Rock Howard/Story

History
Rock is the son of the most noteworthy crime lord in Southtown, Geese Howard. Although he knew of his father's existence, he grew up living a modest life with his mother in a small apartment. He often wondered about his father and was excited at the prospect of someday meeting him. When Rock was seven, his mother contracted a mysterious disease and he tried his best to nurse her to health. As her illness worsened, Rock went to Geese Tower and met his father for the first time in his life. Though the boy pleaded for medical aid and told him that Marie desperately wanted to see him, Geese would have nothing to do with the matter and sent him away. Marie died the same night and Rock has had a grudge against his father ever since.

Real Bout Fatal Fury
A year later, Rock meets Terry, who finally settled his vendetta against Geese. Rather than hate his father's enemy, he felt a complicated mix of loneliness and joy knowing that his father died. Since Terry left the scene soon after, the boy followed him and attended his street fights. Rock angrily charged at him once after learning about his father's death. After their scuffle, Terry quietly accepts him and they begin their travels together.

Garou: Mark of the Wolves
As the years go by, Rock becomes a formidable fighter, due in no small part to having been trained by Terry. Approximately ten years after Geese's death, Second Southtown was established. During this time, a new King of Fighters tournament arose, dubbed Maximum Mayhem, to which Rock decides to join to search for his purpose in life.

By the end of the tournament, Rock finds his final opponent is Kain R. Heinlein, who reveals himself to be both the host and Rock's uncle. Upon winning, Rock discovered that the tournament was orchestrated by Kain to bring Rock to him. Kain, aware that Geese Howard's will held presumably valuable secrets but unable to discover them without assistance, won Rock's aid in working through the document by offering information regarding Rock's mother — whom Kain claimed was still alive. Terry accepts Rock's decision to become Kain's new partner, with Rock promising to return.

In his development blog for KOF: Maximum Impact 2, Ureshino states that he doesn't know about Rock's mother or the true inheritor of Geese's legacy, but hints that it would most likely conflict with Terry. Rock's scenario in this game explores his personal take on the character's actions in the yet to be released Mark of Wolves sequel.

The King of Fighters
''Rock's life in this timeline seems to mostly be based of his Fatal Fury counterpart up until Garou: Mark of the Wolves. However, it is implied that Rock's ending in Garou MOW did not occur in this timeline.''

In this timeline where his father Geese is alive, Rock is growing up during The King of Fighters XIV tournament under Terry's wing. His last appearance as a child is when he and Terry met one of their friend Joe Higashi before recruiting Tizoc for the 2003 tournament.

Shun'ei Saga
During the events of SNK Heroines, after XIV tournament, Terry was having nightmares on being turned into a woman by a sand fighter known as Kukri and being pushed by Rock off the Geese Tower in his original male form, after Geese refuses Terry's help and allows himself to fall. Terry awakens faceplanted to the floor, while Rock is done cooking breakfast and calls him to eat.
