Yandere traitsEdit

He uses his adorable charm to fool people into thinking he's just some innocent kid. When he starts a "relationship" with Mabel, he makes sure to make it a public display, making it difficult for her to turn him down. On multiple occasions, he's attempted to kill Dipper, Mabel's twin brother, because he believes that he has tried to come between Gideon's relationship with Mabel. Even when she tells him directly that she will never be his girlfriend, he continues to obsess over her and is determined to make her his queen.
