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

Divine Duality Omen Awakened

Black goes crashing into the moon, then through several other planets from several blows. I move with a speed that he can't track now, a streak of silver and purple across space. Using Primal Rosé is already showing flaws too, especially with the mind. It works similar to Primal Cat, which is similar to Young Jiji's Super Saiyan 5. Knowing I can only do one more attack, however, my body moves on instinct, teleporting him to the other side of the universe. A massive energy dragon coats a line of planets as I close the gap with the flying through space Black.

"Cosmic Dragon Fist." I say with no emotion, the attack hitting with full force. The damage done won't kill, but it'll heavily weaken him. At the moment of a galaxy sized explosion, I teleport away back to earth and crash down in front of my future self, forced into base. "Get... me... out of here."

Present timeline, 1 hour later.

A time machine appears at Capsule Corp, landing in the backyard as Bulma rushes out. My future self, having listened to me, gets me out of the machine as Future Gato hops out as well, setting me down in a chair. Another time machine appears moments later. Goku, Vegeta, and Trunks get out, weakened.
"What happened there?" Beerus asks as he looks over, seeing our injured states. Whis floats over, healing us, but mine takes longer.
"I finally accessed the blending of conflicting powers." I respond, bringing a smile to Whis as Beerus' eyes widen in shock. "It ran out pretty quickly, though. It was hard to control consciously." My future self steps forward.
"The power wasn't balanced." He adds on, calm. "Think of it like two starship docked together, trying to reach the same place." Everyone looks over, including the present Chi-Chi, Goten, and Gohan as they show up, wondering what happened. "Both ships are diverting power to each other, but they need to keep it equal, or one runs out too fast." I nod, gesturing for him to continue. "By keeping the power equal, you extend how long you can use that power. It is conflicting by nature, but you can balance it." Whis nods at my future self.
"An interesting visualisation, but true." He compliments with a smile, calm as Beerus nods in acknowledgement of the idea. "If you can balance out the energies, you can use it for longer. If you'd like to train in my staff, you're welcome to." Whis looks at me, wanting to know if I want to.

There's a moment of silence.

"I want to bring my future self in too." I say in response, looking at him. "He's not achieved the God forms I have. He needs the buff to keep up. Also, relying on this timeline for help constantly won't be good." Whis looks at my future self, and he nods in response. With a smile, Whis gives us both new clothes and sucks us into his staff.

2 hours later outside of the staff.

"So that's what happened...?" Gohan asks, having been told about Trunks' and my future selves situation by Future Gato. He nods, looking at his present counterpart.
"You seem pretty tough. Potential unlock?" He questions with a calm expression, but the scar on his face and his hardened demeanour show another story. Gato nods.
"Yes, I got my potential unlocked." He says with a neutral look, seeing the struggle this future version went through. "Elder Kai unlocked my potential. If we win this and revive everyone that was killed by Black and Zamasu, along with before Babidi and Dabura, you should get him to unlock it." Future Gato nods, then sensing me and my future self enter the room and looking over.
"So, everyone is informed?" I ask with a calm and focused look, the results of training showing. My future self standing with a new set of clothes transforms into Cat God as a show of his growth. Gokus' eyes widen, but Vegeta smirks.
"There's more you're hiding, isn't there?" Vegeta questions with a smirk, sensing more than what's being shown as my future self nods, briefly flaring a blue aura as a form of hinting.
"We plan to refine it in the Time Chamber later." I say with a relaxed look, knowing there's more ahead in power. "I was able to refine the new power I got, but it's still unstable. Zoom is key to balancing out the power with me as I tend to use more power than necessary, breaking the balance." Whis nods, watching how I act. The power my body contains still isn't balanced, but its close. "What matters is I can use it consciously. I also did enough damage to weaken Black for an extended period. We should strike while the iron is hot." I look at the present Zamasu. "We lost our battle. You should pursue your plan." He nods, teleporting outside and setting down the Dragon Balls.
"What's his plan? He wouldn't be able to help with his strength, and neither can we." 18 says from another part of the room as she sits with Krillin and Maron, who actually looks her age here because I'm not a dumbass.
"You'll see." I respond as I open the window.
"Come forth, Eternal Dragon, and grant my wish." Zamasu calmly says, watching as the Dragon Balls glow, Shenron taking form. "I wish to help my new mortal friend in this time of struggle. Grant me immortality, so I may aid in his battle." Shenron takes a moment. His eyes glow.
"Your wish has been granted. State your second wish." He responds, waiting for a second wish. Zamasu thinks, wondering what he could wish for, then knowing. "Create a supply of 20 Senzu Beans in a bag, as they'll likely encounter struggle." Shenrons eyes glow once more. "I have no more wishes to make, you may return to dormancy.
"Very well. Farewell." Shenron responds, vanishing into the Dragon Balls. They then rise up and scatter. The Senzu Beans in a bag appear in my hand, bringing a smile to my face. Though my thoughts dwell on something else. What's going on with Black?
