Arthur(NA)/King Arthur(EU), who was raised by the great sorcerer Merlin, became the Master of the Excalibur and then built his kingdom. King Arthur uses Return of the King, teleporting to an ally base; King's Blessing, giving an Armor Destruction Buff to allies; King's Power, where he/she explodes with power and stuns enemies; and Song of the Sword, summoning an earthquake that can be helpful for team play. If you have King Arthur on your team, it will be far easier to win.
* Also available in a female version.
- Arthur has also previously been named Arthur Pendragon.
