I can’t believe it’s canon that Mai:
Walked away from Zuko after dismissing his fear of seeing his abusive father and it was never addressed as their introductory relationship scene
Told Zuko he was betraying his country when he went to defeat his abusive war lord father and never understood why he did what he did to end the war
Actively hates politics and does not care about doing the “right” thing for the world
Left Zuko with no protection while he was having multiple assassination attempts and was actively suicidal
Never asked about Zuko’s mother, tried to meet her, or help Zuko find her when that was the most important thing in the world to him
Told Ty Lee that Zuko was turning into his evil father because he had Azula help him find their mom, even though this is Zuko’s deepest fear in the world and she’s supposed to love and believe in him as supposedly his future wife
Rebounded after dumping Zuko with a guy who is in The New Ozai Society
Exploited this guy’s emotions who genuinely cared for her, despite them being a good match who both hated politics
Said that Zuko didn’t care about other people’s feelings one panel after he was up at night worrying to Suki (who actually listened and cared about him and offered good advice) about Tom-Tom’s emotional state just because he temporarily suspended the post of a man who directly went against the Fire Lord’s orders
Implicitly amped up Zuko’s death (in the same story where she’s hiding the fact her dad is trying to kill him and his family) when she asked “reserve a spot [in the fire lord’s burial chamber] for yourself yet?”
Saw her father try to murder Zuko, his toddler sister, uncle, mother, and step-father and hide it from Zuko when he asked directly if she knew anything
Excused her own behavior because “he’s her dad” and never had to apologize once
Twisted the blame onto Zuko because he has a bad father too, making Zuko apologize for the fact that Mai hid his attempted murder from her and the fact that her father was trying to put Ozai, Zuko’s abuser back on the throne
And, these are just things that I know off the bat. They are 100% incompatible. Zuko has better chemistry with Sokka, Katara, Suki, Aang, and even Toph than Mai. Toph was a better emotional supporter of Zuko than Mai in her one scene than Mai in the entirety of their canonical relationship together. Zuko understands Aang, Sokka, Katara, and Suki better than Mai-- ever, and vise-versa. They all share similar values and concerns about the world and are able to communicate in a healthy, supportive matter with one another.
Mai is better off with someone like Kai Lo. I will always be convinced that Mai was initially written to be a part of the things from Zuko’s past in the Fire Nation he thought he wanted, but then realized all that glitters is not gold when he left the Fire Nation. Much like Asami Sato in LoK, when Bryke changed their minds because they liked Asami and decided to keep her as a “good guy”, I think they did with Mai, 1.) because they liked her character and 2.) to invalidate Zutara.
They make absolutely no sense together at all whatsoever and have no chemistry. I write this not as a shipping post, but as a plot post. This is bad writing for the narrative and a main character. If Mai existed as a side character, she would be entertaining and well placed, like Ty Lee. Unfortunately, they did not take up the opportunity. And, as much as I loathe to see it, Mai and Ty Lee both existed to further Azula and Zuko’s plots. I hate that for female characters, but unfortunately it was true and when they tried to make them extend beyond side-chatarcterness, that is when Mai became terrible and unlikeable.
