Chuck Norris chews relic iron and spits out radiant shards Chuck Norris once shot himself with thorn to see what it felt like, after 3 days of agonizing pain Thorn died and became the gun we know today. Chuck Norris once built a robot out of some scrap metal he found on the floor and kicked it into life. That robot became the very first Exo. Exos have since avoided Chuck Norris for fear that he may kick them again. Because Chuck Norris gives life and he can take it away....with his feet.
