PDHD

Personality:
PDHD is peppy and excitable nearly all the time. He rarely feels pain and negative feelings with few exceptions. He normally has no intention of hurting anyone, but the parasite within him causes him to sometimes get lost in the thought. Said parasite is also the cause for the rare angry and adrenaline-filled outbursts and blow-ups he has. When he isn't being affected by the parasite as strong, he aims to please others, especially humans. He loves them.

He isn't afraid to show any of his physical anomalies, but will cover up so he doesn't scare off other crewmates. He enjoys doing things with others, tasks included, and will zoom through tasks to be able to watch everyone else. (He loves looking through cams. If he can't follow someone physically, following them through a lens will suffice.)

Bio:
Originally a passionate botanist, PDHD found himself on a ship once an expedition dedicated to the study of space vegetation called for crew members. Being a crew full of amateur scientists and students, he fit right in and was easily accepted.

The beginning of his journey was fascinating, and he got the chance to discover and study many species of plants on the field. Everything went well for his team as they sent their findings back to HQ on Earth. His months on the ship and couple planets were very much the same but never mundane until they lost contact with HQ. The ship was still in good shape, but they couldn't call for anyone's attention.

It worried him as days turned into weeks, but he was briefly relieved when another ship boarded their own, only for a group of mechanical beings to gas the ship.

Everything after that point was a blur for PDHD. He was shocked to find himself afloat in space and with a new perspective.
