Thanagarian Snare Beasts are giant spider like aliens from the planet Thanagar. * In the Supergirl (TV) the character Mon-El said that the meat the alien was eating was Thanagarian Snare Beasts. * Kevin Smith's un-produced movie Superman Lives was intended to include a monster called a "Thanagarian Snare Beast" which resembled an Earth spider. The monster was created to satisfy the demands of producer Jon Peters, who insisted that Superman battle a giant spider. Warner Bros. Entertainment, Inc. asked Smith to change it's name so they don't refer to it as a spider..
