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

Multiversal Exploration Arc, Berserk Destroyer

My training with the Fireballs goes on as I learn a hybrid of Rozie's ki blast redirection and the Hellzone Grenade, creating a new attack. The Cyclone Grenade. Using it on all three Fireballs at once during a 3v1 where they force me into Warrior Cat, a rain of ki blasts swirls around in a chaotic storm around them, causing Rozie to try add her own ki blasts in to counter as Ribrianne powers up a blast of pure love to defend herself. Kakunsa jumps up, trying to break my focus by firing ki slashes at me from her claws. Snapping into Primal Cat combined with the Purified Ultra Supervillain power, I dispel the attacks with the pressure and release the Cyclone Grenade, causing a chain of colliding explosions that even launch me backwards. The dust in the area is hard for me to see through, but I let my instincts take over as my body dodges a triple ki slash, creating a ki blade and cutting through another 6 slashes as the ki blade shifts into a destructive purple as the dust clears, thousands of ki blasts swirling around me.
"Impressive, Rozie. You're using my own attack against me. However, you didn't consider how much ki control I need to have to use this attack without losing much energy." I taunt through the glow of the blasts, calm as I notice some ki slashes in the wave, even some heart-shaped pink ki blasts. "Your teamwork is impressive. Adapting to me as I grow stronger."
"We've been a team for so long, so what else would you expect?" Ribrianne above questions me with a smile on her face, Rozie suddenly coming in from below with an uppercut, causing my ki blade to vanish as I dodge, but Kakunsa is there next, and I barely stop her attack, but it cuts my chest.
"We're strong separately, yes..." Rozie adds on, flipping outside of the ki blasts as Kakunsa flips above with her own blast charged for the chain to start early.
"...But we're unstoppable together!" Kakunsa finishes off as the ki blasts swirl in towards me, but I remain calm. My body starts dodging on its own, weaving around blasts, but one grazes me. The graze starts off a chain of me being hit by explosion after explosion, breaking my focus on using the properties of Ultra Instinct, causing me to immediately defend myself with a slowly breaking ki barrier.
"You're all amazing. Working together so seamlessly like this! It makes me excited! I feel alive!" I shout through the explosions to them, but I can't see them through them as the ki barrier breaks. A roar comes from within, but it goes silent as all the blasts hit. Smoke and dust blow through the area as Kakunsa looks through the smoke, hoping that did something. Pressure from the smoke suddenly blows away the Fireballs, a blue flare blowing it away as I stand heavily injured in my blue form, but something is off. I stand silent, eerily quiet.
"Looks like you're in stunned silence because of the power of our combined love." Ribrianne taunts, smiling at the fact they were able to do this much damage to me, but Rozie's expression is one of looming dread as she watches my aura. It isn't blue entirely but shifting into a worryingly ominous purple. In the mindscape, however, Zoom and I stand staring at my observations of how Heles uses her energy of destruction. Single target destruction. What I want is multiple target destruction. What Zoom wants is multiple target destruction. Purple ki flows around Zoom and myself, our combined destructive desire and training with Beerus awakening something.

Site of a destroyed planet...

Heles floats as she begins to sense the shift in my ki. Destructive. Primal. The very same feeling as a God of Destructions Ki. Her expression turns to horror at the feeling of my energy. It's so much higher than hers. How? He's a fusion, sure, but this is more than a fusion boost. This feels like a combined destructive instinct combined with God Ki.

Training ground...

The fur on my body disappears as the purple glow slowly covers more of my body, my hair reverting to normal. Rozie steps back, recognising this as she grabs Ribrianne and Kakunsa, flying away as fast as possible with them.
"What's going on with him?!" Ribrianne asks in panic. Rozie doesn't dare look back as she knows what's about to happen.
"He told us he was training with Beerus for a few months. He also told us he learnt how to partially channel energy of destruction." Rozie starts off as the perspective shifts back to me, the aura whipping around in the air violently. I'm still silent and unmoving. "He was also observing through a crystal ball how our God of Destruction used her power, and we pushed him to his limit." The perspective shifts to Heles as she teleports in with the help of her Supreme Kai, who teleports out immediately after. Heles starts releasing her full power, drawing my attention. My head slowly raises, revealing there's no physical changes, but my eyes, however...they carry a primal and destructive instinct. Purple auras collide in energy of destruction rapidly whipping against energy of destruction. Battle lines are drawn, a berserker against beauty. Heles has also understood something about me now as she talks first.
"Your body has adjusted to this world but remains anchored to your old world. Such destructive instinct is impressive. You clearly have more potential than any other God of Destruction I know, but I won't lose to you." Heles states with a stern expression as I tilt my head at her. My mind is entirely in the backseat and asleep right now, so there's no other way to break this state than combat. She points up to space. I nod and fly up without restraint or ki control, stopping instantly once in space, turning my attention back to her as she looks at me. Silence fills space for a moment, but my body slightly twitches, that berserk instinct slightly fading, but coming right back.

Unknown Location.

I walk through an endless sea of purple flames with Zoom, unharmed by the flames as we search for a way to regain control of our fused body. Zoom and I both sense chaos in the physical plane, so I speed up as he climbs up onto my shoulder, then jumping off it to get some speed. I don't like not being in control of my own body, epically in a situation like this.
