Micro-Changer
- Micro-Changers are a subgroup from the brick-based world of Kre-O.

It was only a matter of time before Kreons became so advanced that they were able to transform like their larger counterparts. Transforming Kreons are known as Micro-Changers. Some of them have even gained the ability to join together into Combiners.
Fiction
Kre-O cartoon
A story in the Autobot City News reported that scientists were baffled by the appearance of Micro-Changers. A number of them assisted Megatron in stealing energon Quest for Energon, Part 1 so he could make a grilled cheese sandwich. Quest for Energon, Part 2
Toys
Blind-bagged figures
This portion of the line features individual blind-packaged Kreons. Thankfully however, code numbers printed on each bag allow you to know which figure is inside... or at least avoid buying two of the same by accident.
Preview Series

- Release date: ??? 2012
- This series differs a little from the later waves, and not just because of the smaller (all-badguy) cast. In an unusual backwards move, the tampographs on these figures' chests use only a single color, typically black.
- Crankstart (214510)
- Galvatron (214518)
- Scorponok (214511)
- Spinister (214517)
- Sunstorm (214519)
- Waspinator (214512)
Series 1

- Release date: November 2012

Series 2
- Release date: ??? 2013
- This series replaced the flak jackets used to attach stuff to prior Micro Changers' torsos in prior waves (which most fans hated since it obscured the chest tampographs) with a new simple one-peg "backpack" piece. And there was much rejoicing.
