I recently got a box of Maschinen Krieger mini kits that sell under the label of "Gacha-nen".  They come in a blind box capsule so you don't know which one of three designs you get.  There are four colors (light blue, yellow, green and brown) and six decals.  Like Pokemon, gotta get em all!  If you buy the whole box as I did, you do get all three designs in all four colors, but the decals are truly random, so I ended up not getting one of the six.

The kits are 1/35 scale injection molded and include instructions.  The decals are waterslide.

I did a quick assemble of two of the kits, the Strahl Demokratisch Republik's PKA H.0 (the one that has an OH-6 Cayuse helo for a body) and a Mercenary "Raccoon" Super Armored Fighting Suit (the one that looks like a toilet).  The pink guy is a "Snake Eye" from a previous Gachanen release.  (Edit:  Pinky scales out to the same size as the curent Fireball SG kit, so my bad!)  The two newer kits feature blanking plates (not yet fitted to the PKA H.0) for their inner legs, something that Pinky did not.

Note that the kits in the photo do not have their detail bits added yet.

For little kits they are surprisingly well detailed and you could go nuts with detailing them further.  The decals include teeny stenciling in addition to unit markings, the only caveat is that no paint/marking guides are provided.  MaK fans will have references to do them "proper", but these little kits were intended to be built any way you want.  Creator Kow Yokoyama even says "There are no rules!" on one of the instruction sheets.
