Picked up Micronus Prime today at Target. Fun little dude! There's a lot going on here.
I haven't read any bio on this guy at all. So based on photos, I saw that he's a smaller robot inside a larger armor. The small guy feels very much like an Armada Micron. In his disc mode, he plugs into the chest of the armor, kinda like a Matrix. The Cybertron artifact plugs into the armor's chest. Cool.
Transforming the armor, that's more of a parts-former, or one of the Weaponizer figures that came out a few years back. Parts convert, but you have to remove the arms, pull the legs off, joined at the hips, then convert the chest into what the Micron would ride, a motored unicycle. The legs converet into the large wheel, and the arms convert into engines (with the fingers as exhaust pipes). Micronus in robot mode can ride the vehicle. Cool. Micronus can also go back to disc form and plug onto the seat of the vehicle.
The armor parts can also be "worn" on other figures in the line with what seem to be now standard 5mm ports. The wheel becomes a shield, torso becomes a backpack, arms become cannons.
He shares a color scheme with fellow Prime Alchemist. They look good together.
I'm glad I found this in store, because I need the receipt to return an extra Fireflight I forgot to cancel at Pulse. They share the DPCI.
