- Sixtrain (Micromaster, 2003)
- In 2003, the entire Sixtrain team was re-released as part of the Micromaster Collection, in individual boxes with a number visible to show which mold was inside each box. For this release, all of the decals from the original version were replaced with paint applications. Moreover, his red feet, hands, waist, and rifle were replaced with black ones. Sixtrain could only be assembled by buying all six compnents individually, he was never offered as a complete set.
- Sixtrain Red Mode (Micromaster, 2003)
- A "chase" combiner, two pieces of Sixtrain Red Mode came per case. Acquiring 5 of the 6 Sixtrain Red Mode members is the only way to provide 2003's regular Sixtrain with the red accessories of his 1990s counterpart.
