Jack Norman was the head of the bioterrorist group Il Veltro. Believing that the Earth had become decadent and sinful, Norman devised a plan to use numerous B.O.W.s to create terror to make the people realize their sins and corruption. The group, and Norman himself, were secretly financed by FBC head Morgan Lansdale.
Lansdale provided Norman with the t-Abyss Virus and means to disperse it over the recently built aquapolis of Terragrigia, through the use of three cruise ships, the Queen Dido, Queen Semiramis and Queen Zenobia and various UAV systems.Though Norman believed Lansdale shared the ideals of Veltro, he suspected Lansdale was merely using the group as a pawns to further solidify his position of power within the government, and he kept video logs of all of their interactions on his PDA in event Morgan would double-cross them.
After the destruction of Terragrigia, Norman's fear came true and his group were betrayed by Lansdale, and were trapped on the sinking Queen Dido. Surviving in an unflooded area of the now biohazardous ship. Norman and the last surviving members of Il Veltro counted down the days of their containment in blood on a wall.
Nearly a year later, an F.B.C. armed forces team that included Dario Barioni were ordered by Morgan to obtain the video recordings of Lansdale's deals with Il Veltro, but were killed by Norman, who had survived by desiring nothing more but revenge. This skirmish ended with only Jack Norman surviving. Seeing this, Norman recorded one final message in his PDA, declaring that Lansdale would never obtain the recordings before he injected himself with the t-Abyss Virus.
By this time BSAA agents Jill Valentine and Chris Redfield boarded the sunken ship and found in an unflooded are, the last surviving member of Il Veltro. Driven mad by the loss of his friends and by watching them mutate, he took an large dose of the t-Abyss virus as soon as they found him. This caused him to transform into a creature known as the "Ultimate Abyss" with the ability to create powerful illusions, move so fast that he seemingly teleported and to summon duplicates of himself. After a long battle, he was killed by the two agents. Before the ship was caught in fire,dying Norman expressed his relief that he could finally be at peace.
"Done... everything finished... finally... I can die... I... can die..."
Ultimate Abyss appears as a large humanoid figure with aquatic traits. The creature's left hand is noticeably bigger and possesses sharp claws that serve as its main weapon. Two fins sprout from its back, with a bulbous growth between them. Upon attacking, a flap on the right side of Abyss' chest will open to expose its large heart.
Its original Tyrant-like face can be retracted in order to reveal a singular eye, similar in appearance to that of the Draghignazzo.
