Greed is a powerful demon from the Actraiser universe and a boss in Actraiser 2 who took over the city of Leon via possessing its king and transforming him into a large golden dragon that soon transformed the palace into a monument to greed, taxed the people and imprisoned any who could not pay.
The Master sensed the great injustice and sought to free the city from Greed, the dragon could attack with flame but was otherwise a rather easy to defeat opponent considering his status.
At any rate with Greed defeated Leon's citizens were free of the terrible tyrant and presumably began rebuilding their lives.
