The basic upgrade set for the Kreons has been finalized and includes arm and leg extensions. These extensions upgrade your Kreon minifigures into Action Masters with increased articulation at the elbow, wrist, fingers, knees and ankles. The parts also include ports and pegs that are compatible with standard building bricks like legos and kre-o to allow you to build up further on top of them. The parts have been tested in WSF and I find that it sucks up paint like a champ. I'll warn you that it will bleed throughout your parts if you don't seal them first but since I've painted each part a solid color it worked out just fine. I should note that the Optimus upgrade pictured below does not have the basic feet. He is using the upcoming Torso Expansion parts as feet and you can see they give him a bit of height over Blue Streak. Listing on Shapeways In the final phases of testing is a torso expansion set that grants added height and width to the kreon torso as well as an ab crunch. It also includes parts that could be used as a replacement torso for those wishing to have shorter or possibly fembot Kreons. In the later stages of development is an Omega upgrade that will beef up a Kreon to towering proportions. Much more is coming down the pipe as well.
