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

Legendary Devil vs Primal Cat, meeting

I stop my ship outside of South Galaxy, making eye contact with Broly, who grins with malice at me within his barrier. I get on my space suit, sending the ship down to the nearest planet as I exit, flying over to Broly.
"If we fight, we do this on a planet with a breathable atmosphere." I demand, stern and sharp in my tone.
"Very well, you may choose where you get to die." Broly responds, his malicious grin wide. Before I can even react, I'm suddenly grabbed and thrown down to the nearest planet where my ship went, crashing down in a crater as my space suit is destroyed to soften the impact. Slowly recovering, I find the strength to stand up pretty quickly, unable to see Broly due to the darkness. I realise where we are. The Dark Planet, home of Demon Beast Yakon. Relying on ki sensing and hearing, I quickly move away from a sudden attack, transforming into Warrior Cat without hesitation. What I don't expect, however, is how high my ki is and that someone could teleport to it. A certain Saiyan I know should have instant transmission at this point in the timeline, who possibly went to Yardrat to learn it before the Androids, appears. Broly becomes enraged.
"Kakarot...Kakarot...Kakarot!" Broly roars out in rage, growing in power as he explodes his legendary power.
"Woah, who is this guy?!" Goku questions, shocked at the power.
"A version of Broly that shouldn't be in this timeline." I respond, then flying in immediately to square up with Broly. The battle I've been training for is set to begin on the dark planet, the home of Yakon.
