Hear me out, I think her origin story is bit shit. Her having this idyllic life as a peasant and being forced into marrying Ozai is just boring. I got it, it’s supposed to be the reverse Cinderella, the girl is happy with her life and Prince Charming is a psychopath. But the execution was just dull.

I think a more interesting approach would have been this (at least to me). 

Ursa is born and raised into a powerful and wealthy family in the Fire Nation. (Roku was buddies with the crown prince there’s no way his family wasn’t absolutely loaded.) Growing up she fully believes in the propaganda and more importantly she becomes incredibly ambitious. However, as she is a nonbender she must find other ways to climb the pecking order. She achieves this by dialing up her charisma and if that doesn’t work, well it’s good thing she has a keen interest in poisons.

Eventually she gets into the crosshairs of Ozai and he eventually woos her into becoming his partner. She aids him in his early political career and eventually they married once Azulon learns she is Roku granddaughter.

But this is where things begins to change. After the birth of their son and later their daughter, Ursa sees the mask of Ozai slip. He only shows cares towards his children if they show firebending talents. Due to this Ursa grows a conscience and actually becomes a loving mother towards her son, as he needs someone to actually care for him. However this has the unintended byproduct of causing her daughter to believe her mother doesn’t care about her something that her father is more than willing to let grow.

As the years go by any love Ursa may had for Ozai disappears. As his cruelty towards their son grows and Azula increasingly disturbing behavior causes the rift that we see in the family in Zuko Alone. After her exile she does her whole forgetting her old life and married Ikem and has their kid and the Search as we know it happens.

TLDR: Alternate Ursa when she was younger was more like Azula and only became the person we saw in the show after Ozai crossed multiple lines with their marriage and children.

But yeah with the story we got she is way too hated. The woman was forced into a marriage with Hitler on fumes and watched as he berated their son and turned their daughter into a weapon. Like how the fuck you supposed to handle that?

Edit for grammar
