Gates vary: lifting barriers; normal soft skinned gates, which can be clad as an extension to the cover-from-view screen, strengthened gates which can resist small arms or projectiles; blast and vehicle bomb resisting gates. Gates are designed for the specific location and threat. They are most effective if used in pairs as lock gates; or in a labyrinth. They are best if covered by Sangars. They may be used in combination with blast walls or dead stop barriers or both.
In the fictional DC Universe, Ti'julk Mr'asz, codename Gates, is a member of the Legion of Super-Heroes. Like all natives of the planet Vyrga, Gates has a largely insectoid body. He is also noted for his strong political views, tending towards communism, socialism, and anarchy.
