Raven won a House of Fun match, on the August 9 episode of "Impact!". He teamed with Robert Roode and James Storm against the team of Chris Harris, Rhino, and Kazarian. Raven lost to Kaz, who had rebelled against him, at Hard Justice despite having the remaining members of Serotonin involve themselves in the match. He then issued a challenge to Abyss and Rhino at Bound for Glory. Abyss later had Black Reign added to the match and made it a Monsters Ball. Raven briefly formed an alliance with Havok, Black Reign, Judas Mesias, and James Mitchell with the purpose of defeating Abyss. At Bound for glory, Raven would go on to lose the match after Abyss gave him a black hole slam on to tacks and glass. On the November 15 episode of "Impact", Havok was revealed to be Team 3D's X Division traitor, effectively ending Serotonin. At Turning Point, Raven substituted for Rhino in the "Match of 10,000 Thumbtacks" and teamed with Abyss to defeat Black Reign and Rellik. Raven was officially released from TNA, and his profile was removed from the roster on March 7, 2008.
