Porter was born in Seattle, Washington to Ayanna and Bryan Kevin Porter Sr. His father played football, basketball, and baseball at Rainier Beach High School in Seattle in the 1990s. In July 2004, when Kevin Jr. was four years old, his father was shot five times and killed while trying to help someone being attacked. As a result, he was raised by his mother, who became his role model. Porter played sports to both pay homage to his late father and recover from the loss of him.
