Maybe they are prototypes, bootlegs or even fake, I dont know. But if mine are fake/bootleg, then all your "prototypes" could be fake/bootleg. In fact, I had sorted them all out and "marked" to throw them away, because i thought they maybe was fake. But what i have learned from buying/selling Lego, is that you should always research first, and then i found this forum. But these "prototypes" were part of a trade, with all the bionicle parts that are currently for sale in my Bricklink store. I still need to sort some new bags, where I know that there is a minimum of 20 new Infected Hau. All the bags on the floor contains each 2 infected Hau - https://imgur.com/a/go2JBlk And what i can see in on this forum, some of you know Lego Galidor Makarr. A never released set, and hart to find actually pictures of. Here is a picture, from when i owned it https://imgur.com/a/WmHMY9H
