If you are talking about the Marvel Comics character, he is a mutant teleporter that is regularly associated with the X-Men. He as an Aboriginal from Australia who does not speak. He can open portals by spinning a bullroarer. He used to teleport the cyborg Reavers from their base in Australia to wherever they commit robberies until they were defeated by the X-Men who took over their Australian base for a time. He's loosely aided the X-Men on occasion since they returned to their usual base in New York. It's been stated that he is possibly an ancestor to the future X-Man Bishop.
