Galvatron's ship

As enigmatic as its owner (who is an alternate-future version of himself in a splinter universe) Galvatron's ship is a convenient way for him to get around when the need arises.

Marvel The Transformers comics
Galvatron waited in his ship while his mind bug penetrated the Ark's defences and probed the deactivated Autobots' dreams. When the mind bug ceased transmitting, he boarded the Ark to investigate but was defeated and imprisoned by the awakened Prowl, Ironhide, Sunstreaker, Wheeljack, and Silverbolt. His ship's eventual fate went unrecorded.
