But, before I get started, you have to know that he was raped by older girls and women, abused by scientists and experimented on in his childhood. I'm going to mention these things later and I thought that I might as well say it now.
PSYCHOLOGICAL PROBLEMS-He has D.I.D (Dissociative identity disorder). Due to being raped and abused repeatedly in his childhood, he developed this disorder. He has two alters: Venture and Blitzy; Venture is pretty much the personification of all the dominance and assertiveness that was stripped from him, he tends to "take control" when Blitz is angry or frustrated and Blitzy is the same, but he represents his childish wonder and innocence, he "takes control" when Blitz is sad or scared. You can tell which one's taking the reigns at any point because Venture's abrasive, cold, agressive and hot headed; and Blitzy's very childish in the way he acts and communicates and he gets easily upset and scared .
-He can't eat more than a few bites of food per meal. The scientists put a type of poison in his food when he was little. This poison causes vomiting if too much is ingested. Blitz used to be a chubby kid and the scientists thought that doing this would solve the problem. And the poor thing only managed to take a few bites before he started vomiting and he only eats that much as an adult due to his paranoia. Now he has to take vitamins and supplements to make up for this lack of nutrition.
-He has extreme Gynophobia (fear of women).
-He associates sex with pain and he hates even the idea of it. His boyfriend is starting to bring him out of that mentality.
-He has extreme self-worth issues.This is mainly due to the abuse and experiments, making him think that he's nothing more than a lab rat and that's all he's worth. He's starting to forget about them now tho.
-He shows borderline suicidal behaviour when he starts falling back into the previously mentioned issues.
PHYSICAL PROBLEMSNOTE: most of these were caused by the experiments that were performed on him, unless otherwise specified.
-He has Asthma.
-He has broken bones that never healed properly. His left femur healed pinching a nerve, causing extreme pain and having him walk with a limp.
-He's mute due to having his tongue cut out. This happened during one of his rapes because he "screamed too much". He has to either write or use sign language to communicate because of this.
-He's deaf because his eardrums burst, but now has an implant that brought back his hearing.
-He's covered in scars from top to bottom.
-He's blind in his left eye.
-He has an extremely weak immune system. Even a mild cold can make him bed-ridden for days.
-He has a lot of allergies. Going outside in pollen season is pretty much a death sentence.
-He has horrible depth perception.
-His eyes, ears and skin are extremely sensitive.
-He has migraines. But he doesn't suffer from the headaches very often, only when there's an extreme and rapid change of pressure, like if he goes on a plane; very loud noise and some other things. (when he was diagnosed with migraines at age 7, the scientists started experimenting to see what would cause him to suffer the headaches)
And that's it! ^^ Everything that's wrong with Blitz both physically and psychologically ^^
