Mario, Sonic, Mega Man DEATH BATTLE! (Season 6)

Goku Black VS Sirin

Two misanthropic godly beings in possession of the bodies of kindhearted and heroic protagonists are about to fight for their lives.

Interlude

(*Cues: Wiz & Boomstick - Brandon Yates*)

Dr. Eggman: Goku Black, the body-stealing arbiter of divine justice.

Bowser: Sirin, the body-possessing Herrscher of the Void.

Dr. Eggman: They're arrogant, narcissistic, egotistical, and misanthropic with a big grudge against mortals and all of humanity.

Bowser: And said grudge has cost them to have a goal to annihilate everyone in their path. He's Eggman and I'm Bowser.

Dr. Eggman: And it's our job to analyze their weapons armor and skills to find out who would win a Death Battle.

Goku Black

Dr. Eggman: What consumes the thoughts of a god? What do immortals dream of with all the time in the world? In Zamasu's case, his one goal was divine justice.

Background
Real name: Zamasu
Age: Most likely hundreds to thousands
Height: 5'9" | 175 cm
Weight: 136 lbs | 62 kg
Species: Core Person (formerly), Saiyan
North Kai of Universe 10
Ex-apprentice to Supreme Kai Gowasu
An abnormally talented fighting prodigy
Likes drinking tea

Bowser: Yeah, this guy's got major Final Fantasy big bad energy all over him.

Dr. Eggman: As the assistant to Universe 10's Supreme Kai, Zamasu prized, above all else, cosmic order and natural beauty.

Bowser: Well I mean you can't go wrong with wanting beauty in the world am I right?

Dr. Eggman: Unsurprisingly, Zamasu despised the inherently chaotic nature of mortals, being seemingly unwilling to lift themselves out of their own cycle of violence and stupidity, like some people we know.

Bowser: Yeah I think I know what you're talking about. His heart was clouded, until the day he met Son Goku.

Dr. Eggman: With god ki, Goku could match blows with the God of Destruction, Beerus. Their clash nearly destroyed the entirety of Universe 7, a cosmological structure at least nine times larger than our own universe. At most, it could even be as large as 13 times greater than ours. Actually it has likely to be even bigger than that. Uh, side note, it's worth mentioning that when two Gods of Destruction fought, they were capable of casually destroying 2 of these universes.

Bowser: And since the shockwaves from their punches travelled across Universe 7 in seconds, they'd have to be hitting way faster than light.

Dr. Eggman: Goku was tapping into his Super Saiyan God form for this, though clearly not at its full strength. While the exact multiplier for Super Saiyan Blue is unknown, Toriyama himself has directly compared it to the original Super Saiyan form.

Bowser: And don't forget, Goku trained with Whis and fought in the tournament with Universe 6 before Zamasu caught up with him, so by that time, he was way stronger.

Dr. Eggman: Here was a mortal with the powers of gods beyond even Zamasu's abilities. Someone who could bring his dreams to fruition.

Bowser: So, Zammy did what any villain like us would do in that situation: kill his master to become the Supreme Kai, wish on the Super Dragon Balls to switch bodies with Goku, and kill every single mortal in the universe.
