The greatest disability feat in ATLA is Combustion man arranging a plan to capture Katara and Toph and clear out the town to get Aang despite not being able to speak.
This neurodivergent (or just physically unable to speak) minor was able to arrange for the sherif to capture Toph and put her in a wooden cage (why would a firebending town even have that lmaoo???) despite her metal bending abilities being fairly unknown outside a few people and then Katara got baited by the reward.
If that wasn’t impressive enough, once Aang and Sokka came looking for them, the entire town square was vacant. This guy is an independent contractor acting outside of national interest and is known for high levels of confidentiality; he definitely did not tell them that he’s hunting the avatar or that Prince Zuko hired him, but by some means he convinced this random towns authority to let him stage his battle in the town. Idek if combustion bending is common knowledge in ATLA or if they started hearing explosions in the distance and thought ‘wtf?’ wherever the town people were waiting.
Anyway, shout out Sparky Sparky Boom Man for being highly efficient at things despite not being able to speak, and also shout out to the town sheriff for being very accommodating to his limitations and ensuring he was able to conduct his work in ways most suitable to him and make murdering several children for bounty as accessible as possible. It was very progressive.
