Byleth 

The main character of Fire Emblem: Three Houses. He is a former mercenary who took a teaching job at the Garreg Mach Monestary. He has the Crest of Flames, a mysterious yet powerful Crest that allows him to wield the Sword of the Creator. Fans of the Super Smash Bros. games really dislike him.

Aided by Sothis and with the Sword of the Creator in his hand, Byleth rushes into battle.

Byleth Salt 

The feeling some hardcore Super Smash Bros fans have towards one of the DLC fighters in Super Smash Bros Ultimate, because Byleth is just another Fire Emblem anime sword fighter in their eyes. Which is understandable on some level, as there are 8 fighters the series has in the game, even though the series is not as popular as Pokemon or Super Mario.

Fan 1: F*ck Sakurai! Another Fire Emblem character?!
Fan 2: Chill out with the Byleth Salt man, at least He/She has a unique fighting style.
fan 1: Yeah, I guess you're right, I got carried away with the salt there....

Byleth Syndrome

When someone expresses average to extreme hatred for something purely for its existence

Guy 1: Hey did you hear about the new Metal Gear Game?

Guy 2: Yeah it's garbage

Guy 1: Why?

Guy 2: Because Kojima is no longer working on the series so it's obviously a cash grab

Guy 1: Did you play it by any chance?

Guy 2: No, why would I ever play that piece of shit?

Guy 1: So you don't know if the game itself is actually bad or not?

Guy 2: Well... no

Guy 1: Typical Byleth Syndrome
