Along with his close friend, Barbara, Cislo formerly resided in Goodwill Ridge, one of the four premium farms. He is shown to have had a happy childhood there, until he and Barbara were shipped out and sent to an experimental farm called Lambda 7214. Cislo was tested on with numerous experimental procedures, which resulted in his powerful strength.
After being held in Lambda 7214 for around four years, Norman, under the alias of William Minerva, rescued Cislo and the other victims who were experimented on in the plantation, as the latter was burned to the ground. Finally free from Lambda, Cislo was eternally grateful for Norman's help and began addressing him as "Boss" as he serves as his underling in the Paradise Hideout.
Cislo is a stout young man with short black hair patterned with a white "X". He has a very toned, muscular body. He wears a tactical vest with a black shirt underneath, along with black gloves.
Since Cislo has been experimented and tested by Lambda workers, he has a deep hatred of demons and does not hesitate to kill. However, he has a goofy, kinder side and he's always ready to help and care for his friends.
Weapons and Abilities
Cislo fought a group of demons guarding a factory farm with a pair of Nunchaku, a traditional Eastern weapon used in martial arts.
Barbara and Cislo are close with each other, as they both are part of the Norman's Lambda group and came from Goodwill Ridge. The two both hate the demons with a burning passion and want to destroy them. They have a deep sympathy for each other and Cislo tends to keep Barbara from getting too upset.
Much like the other children from Lambda, Cislo thanks Norman for saving his life and is very loyal towards him.
