Vegeta: Hmph so the two of you fused?
Goku: Vegeta-
Vegeta: Hell No I will not fuse with you never again!
Rex: You guys can fuse?
Vegeta: Yes we can but I don't need to fuse to defeat you! Kakarot I am fighting first you stay in the back and look like an idiot!
Goku: Ok then Vegeta.
Goku jumped on a rock and watched while Vegeta battled Pneuma and Rex needless to say Vegeta was getting pushed back.
Goku: Man they are pushing Vegeta back I can't help but be excited!
Vegeta: Grrgh...
Rex landed a square swipe to Vegeta's chest.
Vegeta: Ok play time is over brat!!!
Vegeta turned into Royal Super Saiyan Blue.
Vegeta: This a form beyond Super Saiyan God meet Super Saiyan Blue!!
Vegeta jumped at them before they could even speak but Vegeta was still getting pushed back.
Vegeta: You all are pretty powerful but I'm going to end this in one blast!!
Vegeta jumped back and threw his arms arms up and out as 2 balls of energy formed in his hands as he put his arms infront of him.
Vegeta: FINAL FLASH!!!!!!
Vegeta shot a massive yellow blast at them as they took it head on as they looked like they were on the ground.
Vegeta: Hehehe...HAHAHA!!! That's right I am the Pri-
Rex: Don't underestimate us!
Vegeta was shot away by a blast Rex shot sending him off into a mountain and Vegeta passed out.
Goku: Woah you beat Vegeta like that? Ok guess it's my turn!
Goku jumped down to them as he turned Super Saiyan Blue mixed with Kaioken.
Goku: This is Super Saiyan Blue Kaioken!!
Rex: Alright let's do it Goku!!
Pneuma: No holding back!
Goku leaped at Rex and Pneuma clashing with them as they both were on a even playing ground.
Rex: Goku question what are you to everyone in your world?
Goku: I am considered a monster to some a brainless ape to a few but to most I am a sign of hope someone they can relate to I'm a husband and also a father I am protector of the innocent I am the light in the darkness I am truth. Ally to good!! Nightmare to Evil!!
Goku said his hits powering up.
Goku: Infact I relate a lot to you Rex and Pyra, Mythra and Pneuma.
Rex: How so Goku?
Goku: Much like you Rex I believe there is good in very single person even if they have killed innocent lives even if they hurt the closest people to you.. I should know my best friend died to one of those heartless monsters. And like you Rex I never knew who my parents were and I was an orphan too.
Rex was surprised that Goku someone he just met knew and related to him this much.
Goku: and like you Pneuma, Pyra and Mythra I regret some things I did in my past I hurt loved ones with my choices that ultimately saved them. I want to give you two some advice keep fighting the good fight and keep your bonds strong you two love birds!
He knocked them back and started charging a Kamehameha while Rex and Pneuma shot a powerful energy blast at him knocking him down as he went to his base form.
Goku: Grggh...
Goku slowly got up because he knew if he stayed down he lost..
Goku: You all are good but I wont lose...
Rex: Sorry to say Goku but you lose.
Rex swiped a powerful sword swipe at him and Goku went through it he disappeared and then reappeared behind Pneuma and Rex
Pneuma: How in the world did he do that?
Goku turned around and opened his eyes and they were a piercing silver Rex leaped at him and kept swinging his sword at Goku he kept dodging everything and landed a square punch to Rex's stomach knocking him back.
Rex: Goku what is this??
Goku: This is Ultra Instinct!!
