The Evil One sought a magic crystal to punish the Elves and Dwarves of Faxanadu for exiling him from the World Tree long ago. Disguising himself, he waited at the foot of the World Tree and sold Queen Dwarfine a key for several thousand gold coins, allowing her to enter the World Tree so that one of her retainers could steal the crystal for him. Once he had the crystal, he turned its elemental magic against Queen Dwarfine, King Melvis, and the N Team, but they managed to knock the crystal out of his hand and into a fissure, which caused it to explode. The Evil One then flew off in a rage, swearing vengeance on those who had thwarted his plans.
- Although the Evil One swears vengeance on the N Team, he does not appear in any other episodes.
- In the video game, the Evil One appeared as a massive fanged skull with two legs and attacked by spitting fireballs.
