Balrog

Balrog was once a great boxing champion and prize fighter. He was banned from boxing for permanently injuring his opponents and killing one (as well as his illegal maneuvers, particularly his headbutt), so he joined the Shadaloo criminal organization, and worked his way up from the bottom, eventually becoming M. Bison’s enforcer. While running errands for Bison (Vega in Japan), he killed Dhalsim’s elephant with a single Gigaton Punch. In one mission, Balrog was sent to terminate Birdie. Although he did not know why, Balrog went anyway. Birdie told him about the Psycho Drive, and Balrog agreed to help him find it, thinking he could make money from it. When the Psycho Drive exploded, Balrog realized that he had not been paid recently. When Bison was killed at the hands of Akuma, ownership of Shadaloo was transferred to the former prize fighter. Unfortunately, he ended up running the entire organization into the ground in no time. After the fall of Shadaloo, Balrog was back on the streets, working menial jobs (such as casino security, as seen in his Street Fighter IV intro cutscene). However, when Bison makes his return with the construction of his new body, Balrog is immediately brought back into the organization.
During the events of Street Fighter IV, after Balrog is re-recruited into Shadaloo, he manages to make his way into the S.I.N. building (along with fellow agent Vega). While looking for “treasure” (possibly anything he could sell), he stumbles across a young, bandaged child begging for help. Balrog is resistant, until a mark in the shape of the Shadaloo symbol begins to glow on the child’s hand. Realising the child could hold some valuable secrets, Balrog takes him away (saying along the way ” This must be my lucky day”.
