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

Time Travellers' Leave

"So, why'd you come BEFORE we went to Namek?" I ask my future self, calm but concerned. He looks at me.
"Fu made Frieza three times stronger." He replies, a tone of concern in his voice. "You need to get Goku to access Super Saiyan before the ship is ready. The key to the form I have is primal rage mixed with love." I nod at the explanation. He then stands up, taking out a capsule and throwing it down. It reveals a time machine, 'Hope' written on the side. "I'll be back in 2 years to help train everyone. You should learn everything you can on Yardrat. You'll need it. Frieza isn't the end of threats. We both know that."
I take a moment.
"Why two? Why not come back in 4, to match Trunks?" I ask him, confused. "With your warning, we can handle Namek. Fu has probably already powered up Frieza, so we'll be fine. Better yet, you can help me access your form. It looks cool." He lets off a chuckle, shaking his head.
"If I did that, Fu would make Frieza even stronger. That, or add Cooler to the equation. What you also need is to be fully synchronised with Zoom within you, along with an anger trigger to unlock this. Once you do that, you'll need to get Goku Super Saiyan, or he'll have to unlock it on Namek. If he's the same three times stronger as my timeline, Frieza will have a 60% of 180 Million. His full power will be a 360 Million, but this form has a 300 times multiplier, so make sure you get strong. You'll need it if Cell or Majin Buu gets powered up the same way. Fu is messing with everything." My future self warns, calm but just as stern as before when telling his story. It makes sense to me.
"You get all that, Piccolo?" I ask, turning to Piccolo, who was there the entire time. He nods.
"Of course. I'll warn everyone about the Androids and Cell, but keep the information of Majin Buu out, as he's from what I've read of his mind, 7 years out from Cell." Piccolo responds, calm and collected. I watch him fly away, then nod at my future self, who hops into the Time Machine, then taking his own leave.
