Of all the possible classes of Functionism, set out and labeled according to the Grand Cybertronian Taxonomy, the Ornament class is possibly the rarest seen of all. So much so you might even think the Ornament class was just something made up one day as a cheat. But it isn't. They really exist, their seldom-seen alternate modes fulfilling whatever role Adaptus designed them for, probably brightening up a room or something.

The Functionist Council would never lie about things like that.

After several thousand more tests they gave up, and decided to create the entirely fictional ornament class, dubbing Rung its only member. Little Victories
