All my characters in my comic are disabled, actually.
Anselm/Topher/that lot - are first of all a system. theyre autistic, with other stuff going on too. also because of their situation (raised from the dead and shit) they have little to no immune system or healing factor and without their superpower would probably die instantly.
moran - has bpd, and is autistic. she often goes nonverbal.
david - has ptsd, and possibly hpd
peter - has multiple learning difficulties as well as autism, and has npd and hpd. hes also a survivor
maria - is autistic and has adhd
darwin (the one who calls himself remus lupin in comic) - is hard of hearing, autistic, and psychotic.
novex - is mobility disabled and uses a cane at all times, and a wheelchair for long journeys. xes also asthmatic and extremely short sighted. xes autistic and dissociative.
theyre all disabled because, well, i am. so why not?
