Kevin Rian is a hero from the Fatal Fury series of fighting games. He made his debut in Garou: Mark of the Wolves. According to the Q&A session of the Garou official website, he is a distant relative of Mary Ryan.
He was voiced by Yo Kitazawa.
Kevin Rian is a high-spirited S.W.A.T. officer of Second Southtown. Kevin's partner was investigating several random acts of murder by a fighter. After several days, Kevin's partner was reported missing and later found murdered in a dark alley. The only detail given to Kevin about the killer's appearance was "a long haired man". Deciding to take care of his partner's son, Marky, Kevin has surely entered the King of Fighters: Maximum Mayhem tournament, as well as he felt that the one responsible would show up. After initially mistaking Terry Bogard for the murderer, Kevin apologizes to Terry but Marky goes missing. With Terry's help, Kevin found Marky peacefully sleeping.
Kevin is a strong sense of justice and is committed to protecting the citizens of Second Southtown. He acts like a tough guy with a cold demeanor, but Marky brings out a warmer, more fatherly side in him.
