Too perfect and unrealistically competent in everything she tries, to the point where she unintentionally bends or breaks the story’s plot and character personalities to her benefit. She is extremely skilled and powerful in literally every conceivable thing, and everybody in the story ends up either in love with her or swiftly removed/killed, no matter their previous personality or needs. Her only flaw, if it even exists, is that she “cares too much about everyone”. Ignores her own hypocrisy.

Mary Sue syndrome personified

Linkman The Junkman Travels around the world, looking for various trinkets and items he can sell. Sometimes, he finds rare magical armors and weapons on his travels, and usually tries to sell them to anyone interested for a relatively low price. He also often sells objectively useless or mundane junk like colored rocks or worn boots. He looks like a ragged hobo. He has a strange massive staff on his back that has an unknown purpose that he keeps secret and always refuses to talk about if asked.
