Energon
A redeco of the Energon/Cybertron Perceptor component Grindor, Filter transforms into a Cybertronic hovercraft. He was available only in the third Micron Booster assortment, in a blind-packed, individual box. He forms the head and backpack of the combined robot Frenzy.

The same mold is used by Screw.
