cloning, fighting against Broly with 4 clones. "She was right, as well. You're making me fight seriously, but I'm far from finished!" Broly laughs, defending against me and my clones as he lets out more power, causing me and the clones to jump back as Goku instant transmissions in front of Broly, trying to attack him. The attacks do nothing as Broly's hair grows out, and he retains his eyebrows. My eyes widen in shock and horror at the form, as I recognise it. Immediately transforming right into Primal Cat alongside my clones, I make myself huge, pulling an arm back as I then throw a punch. Green light blinds me and Goku, and I feel my giant fist caught.
"No...Goku, teleport away! You can't handle Bro-!" I shout in panic but get cut off by a huge blast from below. I quickly jump back as one of my clones teleports away, the others appearing above the blast to fire a counter blast. White and green light cover my vision, but I get suddenly sent flying across the planet, my giant form fading as I look to where I feel the pain. My hands are burnt. My arms were slightly burnt by the blast, too. I hear a cackling far away, coming closer, too. When my vision clears, I flip backwards as I see God Broly, nervous about my situation. I sense Goku is gone, too, most likely to get help. I feel something else. No, someone else appears on the battle site. A burning attack hits Broly from the back, leaving some burn marks in his back. I look behind Broly, seeing something worrying. "Am I in trouble here, Trunks?" I ask in a concerned tone, worried. Trunks shakes his head and transforms into Super Saiyan God. Then, two more people show up. Xeno Goku, and Xeno Vegeta, already in Super Saiyan 4 Limit Breaker. I muster the strength to stand with them, knowing things are going south fast. Appearing next to Goku with my clone via instant transmission, I merge the clone back into myself.
"Any more backup showing up?" Xeno Goku questions, curious and eager to deal with Broly now.
"Yeah, but it'll take a while for it to arrive. We need to fight for as long as we can." I respond, knowing who's coming due to the information transfer when the clone was merged back into me.
"Then let's fight for as long as possible to buy time!" Trunks shouts in addition, his Super Saiyan God power stable and stronger than ever. I feel something swelling within me, but it needs a push. For now, another combination will do. My eyes don't change in hue, but they gain the crystal appearance of the purified Ultra Supervillain power, my white aura flashing a radiant blue as red lightning dances around me. This is my answer to keeping up, but will it be enough? I don't know.
