Personally, I don't think Brink is an acceptor until his name is put upon the wall of acceptance, for it to be official.
Name: Subject Delta
Dialogue: Delta crawled along the ceiling, observing the two unsuspecting scientists walked down the hallway, their revolvers pointed either way. They looked all across the hallway, forward, sideways, and even backwards. But not up. Humans rarely looked up. They passed him, and when they weren't looking, he swung down, and stabbed them both. They never look up . . . .
Backstory: Malakotav was always sickly when he was a child, and honestly expected to die of a disease of sorts. So when he got cancer, it was no huge surprise. He had been living in a rundown cottage in the woods of South Carolina, and struggled to get along, and was forced to do some risky things. Him getting a lethal disease was inevitable. He had even decided to live by himself, just in case it was contagious. It was a total shock when the guy who came by to give him food, came by to give him food. He called the hospital, and took Malakotav there to be diagnosed. It was confirmed that he had lethal stages of cancer. The Doctor left the room, and called The Number. In the middle of the night, Malakotav was spirited away to a laboratory, in a pure white room, and strapped to a cold bed. He woke up drowsy, with a large machine over his chest. The machine injected him thrice, and then doctors came to observe the results. His body became stronger, and his cancer cells slowly turned into normal cells. The doctors rejoiced, and left the room. He was the third subject who had been taken in. He was the first one to not turn into a horrible monster. The doctors came again the next day, and injected him with a different set of needles, and his cancer-turned-normal cells slowly became stronger. The doctors left. In the night, his cancer-normal cells became stronger and stronger, and eventually mutated him. He became a humanoid monster, and was vicious. He hated everything suddenly. The doctors came in unsuspecting of his new stage, foolish on their success. They never left. He broke out of his bonds, and went into the observatory room. Inside it was a crate with "Subject Restraint Devices". Within, he found a variety of weaponry, including fours sword-hooks. Which could be attached and removed easily from people with no hands, using the device next to the container. He attached them to his limbs, and crawled out of the room. He was a weapon of stealthy destruction. He hid in the ducts, waiting for the inevitable chaos. It would come soon . . . . . .
Abilities: Has sabers for arms and legs, so obviously is very good at stabbing people. He can go into "spider mode" which allows him to move much faster on all four legs, but is very susceptible to bullet fire. He can walk up walls and on the ceiling by stabbing his saber in the wall and using it as leverage. He can also launch himself forward at fast speeds, and of course swing down from the ceiling and jab people with his legs. He is incapable of speech, and uses screeches and moans as communication with other monsters, and has some sort of telepathy to communicate with humans.
Anything else?: Eh, well, anything concerning my character has been described quite thoroughly, really, so not, not really. Muggles?
