they introduced Joey Matthews to become MNM. While in OVW, Nitro and Matthews won the OVW Southern Tag Team Championship once, holding it for over two months. Tag Team Championship reigns (2005–2006) MNM was called up to WWE's SmackDown! roster in April 2005, with Matthews undergoing a name change to "Joey Mercury". They made their debut during Carlito's interview segment Carlito's Cabana, where they interrupted an interview between Carlito and Rey Mysterio, and attacked Mysterio. This provoked a feud between MNM and Mysterio and his partner, Eddie Guerrero, over the WWE Tag Team Championship. Two weeks later, in their debut match on the SmackDown! brand, they defeated Mysterio and Guerrero to win the WWE Tag Team Championship after Guerrero refused to tag into the match. While Nitro and Mercury held the championship, Melina was placed in an angle with Heidenreich. She publicly mocked him and was the impetus for an attack on him by Nitro and Mercury. In July, MNM were scheduled to face Heidenreich in a two-on-one handicap match, but attacked him before the match started. Road Warrior Animal saved Heidenreich from the attack and as a result, Heidenreich and Road Warrior Animal challenged Mercury and Nitro for the WWE Tag Team Championship at The Great American Bash. MNM lost the match and the championship to Heidenreich and Animal at The Great American Bash. The loss of the WWE Tag Team Championship was seen as "bad publicity" by Melina so she introduced Jillian Hall, a storyline spin doctor to repair their image. Hall got them a cover article in SmackDown! magazine, and began to introduce the team before and aid them during matches. In September 2005, Hall left the group to join John "Bradshaw" Layfield (JBL), who had lost a match to Rey Mysterio. On the October 28 episode of SmackDown!, Mercury and Nitro were placed into a tag team title fatal four-way match against the teams of the Mexicools (Super Crazy and Psicosis), William Regal and Paul Burchill, and the WWE Tag Team Champions Legion of Doom 2005 (Heidenreich and Road Warrior Animal). During the match, Mercury and Nitro were able to perform the Snapshot on Heidenreich, to win the championship for a second time. MNM successfully defended the championship against Eddie Guerrero and Batista on the November 4 episode of SmackDown!. In December, they began a feud with the Mexicools, who earned the right to face MNM
