Anoa'i made his first venture into wrestling in July 2010, when he signed a developmental contract with World Wrestling Entertainment (WWE) and was later assigned to their developmental territory Florida Championship Wrestling (FCW). He debuted on September 9, 2010, using the ring name Roman Leakee (often shortened to Leakee), in a loss to Richie Steamboat in a singles match. Further losses to Idol Stevens and Wes Brisco ensued, before he gained his first win on September 21 over Fahd Rakman. He continued competing in FCW throughout the remainder of the year, wrestling mainly in tag team matches. On the January 16, 2011 episode of FCW television, Leakee was a competitor in a 30-man Grand Royal, but was eliminated. Later in 2011, Leakee formed a tag team with Donny Marlow and the pair unsuccessfully challenged Calvin Raines and Big E Langston for the FCW Florida Tag Team Championship on July 8.
