Notes

• The Axiom Gun's design is clearly based on the railgun used by United States Military to destroy Devastator in the film. However, it's presence as a weapon given as a gift by the Autobots contradicts information in the film, where Seymour Simmons says that the railgun was developed by Sector Seven based on studies of Megatron. Also, Optimus Prime flat out refused to share weapons technology with humanity because he could not trust them enough to use it properly.
