- (Note: Many fans place Clamp as the Mini-Con partner of the Autobot Longrack, as Clamp's mold is the partner to the original mold used to make Longrack. However, the packaging for the assortment Clamp was available in does not give any of the Mini-Cons a faction affiliation, so there is nothing to officially say who these Mini-Cons work with, if anyone.)
- Clamp (Micron Booster, 2005)
- Booster ID number: 4
- Clamp is a redeco of the Mini-Con Refute, transforming into a Cybertronic vehicle with a large forward gripper claw. Available only as part of the fourth Micron Booster assortment in Japan, Clamp came in a "blind-packed" box that prevented the buyer from knowing the contents of the box until it was opened.
