Takeshi Morishima
On February 23, 2007, Whitmer lost to Takeshi Morishima in a match for the World Championship in Dayton, Ohio. In September 2007, he allied with Brent Albright and Adam Pearce to form The Hangmen Three (also spelled as The Hangm3n), which later saw them gain Shane Hagadorn as their manager. While a member of The Hangmen Three, Whitmer challenged for the World Tag Team Championship on a number of occasions with either Pearce or Albright, but was unsuccessful in regaining the title. In March 2008, Albright and Pearce joined Sweet 'n' Sour Inc., prompting Whitmer to leave The Hangmen Three. Later that month, ROH announced that Whitmer had resigned from the promotion, praising his "immense contribution".
