Thanos

"You should have gone for the head!"

- Thanos

Thanos is the main antagonist of the Marvel Cinematic Universe, serving as the main antagonist of both Avengers: Infinity War and Avengers: Endgame. He is a Titan who wants to eradicate half of all life in the universe so as to prevent overpopulation using the Infinity Gauntlet. He has made a few appearances in SMG4's bloopers, mainly in the ninth season.

History
Thanos was first referenced in SMG4: The Super Dudes, the entire blooper being an homage to Infinity War. In the blooper, Wario obtains the Power Glove, prompting Mario, Bowser, Fishy Boopkins and Steve to go and stop him. Near the end of the blooper, Wario shoots an energy beam at everyone, causing them to disintegrate in to dust, much like the ending of Infinity War where Thanos snaps his fingers with the Infinity Gauntlet, therefore destroying half of the universe's populace. Fortunately, Luigi crashes in with his Trash Bag identity and saves them.

Thanos finally got his first appearance in SMG4: 3 MILLION SUB FAN COLLABORATION!, appearing as a transformation of Fishy Boopkins to save his friends from some Master Hands. This version of Thanos is green-skinned and has blue super-Saiyan hair.

Thanos later appears in SMG4: Mario Waits in Line For Some Spaghetti, where he is seen waiting in line at the bank.
