I had simply assumed it didn't count as a disability. In that case I should probably amend the Vorkosigan note to say that he is also a dwarf.
All we knew of was the "iron lung" part for a long time. Though Vader is less "disabled" and more "stone dead without the suit"
Wouldn't Blackbolt of the Inhumans count? He can't speak without destroying damn near everything around himself, rendering him effectively mute.
^ I considered Black Bolt. Though I decided against him, because technically he can speak, many of the Inhumans could qualify as having birth defects.
Waldo, from the Heinlein story of the same name... even had prosthetic arms named aftr him in real life!
I'm not sure Midgets (Normally proportioned people who happen to be very short) would be considered amongst the disabled, just for being Little People. But, yea, Dwarves (Very short people with disproportionate bodies) can be afflicted with body parts that do not support the needed weight of the rest of the body (IE: Legs too small to allow for walking more then a few steps). And, yea, Thomas Covenant is a great favorite disabled hero for me.
Nog from Star Trek Deep Space Nine lost a leg in the final (or penultimate) season, during the Dominion War.
Del Spooner in I, Robot has an artificial arm. Dom Cobb from Inception is in desperate need of a counselor! Worf had major back surgery.
Rimmer from Red Dwarf? Dunno... does being dead count as a disability? lol if not, we can always take into account his personality instead M
