Henry is diagnosed with Mixed Delusional Disorder. it is a category of Delusional Disorder in which the patient displays more than one trait. Somatic Disorder being the one that makes a person think that they have something physically wrong with them, which includes delusional parasitosis; a belief that bugs are crawling on/under the skin  *don't play along, it will only make the delusion seem more real and can cause problems* along with either a  rash, bruises, broken limbs *he will act as if he can't use a body part*, bleeding, cuts or skin discoloration.

Persecutory Disorder makes henry believe that someone or something is out to harm him, spying on them, stalking them. Having this disorder can affect him more often than not since it would bring down his mood, get angry and maybe hostile towards others. It's best to soothe Henry with medicine, or attempt to talk to him so he will be able to calm down long enough to have his injections, which are always located in his display cage. 

if you can handle his sudden behavior changes...try him

Bio:
Henry had lived a pretty normal life up until he was 8 years old, he had his mom and dad, along with an twin brother Jack and his new half-brother; Kazuya who was a year younger than the twins. Kazuya was brought into the family when the twins were 6 years old, since Kazuya lost his family. the three kids were loved equally and there were never any problems, unless counting Henry being mean to Kazuya and Jack being nice to him whenever Kazuya was upset or hurt. It was until one morning, when Henry went out with his mother to the store, things were fine up until Henry began to act strangely. He seemed to be very cautious about everything around him and was even convinced that someone was out to get him.
He didn't tell him mom since he thought that just maybe, he was just imagining things, but his fear only grew worse day by day. Every day at school, he was always guarded and felt someone nearby but whenever he looked, there was no one there. his friends noticed his behavior and commented on it and henry would tell them but they would just think it's his imagination getting the best of him.
This went on for a while until he told his parents about the situation. naturally, they got worried, so every day, either the mother or father would walk to school with him and then take him back home at the end of the day. But it didn't help. he still felt like he was being watched, it eventually got so out of hand that henry began to lash out at those who didn't believe him. No one understood what was going on with him, and those who tried, were left confused about it all.
Eventually, the family decided to take him to see a counselor to discuss his fears and the counselor told them that Henry was just being paranoid or perhaps feeling the presence of spirit. since it was common for children to be more connected to the spirit world, it was then noted that Henry may just have been afraid since he didn't know what was happening.
Henry managed to come to terms with the fact that a spirit was nearby but wasn't going to hurt him and after 6 months, henry no longer felt scared. But then when Henry turned 9..his brother had passed away in a car accident.. he had gotten run over when he ran across the street to get his ball. For the longest time, Henry didn't want to talk to anyone or see anyone, and even his mother acted strangely, she even began calling him 'Jack'. Every day, he would be called Jack by his mom, and since his father wanted her to feel better, he began to do the same, so at home he was Jack and at school he was Henry...but within 3 weeks..Henry started acting like Jack. He mimicked his brother, from what he ate, to what he would wear, to what toys he played with. Even if he was still Henry at school, he stopped responding to the name 'Henry' altogether. The teachers thought he was still in mourning, so they gave him space, newer teachers who weren't informed accidently call him Jack and he would respond to them, soon the teachers were confused about the situation.
The parents began to worry and whenever they tried to treat him as Henry he began to lash out at them, yelling out 'I'm Jack!' so they took him to see a counselor who began treatments on him, and concluded that he had Delusion Disorder. After about a year, Henry went back to normal but still recieved couseling from time to time. When he turned 11 years old, his disorder kicked in and he acted as if he was a boy from another school. Only this time, he was close to killing the other child, saying the words 'The fake has to die'. Luckily, the two were found and Henry and the boy were taken to two hospitals, where Henry remained until he was 15 years old.
