MetaBall Studios lines up sci-fi’s aliens on a single scale, from Star Wars’ Grogu at knee height to Galactus looming as a planet-sized giant, with xenomorphs, Predators, and dozens of lesser-known creatures stacked in between. Every figure is sourced and labeled — white text cites a source, yellow text is the studio’s own estimate — down to sizing Midi-chlorians like mitochondria at the microscopic end. Less a comparison than a cast list for the entire genre.
