He next feuded with Abyss and Brother Runt, losing to the former in a Hangman's Horror match on Impact after the latter turned on him. Subsequent to this, his coverage in major televised angles has dropped considerably. While he was off-air, an alliance was teased between Kazarian, Johnny Devine, and Matt Bentley. On the TNA Primetime Special before Genesis, the three came out in goth, addressing a new movement in TNA. After a loss at Genesis, sporting a new look (often with a mask), Raven revealed himself as their leader, caning the loser of the match. This stable became known as Serotonin. The direction of this stable was very hard to place, although they lost the majority of their televised matches. Regardless of the outcome, Raven would hit the Serotonin competitor with a cane. After a long hiatus, Raven returned to the ring, losing to Christopher Daniels in a First Blood Invitational then losing to Chris Harris after interference from Kaz. On "Impact", Raven came out after Kaz's win over Havok and Martyr and hit Kaz in the back with a Kendo Stick, breaking it over Kaz's back. Raven, Havok, and Martyr then attacked Kaz with kendo sticks. On the July 19 episode of "Impact!", Raven and the rest of Serotonin took on the reuniting Triple X. Raven had very little time in the match and Serotonin lost after Skipper hit a diving leg drop, Daniels hit a Best Moonsault Ever, and Senshi hit a Warrior's Way on Havok.
