Alexander

Alexander is an Overlord from Makai Kingdom. Also known as the "God of Destruction", Alexander is Zetta's rival and has attempted to kill Zetta many times. Zetta has actually kept track: Alexander has sent 20846 assassins and has started 6413 wars with Zetta and still hasn't won. Zetta also refers to him as Alex, Alejandro and Asshat. He is extremely arrogant and egotistical, like most Overlords are, and is always ready to fight Zetta. Alexander is also the master of Raiden. Him and Zetta share a "friendly rival" relationship in the way that, despite countless death threats, Alexander saves his life two times at the story's end with no input from Zetta.
