- Wrench (Micron Booster, 2005)
- Booster ID number: 6
- Wrench is a redeco of the Mini-Con Incinerator, transforming into a Cybertronic drag racer. Available only as part of the fourth Micron Booster assortment in Japan, Wrench came in a "blind-packed" box that prevented the buyer from knowing the contents of the box until it was opened.
- Many fans place Wrench as the Mini-Con partner of the Cybertron Autobot Blurr, as Wrench's mold is the gang-molded partner to the original mold used to make Blurr. However, the packaging for the assortment Wrench 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. Even though Wrench has Velocitron-style clear tires, his packaging states he is of Cybertron origin.
