Serotonin Serotonin was a briefly lived stable in Total Nonstop Action Wrestling . It consisted of Havok , Raven , Kaz , and Martyr . History . On the November 16 , 2006 edition of Impact ! , Kazarian , Maverick Matt , and Johnny Devine appeared with drastically changed appearances , calling themselves The New Movement . Later , through a series of vignettes , they revealed their name to be Serotonin , referencing the brain chemical of the same name that regulates , among other things , aggression , moodiness , and depression — things the Raven character has been linked to since its inception . Raven ' s involvement with Serotonin began differently than with other incarnations of The Flock . Instead of speaking for the group during promos and being around at ringside during matches Raven is only seen after matches , when he comes to the ring to hit the members with a kendo stick , regardless of the result of the match , as part of a program referred to as " torture builds success " . The members drop to their knees and take their licks without complaint , for the most part . The only dissension of being hit was that of Kazarian on occasion , however this was defused by the other members instead of Raven . Serotonin wrestled mostly on dark matches before Pay - Per - Views and lost the majority of them . When wrestling in singles competition , members often took the role of jobbers to more established stars such as Kurt Angle , Sting or Jerry Lynn . Serotonin picked up their first official win at Against All Odds 2007 , defeating the team of Sonjay Dutt & Jay Lethal following interference from Maverick Matt . On the March 8 , 2007 episode , it was announced that Raven had changed their names : renaming Kazarian to Kaz , Maverick Matt to Martyr , and Johnny Devine to Havok . Dissension on the part of Kaz became more apparent during the Lockdown 2007 pre - show , in which Kaz refused to allow Christy Hemme to be attacked by Raven after Serotonin ' s loss to VKM . Serotonin retaliated to this , distracting and therefore costing Kaz in a match against Chris Sabin on the March 31 , 2007 episode of " Impact ! " . On the June 21 , 2007 episode of Impact ! , Kaz turned on Serotonin by costing Raven a match against Chris Harris . On the July 12 , 2007 episode Kaz defeated Martyr and Havok in a 3 - way match to earn a spot in the Ultimate X Match at Victory Road 2007 . Kaz was subsequently attacked by Raven and the remaining members of Serotonin . Kaz defeated Raven in a match at Hard Justice . Bentley was later released by TNA , leaving only Havok and Raven as Serotonin members . Raven made few appearances in the succeeding months , some of which involved Raven and Havok aligning with Black Reign and James Mitchell , who were attempt to destroy Mitchell ' s longtime enemy and kayfabe son Abyss . On the November 15 edition of Impact , Havok was revealed to be Team 3D ' s X Division traitor and reverting to his Johnny Devine ring name , effectively ending Serotonin . While the team was active , they competed in several pay - per - view pre - shows , often in losing efforts . They officially debuted as a team at Genesis 2006 , in a losing effort against the Voodoo Kin Mafia . Serotonin only won twice on a pay - per - view event , albeit in dark matches , defeating Sonjay Dutt and Jay Lethal at Against All Odds 2007 , after Martyr interfered , and Akira Raijin and Brute Issei at Victory Road 2007 .
