Abraham is a character from the anime Delico's Nursery. He is identified as a supporting character with a distinctive appearance, characterized by long green hair that reaches his waist. He is associated with the antagonistic organization known as Pendulum, a group believed to be behind a series of mysterious murders targeting the vampiric race. The organization is portrayed as a反社会 (anti-social) or rebellious entity operating in opposition to the established order of the吸血种 (vampire race).

A key aspect of Abraham's background is his origin through scientific means. He is the result of repeated human experiments, which have granted him superhuman strength that far exceeds that of a normal individual. This abnormal power is a defining trait, making him a physically formidable presence. In the narrative, he is one of several members of Pendulum, alongside characters such as Kiki, Katarina, Keith, and Julas. These individuals are part of the group's remnants that come into conflict with the main characters, particularly the elite agents of the Vlad Agency. Discussion among viewers indicates that Abraham, along with his associates Kiki and Katarina, remains under the control or watch of the authorities as the story progresses towards its conclusion, suggesting his role as a persistent element of the antagonistic force that the protagonists must contend with. No information is available regarding his personality, specific motivations, detailed backstory, personal relationships, character development arc, or any other notable abilities beyond his immense physical strength.
