Mobile Fortress


 * ''The Mobile Fortress is a fortress which is mobile in the Energon cartoon portion of the Unicron Trilogy continuity family.

"We have destroyed the fortress that once was home to Unicron."

- Optimus Prime is reading from a different script

The Mobile Fortress flies around, sometimes disguised as a comet. It blows up a lot.

It looks like a turd, which is pretty appropriate since it's extruded from Unicron's mass.

When the animators use the wrong reference art, it's perfectly smooth.
