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

Multidimensional Chaos

In a world where quirks are what defines power, a huge crack in reality opens in the sky. Streaks of blue and pink crash into the ground, the walls of reality unstable as Black and I slowly stand, forced from Primal Blue and Rosé to regular Blue and Rosé. "Only one of us will be standing by the end of this, you arrogant prick." I say with a glare, my blue aura flaring as it begins to grow. A crimson glow is added on top. "Kaioken." Black caught off guard, doesn't expect it when I rush in and punch him, breaking reality again. We fall again, forcibly reverted to base form. Landing in a galaxy torn by war, Black and I enter a wrestling match through blaster fire, then physically brawling across the surface of the planet. Shockwaves devastate the area, and all the fighting stops for a moment as we punch each other in the face. For the briefest moment, we transform again and break reality. Forced back into base form again, we stumble against temple walls. Black falls down the stairs, and I fall against a wall, but I stand first. Forming a ki blade with what energy I have left, I glare down Black.
"I'm going to put you down here, mortal. Then I'll find my way back to those other mortals and kill them!" He declares, drawing attention from robe wearing people, looking ready to intervene.
"As if I'd let you hurt them. I'll kill you myself." I retort with a murderous tone, running in the him. "Get the hell over here, I'm ending your Zero Mortal Plan!" Black forms a ki blade in retaliation, starting a clash beginning between us again. Pushing harder, I kick him away and launch him backwards, then slashing down at him. Black rolls away. "Annoyance, get back here! I'm going to get you one way or another!" Marching him down, I slash at him and force him to block. The clash of ki blades cracks the ground as we push against each other. "I won't let you go unpunished!" Hearing several blades igniting, I realise where I am. The Jedi Temple. Kicking Black away, I glare him down as the Jedi Council moves to intervene. Mace Windu ignites his purple blade, sensing the malevolent power within Black.
"Damn mortals, one after another! Insolent worms!" He shouts as his ki surges. Everyone gets blasted back, but I launch back and try to punch him, only for a ki blade to go through my stomach. Coughing up blood, my mind goes dark for a moment.

The sound of sabers igniting and use of the force silences is drowned out. My mind visualises something in the darkness.

Two spaceships.

One, Ultra Instinct.

The other, Energy of Destruction.

Both docked and sharing power to reach the same place.

Complete balance.

As my body lays on the ground seemingly lifeless, the Jedi fail to hit Black as he toys with them, now confident. A heat and pressure blended with a calm begins to wash over the area. Black slowly turns around to the sight of me... standing. His eyes widen at the aura. It's more intense, yet only my eyes turn silver. Divine Duality Omen awakens once more. Black and I vanish in a streak of energy, leaving a huge crack in reality as we break dimensional barriers. Some Jedi were injured by Black, but they'll live.

Breaking into the site of a demon school, I flip past two demon girls flying slow as Black slams into a rock spike.
"Wake up, I'm not finished fighting you, Black." I say, calm and collected as I ignore the shock of the demon girls. Someone that clearly isn't a demon in this world. Kachin blocks smash into Black, but he forces himself into Primal Rosé and fires huge blast in retaliation. The girls panic, but I stop it with a single hand. I turn my head and look at them. "Leave. I'm going to deal with this one." The girls look at my calm expression, somewhat red in the face, but listen and continue flying at a faster pace. In seconds, my fist collides with Blacks beam, destroying it. He flies with speed at me, but it doesn't take long for me to counter him with the most disrespectful backhand in the entire multiverse, breaking reality and returning the fight to the future timeline.

Black teleports away to Zamasu, trying to initiate fusion with him, only to be met with a vengeful glare.
