Ok then.
Real Name: Alan Cruise
Nickname (what everyone else calls him): Archer
Former Home: Phoenix, Arizona
Weapon of Choice: Longbow
Since his arrival, only the five children knew him. But soon after he made his first stand at defending the Great Valley, the children's families know of him as well. So right now, no one else other than those mentioned above knows he exist.
So that's all I have for him. I may add more if the need arises.
