The Evil Wizard is responsible for stealing the magic crystal, the kidnappings of the four princesses, as well as all the monsters and fire demons that plague the land. He is also responsible for all the "beefy" enimies roaming the kingdom. His goal is to take complete control of the world and turn into his own personal domain filled with death and despair. To exert his power and influence, he seems to have been scouring the lands for crystals that contain immense power so that he may use their power to not only conquer the world, but use their power to shapeshift into various forms. To accomplish his plans, he has set up many of the crystals to power his fortress in order to give it enough power to launch into space and reflect their power into every corner of the Earth and place it under the Evil Wizard's control.
Aside from his obvious lust for power, the Evil Wizard is also extremely sadistic and violent, causing death and destruction wherever he goes and is personally responsible for the deaths of millions, perhaps even billions of people. His fortress is located in a barren wasteland filled with skeletons and his throne room contains a fallen crown, hinting that he completely and utterly annihilated any towns, villages, and cities that resided there, murdered the king and usurped his power and fortress for his own purposes. From there on, his fortress became a place of such vile horror and violence that certain rooms began overflowing with blood, skeletons and one particular room even contained thousands of mutilated corpses from various races that have been tortured to death (perhaps for having failed to destroy the heroes).
As the Evil Wizard built up his power, his army extended into millions of warriors ranging from Barbarians and cut-throat Thieves to his own personal followers, including the Necromancer (his right-hand man), to do his bidding. In order to help in his quest for world domination, the Evil Wizard forms relationships with dark kings from other lands, bribing them to help him conquer the world by promising them a princess. It is for this reason that the Evil Wizard abducts the princesses to give to the other rulers in exchange for their kingdom's allegiance to him, while also intending to keep one by his side when he conquers the world. Through this, the Evil Wizard gains machinery from the Industrialist to help him reinforce his army and gains demonic warriors from the Cyclops King and the Frost King. With these three kings under his rule, the Evil Wizard massacres the land, even using the Necromancer to reanimate many that he killed to join his army.
With his humongous army, the Evil Wizard leads a full scale attack on the Castle Crasher's kingdom, creating a war of unspeakable violence and death. He succeeds in stealing the crystal and abducting the princesses, leaving the land barren and millions dead. The other kings succeed in conquering other lands and place them under their control, later inheriting the princesses as planned. The Evil Wizard would personally survey many lands to attack and conquer and rally more for his plans.
He would cross paths with the Castle Crashers several times and would place many obstacles and monsters in their path. Eventually, the Castle Crashers wiped out most of his army, rescued three of the princesses and destroyed all three kings. However, the Evil Wizard would resurrect the Cyclops King and The Groom, who served the Cyclops King, as a pair of zombies and betray the Industrialist by taking his princess and leaving him to die at the hands of the Castle Crashers. The Castle Crashers would eventually make their way to his fortress and destroy the remains of his army, finally leaving the Evil Wizard no choice but to engage in an ultimate showdown with his hated enemies for ownership of the crystal, the final princess and the world.
- He is one of the few characters to have no quotes.
- He is seen mostly wielding a Practice Foil, which gives very little Magic bonus. While this may be confusing, it only serves to show his immense amount of power.
- He is able to draw out the fire element from the Demon Sword in his final form.
- This boss is 6 bosses in one.
- When he walks, he does not bend his legs and it appears he does not have any knees; this suggests that the Evil Wizard may not even be a human.
