From Gen.Tomahawks' Files :
"X-treme is a new recruit for the Joe team currently training with Alpine and Bazooka in the Rocky Mountains. He has shown a vicious streak and wildness that , frankly I don't know if can be controlled. He's placed himself and others in danger numerous times already yet he and others around him always come away unscathed. He likes living life on the edge , hopefully he won't go over on day. "
