A peculiar child with a peculiar name. 17 was introduced in to our otherwise natural system by outsiders for less than positive purposes. 17, however, didn't follow these directions and instead acted heroically.
Now that we live a relatively safe and enjoyable life, 17 has developed in to a fun loving little boy. He has a great sense of humor, loves to make new friends, and has a fondness for Pokemon.
Where 17 came from, he is considered rogue and has kept his peculiar name, and taken on the nickname of "Rogue", as an affront to those who once controlled him.
