Castagnoli and Ares made their Chikara debuts on 5 July 2003, at the 2003 Tag World Grand Prix, from which they were eliminated after drawing with the SuperFriends (Chris Hero and Mike Quackenbush). Castagnoli returned to Chikara in 2004 as a member of Larry Sweeney's Sweet 'n' Sour International faction. The following year Castagnoli teamed up with Arik Cannon to form AC/CC. The team entered the 2005 Tag World Grand Prix and ended up winning the tournament after Hero turned on his partner Quackenbush in the final of the tournament. Together, Castagnoli, Cannon, and Hero formed the Kings of Wrestling faction. Cannon left the promotion at the end of 2005, leaving Hero and Castagnoli to form a regular tag team. They entered the 2006 Tag World Grand Prix, defeating Equinox and Hydra, Ranmaru and Sumie Sakai, the North Star Express (Ryan Cruz and Darin Corbin), Incoherence (Hallowicked and Delirious), and finally Team Dragondoor (Skayde and Milano Collection A.T.) to become the inaugural Chikara Campeones de Parejas.
