The name Jack has been applied to several Transformers characters.
There are also some real-life Jacks involved with the Transformers franchise.
"Jack" should not be confused with:
- Jackknife, the Air Assault Mini-Con Team jet and Vorpal Saber tip from Armada, released as Jack in Japan.
- Matt Kuphaldt, the artist who goes by the online handle "Jackpot".
