Baron Au'Mydas Bayconn is a petty villain in the AdventureQuest universe. Affiliated with King Alteon the Good. He is primarily characterized by his greed and his willingness to do whatever it takes to hang on to the gold he has. In the grand scheme of things, though, he is purely a jerk, and does few things that can be considered to truly hurt people in general.
Bayconn is the villain of the 2010 and 2012 Lucky Day wars. Formerly King Alteon's Royal Treasurer, until he was given the ability to turn anything he kissed into gold and promptly went over to the dark side.
Following the Chaos incident, Empress Gravelyn sends the Hero to meet with Bayconn, King Alteon's tax collector, in order to collect on her father Sepulchure's Unlife Insurance policy, which turns out to be for 1,000,000,000,000 gold.
Being far too greedy to just give him or her the gold and be done with it, Bayconn has the Hero thrown into Swordhaven Prison for treason. The Hero escapes, beats up the guards of the prison, and then destroys Bayconn's Piggy Drake in order to get this greedy little pig to pay up.
