Rafael "Rakin" Knittel was born in Salvador, Bahia, Brazil. He lived in Switzerland for two years, and in Los Angeles, California in the United States. His first video game was Counter-Strike 1.5, which he started playing when he was seven years old. He also played Heroes of Newerth and was the captain of one of the top Brazilian teams prior to switching to League of Legends.
Rakin joined Call Gaming in May 2014, his first competitive League of Legends team. With them, he qualified for the Spring Expansion Tournament via the ranked 5's ladder but then was eliminated in the first round by Team Coast. On December 22nd, Call Gaming parted with their Expansion roster and Rakin left the team.
After leaving Call Gaming, Rakin formed Team Amine, which eventually competed in League One; partway through that tournament, the team renamed to Cerberus eSports. After a seventh-place League One finish, Cerberus entered the AlphaDraft Challenger League, and the roster was acquired by Noble eSports. On April 26th, Rakin retired from competitive play in North America. In May, Rakin became a substitute for Counter Logic Gaming Black.
