- Plug (Micron Booster, 2005)
- Booster ID number: 12
- A redeco of the retooled Cybertron Street Speed Mini-Con Team member Oval, Plug transforms into a modified Saleen S7 luxury car. Available only as part of the fourth Micron Booster assortment in Japan, Plug came in a "blind-packed" box that prevented the buyer from knowing the contents of the box until it was opened.
- The original version of this mold is also used by Flat-Out and Nightscream. It was originally meant to be used for the Energon Mini-Con Brakedown to be packed in with Energon Ultra Magnus, but was ultimately replaced with a different mold set.
