Nunzio, threatened to bring in his "family" to gain revenge on Rikishi, after being attacked. The next week, Chuck Palumbo and Johnny "The Bull" Stamboli joined with Nunzio to form the Full Blooded Italians and attacked Rikishi. They initially gained little success, but later had brief feuds with a number of notable wrestlers and tag teams, including Los Guerreros, Chris Benoit, Rhyno, and the Acolytes Protection Agency (Faarooq and Bradshaw). The F.B.I. was also used by Mr. McMahon to attack The Undertaker and by Jamie Noble to attack Rey Mysterio. When the group turned into fan favorites, they grew in popularity.
