Mustachible is an evil, mustachioed counterpart of Mark Grayson pulled from a parallel timeline where he embraced his Viltrumite blood. Recruited by Angstrom Levy for the Invincible War, this variant rampaged across the mainstream Earth until Tech Jacket cut him down in orbit.
What separates this variant from the ordinary Invincible is the slim, sharply angled mustache favored among Viltrumite men. Below that, his frame mirrors Mark's exactly. Rather than a standard trooper's kit, he wears an elevated take on imperial dress reserved for the empire's upper ranks, its cut echoing his own hero costume with the I-shaped emblem across the chest and a darker set of tones.
Because he never utters a single line on screen, almost nothing about his inner life is confirmed. His frozen, severe expressions point to a fighter who is cold and merciless, thoroughly given over to conquest. He has thrown his weight behind his father's campaign to seize Earth and leans fully into Viltrumite custom, from the trademark facial hair down to the tailored officer's uniform worn by the empire's higher-ranking soldiers.

Naruto vs Luffy with the twist nobody asked for: Luffy tickled Hinata on date night, and she kind of liked it. We break down the whole fight and commit to a winner....

There are no women on Namek. That isn't an oversight, it's the biology. Why we handed Piccolo the one thing his own species rules out, and why it had to be trap soul....
Little survives about this variant's origins beyond the fact that he turned villain in his own reality and eagerly backed his father's bid to hand their Earth over to the empire, readying it for the arrival of the Viltrum forces. Angstrom Levy gathered him among a crowd of malevolent Invincibles to unleash havoc on the primary universe, igniting the catastrophe remembered as the Invincible War.
Pouring through Angstrom's rift alongside the rest, he set about wrecking everything below. High above the planet he crossed paths with Tech Jacket, and the two clashed in the void. He streaked toward her at blistering speed, weaving past her barrage of energy fire, but a point-blank blast from her helmet knocked him back just short of contact. Their duel dragged on for two days off screen before she finally overcame the hybrid's brutal durability and killed him, leaving his ruined body adrift among the stars.
His rampage flattened cities and entire nations and kept Tech Jacket from reinforcing weaker heroes for much of the conflict. He was the last variant to fall during the war. Afterward the GDA recovered his corpse and earmarked it, along with the other slain doubles, for D.A. Sinclair to rebuild into a ReAniman. As a Viltrumite and human hybrid whose alien genes overwhelm the human half, he carried the near-complete package of the species: flight, immense strength, resistance to harm, dazzling speed, rapid healing, and the stamina to trade blows for days without air in open space.
Mustachible was killed by Tech Jacket after a brutal duel that lasted two days in orbit above Earth. Their fight took place during the Invincible War, and she finally overcame his Viltrumite durability, leaving his body adrift among the stars.
The slim, sharply angled mustache favored among Viltrumite men is the one physical trait that sets Mustachible apart from the ordinary Mark Grayson. Mustachible is an alternate, evil version of Invincible who embraced this look along with his father's imperial ambitions.
Mustachible's real name is Markus Sebastian Grayson, the same identity shared by the alternate-timeline Invincible variants brought in by Angstrom Levy.
Mustachible fought Tech Jacket after Angstrom Levy pulled him into the primary universe as part of the Invincible War. He crossed paths with her high above the planet, and after a two-day battle in the void she used her helmet's energy blasts to finally kill him.
After the Invincible War, the GDA recovered Mustachible's body along with the other slain variants. His corpse was earmarked for D.A. Sinclair to rebuild him into a ReAniman.
