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

Multiversal Exploration Arc, Mirror Match

Zoom and I stop in front of two figures that look worryingly similar to us. It looks like our fused look, but without pupils. Entirely running on instinct.
"You run on instinct. That's what you are. These destructive instincts manifest." I state in a calm tone, calming my breathing. The Mirage looks at me.
"Destroy. Destroy. I will destroy you!" The mirage blindly says, rushing in without any thought. Quickly defending myself, I jump away with Zoom.
"We can't attack it. That aura of destruction is dangerous. One touch, we're done." I warn, now focusing in and properly locking in. Zoom runs off elsewhere for some reason, but I don't question it as I struggle to evade attacks, rapidly trying to figure out what's going on. Falling into base instincts immediately, my body starts moving on its own briefly, flipping over the mirage and kicking it in an opening behind it. The mirage has a large hole in it.
"You won't destroy me. Not before I destroy you!" The mirage shouts in anger, firing a Hakai. I barely avoid mid-air while trying to stop my fall or catch myself in some way.
"I see what's going on here. You're more a primal force, like Kid Buu. You're a destructive force I need to overcome with something. So what if I counter with those same instincts?" I say out loud, causing the mirage to stop for a moment. The only answer I needed was that. I let myself become fueled by rage and instinct, but I keep my mind awake. Ultra Instinct and the power of a God of Destruction in one is what this power is. Unconscious movement. I need to keep my mind and body separated, but my mind must remain awake. The mirage charges forward, but my body moves again, throwing a blow at the arm and causing it to disappear. My own willpower causes a change. The mirage starts to become less physical. More see-through. Suddenly, the mirage doubles over in pain, its tail cut off and vanishing slowly as the back has been erased. The hissing form of Zoom comes running in, biting at the left leg and clawing it with rage as it falls to the ground, losing the leg. Everything shifts, and I'm in the physical world again, but standing over an exhausted Heles in a barrier in space. I move back immediately.
"What's wrong, beast? Not finishing me off? No, you aren't the beast. You weren't in control, were you?" Heles questions, figuring things out pretty quickly.
"I'm sorry, I lost control. Is anyone hurt?" I respond in answer, concerned for the safety of others around me. Heles shakes her head.
"No, people weren't killed, but you did push me this far and were hard to hit. What was going on to make you lose control?" Heles responds to me, trying to figure out what's going on here.

1 month later.

I've been training with Heles for a month now. Only 3 weeks before I have to leave universe 2, but I'm already planning my next stop. There isn't much to talk about in what happened up to now learnt new things, figuring out some more of my understanding of energy of destruction. A visitor shows up today, however, someone I'm not happy to see. Whis brings Frieza to the planet, who's currently bound by ki rings.
"Oh, it's you, you damn catman." Frieza starts off, a scowl on his face.
"Frieza. I see you've been revived. Let me guess, golden form since you want to insult the Super Saiyan that killed you?" I respond in taunt, calm but cold. Frieza grimaces.
"Why would it matter to you, furry? You won't kill me. Once I'm done with you, I'll-" Frieza attempts to aggravate, but is cut off as I punch him in the face right as Whis removes the ki rings. Frieza is sent crashing into the other side of the planet.
"Feel free to kill him, Will." Whis says in a calm tone, curious about my progress.
"With pleasure." I respond, immediately powering up into my blue form. Frieza, despite his injuries, transforms into his Golden Form. The next 30 seconds give me absolute satisfaction as I pummel him half to death in seconds, finishing him off with a Hakai. "I believe I'm ready to carry on my tour of the multiverse, Heles. Please tell the Fireballs that I was excited to keep going and had become close to them, so I didn't want to say goodbye."
"Of course, where do you plan to go next?" Heles responds, curious. I take a moment.

"Universe 10. That visit won't be long, because it's the gods I need to visit there. One in particular, I need to correct before he goes down a dark path." I finally respond, Whis freshening me up with a tap of his staff, then leaving in a beam of light.
