Master M

Peter Moon, better known by his alias Master M, is a veteran of the Last War of the Kings in Magid and the father of Cody and Maro Moon.

Prior to The Kyoto Ordeal
Peter was recruited by the Creator for an unknown reason to help fight against Pappade Klauss during his conquest of Magid. He fought under the army of the Metal King, and despite his skill with a sword the planet was doomed to fall into the hands of Klauss. The kings entrusted Peter with a fraction of each of their powers, as well as the sword of the Metal King which would later be known as the Sword of Magid. Peter was asked to return to Earth and guard the powers of Magid in the event that Klauss should ever discover that the kings had sealed the rest of the element powers away. Disgraced, Peter could not return to face his children. He instead went to Kyoto, where he planned to live his life quietly in shame.

The Kyoto Ordeal
In December of 2004, Peter discovers Adam Evans in Kyoto, mistaking him for the Creator. After speaking with Adam, he learns that Magid has taken a turn for the better, even if her king had left to deal with the problem in Kyoto. Peter, referring to himself as Master M, decides to train Adam how to use the powers of the elements to defeat his doppelganger. Adam is quick to learn, despite only having half of the powers at his disposal, and defeats Peter in a duel. Peter bestows unto him the Sword of Magid, asking him to use it well to defend Magid.

Peter later appears at Nijo Castle following the fight between the Creator and The Baggins. He realizes that the Creator used his son as a means of fighting The Baggins and sends him away to help Adam. Following the battle, Master M reunites with Cody and the two return home to Seattle. Prior to his departure, Peter warns the Creator that Adam now has considerable power and is a threat to the Creator.
