From 2006 to 2008, Ron Killings was a member of the Foreign Legion, making occasional apperances in the ever revolving roster of outsiders. Killings was brought in thru AAA's relationship with TNA at the time, and appeared with the promotion after both AAA and Killings stopped working with TNA. Killings appeared more than most US based Legion members, but did not have any notable feuds or rivalries during this time in AAA. His most noteworthy moment was accidentally breaking Laredo Kid's leg during the 2007 Torneo Antonio Pena gauntlet match.
Killings finished up with AAA in March of 2008. He was listed as working two weeks more, thru Rey de Reyes, but had previously signed back with WWE and was pulled from his remaining outside matches earlier than expected.
