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

Star of Deathleham, Christmas Evolution

Appearing within the Star of Deathleham, I stare down Hatchiyack with a glare, Zangya concerned, Granola angry that the peace he has is being ruined by this fake Santa. Using Oatmeal and his vision, Granola identifies vital points in Hatchiyack as the Tuffle begins to monologue.
"Ah, the Galactic Patrol. Welcome to my workshop. The Star of Deathleham!" Hatchiyack declares, grimacing. Zangya cuts off the monologue.
"Workshop? Like Santa's Workshop?" She questions. I become angry visibly, letting out a groan.
"FUCKING EVIL SANTA! SERIOUSLY?!" I shout in frustration, annoyed. "Have we not done enough good to have this not happen?!"
"I'm the one with the list, I'm the one who decided naughty and nice." Hatchiyack begins, his tone angry. He points at Zangya first. "Zangya, the Space Pirate who killed masses of innocent people! The one who abandoned her own allies to be safe with the enemy! So much death, and all for what?! To leave it behind in hopes your past sins would never haunt you?!" Zangya slowly becomes more annoyed, a bit guilty for abandoning Bido, Bujin, and Kogu too. She knows her path is right, though, so she accepts the guilt and blame. Hatchiyack points to Granola next. "Granola, the Bounty Hunter! The child who killed for money! The one who killed innocent people and those trying to walk away from a criminal life! You stained your hands with innocent blood on the command of the Heeters, and you betray them! Ally yourself with a friend of a Saiyan! The very species that killed your people!" Granola becomes enraged, but Hatchiyack points at me next. "Finally, you. The man from another world. William, the one who broke fates original course! The one who broke the timeline, after so much divine work! The only gifts I have for all of you are-" Hatchiyack is cut off by a sudden huge beam from Granola.
"Shut up and die, you bastard!" Granola roars, firing off a large killing beam. Hatchiyack screams and disappears in an explosion.
"I win, Merry Christmas for Granola!"
"Granola, no!" I groan in frustration.
"Granola, yes!" Granola counters with a smirk. There's a moment of quiet before Zangya breaks the silence.
"Did we just...save Christmas?" Zangya asks, curious and wondering if this is over.
"No, it isn't over. Give it a moment." I respond, waiting. The machine in front starts to glow as Hatchiyacks' voice echoes.
"Fool, you cannot kill the mighty clause!" Hatchiyack roars, finally evolving into his truest form.
"I knew it..." I mutter under my breath, annoyed by all this, but focused. The machine warbles as Hatchiyack is revealed in his new form, looking how I recognise from Plan to Eradicate The Saiyans.
"You cannot destroy me. For you see, what you destroyed was merely a shell left being from my...'Christmas Evolution.'" Hatchiyack reveals, smirking with malice.
"Oh Kami damn it, he's gone Super Santa!" I shout in panic as this version is far stronger than he should be.
"That's right, and I'm a grumpy old elf. Last Cerelean, yule pay for your crimes against the mighty clause." Hatchiyack finishes, now no longer holding back.
"Ah, like the log-oh Holy Night!" Granola quickly yells in panic, then getting sent skidding backwards to the floor with a single blow.
