Here are twenty Legends characters to consider creating content with for this event! This is just a highlight list of the more major characters/characters I particularly like/unique characters. There are many more, and I provided some links you may find helpful for a deeper search!
I kept the list primarily to physical disabilities just because those are easily defined on page whereas neurodiversity of fictional characters can be more open to interpretation. For example, I would say based on the Jedi Quest books that Ferus Olin probably has an anxiety disorder. But it is not something that is explicitly said, so it is up to interpretation and other people may see it differently than me. This is in contrast to something more explicitly defined, like the fact that Tenel Ka is an amputee.
Cay Qel-Droma - a Jedi of the Old Republic in the Tales of the Jedi comics lost his left arm in battle and later received a prosthetic.
Bao-Dur - a Zabrak Jedi of the Old Republic in the second Knights of the Old Republic game lost an arm during the Mandalorian Wars and later received a prosthetic.
Zule Xiss - a Falleen Jedi padawan of the Clone Wars era in the Republic comics lost her arm to Ventress in the same battle that claimed the life of her Jedi master, Glaive. She continued to fight for the Republic with a prosthetic arm until she was killed in the Battle of Jabiim.
Tholme - a Jedi of the Republic/Clone Wars/Early Empire era in the Republic comics, loses his right leg and left eye during the Clone Wars. He receives a prosthetic for both, and uses a cane to walk after this occurs.
Tenel Ka Djo - a Jedi of the New Republic era becomes an amputee in the Young Jedi Knights books after a lightsaber malfunction. After discussion with Luke about his experience as an amputee, she chooses not to receive a prosthetic and learns to adapt to fighting and living with a single arm.
Tionne Solusar - a Jedi of the New Republic era has a prosthetic arm and leg. She was one of Luke's original students at the New Jedi Order academy.
Nawara Ven - a pilot of Rogue Squadron lost a leg below the knee in an engagement and returned to their previous career of practicing law after receiving this injury and prosthetic.
Gavar Khai - a Sith of the New Republic era in the Fate of the Jedi books lost his arm in battle with Luke Skywalker and had it replaced with a prosthetic.
Wolf Sazen - a Zabrak Jedi of the Legacy era in the Legacy (2006) comics has a prosthetic arm. He is closely tied to the Skywalker family, as Kol Skywalker's padawan and Cade Skywalker's master.
You can find a longer list of characters with prosthetics here, a list of characters with lost limbs here, and of course Luke and Anakin fall into this category as well!
