Saiyan

An alien race of warriors from the planet Vegeta. Humanoid with a tail. For thousands of years they traveled the universe conquering planets. A Saiyans body had the ability to obsorb ambient energy and channel & condense it into energy blast either beam or ball form. When they get injured and recovery their bodies heal stronger so every fight they increase their overall power level exponentially. They are born with natural fighting skills: Super speed - so fast an untrained eye cannot see them move Flight by the power of their mind - simple ESP onto their own body to sustain flight Extremely durable body Quick healing Can sense other life forms/power levels Extreme vision, hearing and strength At sight of full moon will transform into a 200 foot tall ape with unstopable power - planet killers Only way to stop is to destroy moon or cut off the tail Let me put it like this...One Saiyan child is strong enough to take over and exterminate a planet the size of Earth.
