Botanica's ship

This ship was of unknown classification, but it appeared physically identical to the Omega Delta.

Beast Machines

This ship carried Botanica and her crew to a world of sentient plants, and was used by Botanica to return to Cybertron after receiving a distress signal. The ship was shot down by Cybertron's automated defenses, and then destroyed by the Grand Mal.
