Gateway is a fictional comic book superhero in the Marvel Comics Universe, an Australian mutant with the ability to teleport objects and people from one location to another. He is considered an unofficial member of the X-Men.
Gateway is in tune with the spiritual force of his people that allows him to create teleportational "gateways" from one location to another. Gateway creates these warp tunnels, which can traverse both time and space, by whirling his bullroarer over his head. Gateway somehow causes a burning fire to appear before him when he creates one of his gateways, though the role that the fire and the bullroarer play in the creation and functioning of the gateways is unclear. The gateways can be used for both observation and transport. The exact limits of how much mass can be transported is yet to be revealed.
There are no known limits to Gateway's teleportational range. He has, for example, transported the X-Men from Australia to the United States and back using his powers, as well as transporting them trans-dimensionally to another Earth. He also opened up gateways that observe past events, such as the one that allowed the feral X-Man Wolverine and the ninja named Elektra to learn the truth behind the powerful psionic being known as Onslaught. He has transported Wolverine to the past, 1937 Spain, and returned him to the present.
Gateway also possesses psionic abilities that allow him to communicate with telepaths . Gateway apparently prefers this method of communication over the verbal method, having spoken out loud only twice during his association with the X-Men. It was this ability that allowed him to communicate with the X-Man Psylocke to ascertain where and when the X-Men wished to be teleported, as well as knowing when they wished to return or what their exact location was at the time they wished to come back. Gateway also once spoke to the telepathic Generation X member named Chamber psionically, as well as regularly communicating psionically with the St. Croix twins.
Gateway is skilled in wilderness survival and the lore of his people.
