Squilliam Fancyson

Squilliam Fancyson is an octopus who was originally from Bikini Bottom, but joined Thanos during the same time as "The Avengers" (2012) took place. He is a major antagonist in the film, serving as one of Thanos's servants. It has been stated that he originally knew Squidward from band class.

Appearance
He looks very similar to Squidward, but he has a big and important unibrow. He also usually wears a dark purple outfit.

Story
Squilliam, being one of Thanos's direct servants from Infinity War, has a relatively large part in Endgame. He first appears on Thanos's Sanctuary Ship where he talks to Alphys (imprisoned) in the lab during Act II. He then appears in the Memory Chamber along with Evil Bowser, Thanos, and Himiko Toga to extract Aqua's memories. He appears next in Act III to fight in the Final Battle, where he turns to dust while fainting much like he does at the end of the Spongebob Episode "Band Geeks".
