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

Future History, Final Part

5 years have gone by. Capsule Corp is now occupied by Bulma, working on the time machine. I, however, am not there, as I push back Android 17, firing a huge barrage of ki blasts at Android 18 to blind her so I can finish off one of them at least. Seeing an opening, I take it. Flying in, I combine my Warrior Cat form with Kaioken, something I've been developing during the last 5 years. I punch off the head of Android 17 in one clean move, destroying the body in both parts, then flying towards Android 18 and incinerating her. Knowing this isn't over, and Cell is a problem still, I power down to base to not be sensed by him right away as I teleport to where I sense an amalgamation of ki, it's so unnatural I can't not notice it. I appear in front of the still developing Cell. "Not this time, you bug freak." I simply say, my tone cold. I've become cold to opponents over the last years since Gohan died. I see Trunks as a second son, and I won't let him get hurt by this. Powering up right to my maximum, I wipe away Cell in a single blast. Nothing is left. Then, destroying the sublab, I teleport back to Capsule Corp, where Bulma has finished the time machine. She smiles at me as I arrive.
"The time machine is ready to go. A round trip there and back is all it can do, though." She tells me, but I remain calm.
"I know." I reply, cold and calm in return. "I have the plan memorised. Get Goku the medicine, force the Heart Virus out of dormancy early with a punch to his heart, give him the medicine, warn my past self so he can warn the others, leave. Got it." Bulma nods in acknowledgement of the plan, then stepping out of the way. I walk to the machine, noticing the word 'Hope' written on the machine. "Could use some cat ears." I take her marker from the table and add a cat ear to the H, and another to the E. She giggles a bit at it, a moment of peace. My place in this story for now, however, is over, as I hop into the machine and make the trip into the past. Now, you'll experience this from the version of me you're familiar with.
