I'm not sure if this Alien Xenomorph building set can be properly called a 'BootLEGO' since it isn't ripping off any specific LEGO set, but it is ripping off LEGO brick designs and the Xenomorph from the Alien franchise so yeah, it's a BootLEGO.
I spotted this sweet Alien set on Alibaba while perusing Chinese BootLEGO minifigures and sets and I think I need one for myself! I don't need a case of 8,000 though, so I will wait until they show up available individually.
I haven't spotted them on eBay yet, but other sets from the Hero Toys or Armored Heroes line are there, so I imagine it's just a matter of time.
The set is Armored Heroes 25268 and made by Ausini, in case you too are hoping to find one for cheap on eBay someday (hopefully) soon!
