>>114968420Suyin is Toph's other daughter and Lin's (the chief of police from season 1) sister.
In the past, Toph was the chief of police of republic city with Lin looking up to her. Suyin was a criminal who got involved with gangs and constantly doing all that shit. One day Lin intervened and was going to bring her in leading to Suyin scarring Lin's face. She is caught, but ultimately she gets off scot free. Toph retires as chief of police over the whole debacle, and Suyin gets sent away to live with her super rich grandparents. Lin is rightfully fucking furious.
From here Suyin eventually fucks off from her rich house and goes back to CRIME TIME with her newly formed crew outside of Republic City. Since apparently Suyin has SSS+ tier luck she gets literally everything she ever wanted while facing no consequences ever. She gets a perfect family, gets her own private city likely won with her loot from her crimes, and a good amount of influence. She supposedly apologizes to Lin but it is pretty half assed boiling down to how Toph got over it even though we all know Toph gives jack shit about anything.
Season 3 leads to them butting heads but again Suyin gets made out to be the righteous one and Lin has to apologize to HER, the person who led to Toph quitting, scarred her, and got away with essentially zero meaningful punishment.
She likes to talk big about changing and cleaning up her act but it is obvious she hasn't changed at all. The instant anything gets in her way she throws a colossal bitch fit. When the Earth Kingdom is falling apart due to the Earth Queen's assassination she refuses to help, but when her protege wishes to save the EK and step up herself she gets pissy that she defies her and disowns her. Overall this shit continues but she never gets called out and keeps getting everything she wants.
