Xantium (G1)

The Xantium is an Autobot ship in the Generation 1 continuity family.

Does this make it a Wrecker?

The Autobot battlecruiser Xantium transports the Wreckers from mission to mission. It looks like it transforms into some giant robot.

Notes

Don Figueroa said that the Xantium design is based on "Stronghold", a character from his old Macromasters fanfic comic. He also said, though, that if it ever transforms into a robot it will look a lot different.

On the other hand, Chris Ryall has said that the Xantium isn't a Transformer, though this statement could be interpreted in a few different ways.
