Lancer
Lancer is a character in Deltarune who is the "bad guy" in the beginning, but later on, loses a battle to join your team. He has also become a meme because of his silliness, and various faces.
Example:
Man: "Yo did you play Deltarune yet?"
Man 2:"Of course dude! Lancer is my favorite character!"
