Marvel: Trans-Dimensional Gateways

Gateway
Gateway is in tune with the spiritual force of his people that allows him to create teleportation "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 teleportation 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.
