While the live-action Avatar: The Last Airbender will remain close to the original show, it could also add more plotlines to further enhance what is already an amazing story. One way the live-action series can do that is by focusing on characters who did not get to shine in the animated series. Even some of Avatar: TLA's greatest characters could use some more backstory or character moments. Particularly, the relationship between major Netflix live-action adaptation.

3 Ozai & Iroh's Dynamic As Brothers

It could make Ozai even more interesting

Despite being brothers and two of the most powerful firebenders in the Fire Nation, Ozai and Iroh don't share one scene in the original Avatar: The Last Airbender. That can be attributed to Ozai not making many appearances throughout the show, as he's hinted as the show's big baddie. The two mention one another at various points. Ozai calls Iroh a traitor for his actions at the end of Book 1, and Iroh questions why Ozai would want Zuko back in the first episode of Book 2, knowing how his brother's mind works. Though neither mentions the other much, it's clear that the two aren't on the best of .

The live-action Avatar: TLA trailer features Ozai, which implies a major change from the animated series. If he is given more screen time throughout the live-action iteration, the show could develop his dynamic with Iroh a little more. Despite Ozai being a power-hungry villain, delving more into his relationship with Iroh could show a more humane side to him. Even with the goals he has, questioning why Iroh would Zuko on his quest to find the Avatar or trying to comfort Iroh following Lu Ten's tragic death could humanize Ozai without compromising his character.

2 Toph's Dynamic With Her Parents

Avatar: TLA Season 2 Could Elaborate On Their Complicated Relationship

Toph's issues with her parents are well-established in her introduction in Book 2, Episode 6, "The Blind Bandit." Toph's parents are overprotective, to the point Toph has to secretly seek out adventures. Sadly, even when Toph demonstrates how powerful she is and tries to show the real her, not only is she ignored, but her parents double down on sheltering her. While Toph's relationship with her parents is complicated, the show doesn't expand on their story much after she runs away.

Toph's dynamic with her parents could be explored in Netflix's Avatar: The Last Airbender, presumably in season 2. The original Avatar: The Last Airbender elaborated further on Toph's side of the matter, including how she had run away before and how, despite her angst towards them, she still feels guilty about running away. However, the live-action remake could delve further into why her parents are so protective and don't trust her despite her skills, perhaps with flashbacks. It could also delve into how difficult it was for Toph's parents to not know where she was in all the time she was gone during the events of Avatar: TLA's Books 2 and 3.

1 Ursa's Relationship With Her Family

Avatar: TLA Could Show What Happened After She Left

Zuko and Azula's mother was introduced in Book 2, Episode 7, "Zuko Alone," which portrayed her relationship with her two children. It's clear that Ursa was a loving mother to Zuko but had a strained relationship with Azula. This obviously played a role in how Zuko and Azula developed as people. After she leaves for mysterious reasons, Ursa is only mentioned a couple of times and appears in Azula's delusion in "Sozin's Comet."

While the comics explained what Ursa did to get herself banished and how she lived her life after her banishment, it would be interesting to see that in live-action as soon as the characters are introduced. If Netflix's Avatar: The Last Airbender has enough time, it should give viewers more elaboration on what exactly happened to Ursa. Doing so can help humanize Azula, who believed her mother didn't love her like she did Zuko. Zuko and Azula are two of the show's most fascinating characters, and learning more about their mother would be a great addition to the live-action remake.
