gligar is called gliger in japanese. gliger is one letter away from giger as in the artist who created Alien. its even more evident in its beta design
pokedex entries:
>It flies straight at its target's face then clamps down on the startled victim to inject poison. >This Pokémon hangs on to the face of its foe using its clawed hind legs and the large pincers on its forelegs, then injects the prey with its poison barb. >Its tail is tipped by a thick, horrible stinger. To bring down prey, it will first obscure their vision by covering their faces with its body, and then it will use the stinger to inject them with venom. Should be poison/bug but thats too common
