X-Ralien

X-Ralien is an alien that appears in the series Ben 10: The Evolution. When Victor first tried him out, he was dubbed Bonehead, but it was then truthfully X-Ralien.

X-Ralien can stretch out his arms and legs and make them go out however far. He can also take off any of his bones and put them back on without any problems. Like Swampfire, he can have an empty part in his body with any pain.
