AND he's a TREE HUGGING HIPPY
Anthropomorphic Dissociative Disorder?
And K.N.Y.F.E. suffers from Debilitating Acronymia.
It's no suprise the box is red.
Ra has split personalities.
Medico has a eating disorder.
Idealist has amnesia.
Expat doesn't have depth perception.
You know... I'm starting to wonder if all Sentinels characters have some kind of disability...
I WOULD say that Absolute Zero has anti-social personality disorder, given how that SOUNDS, but I know that's actually the current name for psycho/sociopath, so.....what's the psychological descriptor for "is a jerk"?
Setback has bad luck!
Expat totally still has some depth perception. Binocular vision isn't everything.
Oh and Visionary's almost certainly got some brain damage.
And is follicly challenged.
Anyone think Unity has ADHD? 
Wait, that's a disability?! 
It is a means by which people are discriminated against, so…sure?
Someone counted The Naturalist being black on the list. If being BLACK is a disability, I'd say being BALD (especially for a young female like the Visionary) definitely counts.
Meanwhile Absolute Zero has Assholeitus (I suffer from it myself; I know the pain!), Bunker has BOS (Blatant Overcompensation Syndrome), Fanatic cannot feel anything from the neck down, Haka's favorite band is ABBA, The Scholar is unemployed, Argent Adept is that annoying roommate who plays too many instruments and keeps you up all night, Omnitron-X is suicidal, Setback is an idiot (the most lovable idiot, but still), and Nightmist is a PARANORMAL INVESTEGATOR! Like, seriously; who actually BELIEVES that stuff!?
sigh Yeah, being hairless, myself, it was meant as a jest, but unfortunately you're absolutely correct. 
Lol, I figured; I met you at the party, but the point still stands. I shave my head, but given what it's looked like the last few times I've been lazy in shaving, I doubt I'd have a whole lot myself 
My boyfriend feels your hairless pain. He had waist-length hair which started thinning, and resisted the inevitable for quite a while before making the leap and shaving it all off (netting £1500 for a cancer research charity in the process).
As much as I like long hair, I think he looks better shaved. It suits him.
Legacy has potential anger management and dysfunctionnal grief
AZ's Hypothalamus can't face temperature change
Tachyon has fast eater syndrome
Fanatic has religious delusions (I agree religious delusion supported by powers, but her background story is a bit too fuzzy as far as being an actual angel)
Nightmist is afflicted with unstable body composion in the presence of shadows (see her bio)
The Scholar is obese, if we're going down the "faces discrimination" route.
Well then, based on discrimination, Wraith is Jewish.
And a good number are female. Not to mention, at least two are gay.
And two are ginger.
Tachyon has fast eater syndrome
She has a highly over-active metabolism. If you don't believe that's a disability, you haven't seen my grocery bills.
