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 first appeared in Uncanny X-Men #229 (May 1988), and was created by Chris Claremont and Marc Silvestri.

Much of Gateway's past remains a mystery to this day, including where exactly he was born and even his name. It is known that he is an Aborigine who appears to have grown up in the Outback.

It is known that he was forced to join the criminal group known as the Reavers after they discovered his powers and threatened to destroy a place sacred to the Aborigines if he didn't follow their orders. They called him "Gateway" in reference to his ability to create gateways between two points in space. Some time later, the X-Men, who had been believed by the world to have been killed in Dallas, Texas, appeared in the Outback and battled the Reavers in their own headquarters. One of the Reavers, Skullbuster, in attempting to escape the fracas, told Gateway that he would release him of all his obligations to them if he helped them escape, which Gateway did.

Afterward, the X-Men took up residence in the Reavers' former hideout, and Gateway began voluntarily using his powers to assist them. Since he seemed to be unable or unwilling to speak, Psylocke used her telepathic powers to communicate to Gateway where the X-Men wished to go. However, the X-Men eventually went back to the United States, and were discovered by the rest of the world to be alive, and Gateway's close association with them ended.

Gateway has not been a contender in any CBUB matches.
