- Seeker (Micron Booster, 2005)
- Booster ID number: 5
- Seeker uses the Air Military Mini-Con Team Thunderwing mold, transforming into a "flying wing" stealth bomber. He also has a third spinning-blade weapon mode that uses the toy's Powerlinx socket as the swivel point. He was available only as part of the third Micron Booster assortment, in a blind-packed, single-toy box.
- Early promotional images of the set showed Seeker in a different color scheme; less drastically different than the final releases of the other two in the Team, but still notable, being primarily black (or at least a very dark blue) with yellow limbs.
