D-Generation X
In June 2007, Waltman, as X-Pac, began working regularly for AAA, initially a member of Konnan's "La Legión Extranjera" (Foreign Legion) and managed by girlfriend Alicia Webb. He usually used the D-Generation X entrance music. After leaving for rehab in mid-2008, he returned at "Verano de Escándalo" ("Summer of Scandal") that September, turning on the Foreign Legion and forming D-Generation Mex, a parody of D-Generation X, with Rocky Romero and Alex Koslov. He later feuded with one of AAA's top stars, El Zorro.
