Custom Kreon

First released at the back-end of 2013, the individually-carded Custom Kreons include a number of extra body parts and accessories, many chromed (thus resulting in some extremely tight fits) or translucent (which, when combined with the chromed parts, may end up with stress fractures). The Kreons' "normal" body parts have a metal-flake sheen and more metallic tampographs.

They also come with a customizable "rack" to store their unused parts, though the helmets just kind of sit on the torso's neck-pegs, not secure at all. Returning characters typically have altered and more extensive tampographs across most of their opaque parts.

This series was intentionally produced in smaller numbers than the other series.

Age of Extinction Collection 1

This assortment, using the new unified packaging style introduced in mid-2014, is entirely movie-based, showcasing characters from Age of Extinction. The parts count has been drastically reduced, each kit only having about 30 pieces as opposed to the 40-ish of the prior two waves. They all come with dark green racks.

Another movie-based round. The part count remains in the low 30s. These kits come with brown racks.

Age of Extinction Collection 3

A wave featuring the Age of Extinction Dinobots, making heavy use of the new parts created for Kre-O Dungeons & Dragons, what with the "knight" theme. These kits come with gray racks. These figures primarily saw release in Canada and Hasbro Asia regions. They did however eventually make it to market in the US in very limited quantities through discount stores such as Amazing Savings.

• Release date: November 2014

Robots in Disguise Collection 1

This assortment showcases characters from the Robots in Disguise animated series.

The part count takes another hit, now in the mid-20s, with simpler weapons and no backpacks. No more chromed robot parts either, only a single chromed weapon part. The racks are now in the characters' base colors, and built on a new baseplate piece. This wave does add a 1x1 cylinder to attach to the unused torsos' neck-pegs to keep the unused helmets in place, so there's that. Like the entire 2015 new product line, these use the reworked 2015 style Kreon, making virtually everything from the neck down incompatible with prior Kreons.

Also like the rest of the 2015 line, these toys were not released in the US at first, sold only in Canada and Hasbro Asia markets. However, they began to appear at US discount stores like TJ Maxx and Marshalls in late 2015 at clearance prices.

• Release date: January 2015

Robots in Disguise Collection 1 (2017)

This assortment also showcases characters from the Robots in Disguise cartoons, but uses the bulk-up add-ons that was used from the China exclusive Kre-O Armor Hero Captor line. Each of the sets features three different decos: Armor-up, Blizzard Strike, & Night Strike.

Like the Battle Changers, this assortment was released at Dollar General without any prior announcement from Hasbro itself. As of this writing, only six of the twelve known sets have seen release.

Notes

• The "Autobot Command Center" set includes a Custom Kreon rack/part setup as well, built into the playset.
