This pair Alien and Predator figures by Grant Masters are only a little larger than minifigure scale, which is remarkably small for such detailed brick-built characters. Even more impressively, though, Grant says that they contain only legal connections–that is, connections you might find in an official LEGO set. There are lots of clever bits, but one of the most amusing has to be Grant’s use of microfigs for the Predator’s legs.
