Thanos

Thanos was a character who only appeared in Annoying Orange vs. Thanos. He was seen scaring away Pear after he saw him. Thanos then tried to correct his name to Orange and Sis, who kept mispronouncing it. Thanos told them he came for the yellow stone. Orange then gave him the stone, that he used for a tooth. Thanos was about to say, “I am Inevitable”, but Orange and Sis tossed his Infinity Gauntlet playing catch. Thanos then got annoyed and said he would do something and Sis asked him if it was “snap”, and Thanos responded “yes”, but Sis was actually warning him about the snap. Orange then snapped the Infinity Gauntlet and Thanos disintegrated to dust. 
=== Trivia ===
* After being disintegrated, Thanos said “I don’t feel so good”, which is a reference from Infinity War, when Spider-Man said it.
