Killer Death Machines

Killer Death Machines was a professional wrestling tag team consisting of Jessicka Havok and Nevaeh. They were best known for their time in Impact Wrestling. They also competed as a team in the independent circuit most notably for Shimmer Women Athletes and Rise Wrestling, where they are the reigning and longest reigning Guardians of RISE Champions in their first reign. The team would also compete for Women of Wrestling's sixth season as Monsters of Madness in 2019.
The team would also compete in Impact Wrestling from 2020 to 2021 until the team disbanded after repetitive losses as Nevaeh turned on Havok. This would lead to Havok defeating Nevaeh and Nevaeh leaving Impact shortly after.
