Hex
From Wikitrix
Hex is a Master Magician. In "Lucky Girl", he possesses five magical charms called the Charms of Bezel that give him the powers of levitation, fire, reincarnation, lightning, and luck, in addition to his own spellcasting abilities. He attempts to steal an ancient spellbook known as the Archamada Book of Spells during the episode. It dates back to the 16th century and contains powerful spells that, when wielded by someone holding the Charms of Bezel, give the wielder unimaginable powers. He is eventually defeated by Gwen, Ben, and Max. Gwen also smashes the charms.
Hex returns in "Tough Luck", where he's searching for the Keystone of Bezel. With it, he can recreate the other five charms and multiply their power ten times. He is accompanied by his niece, Charmcaster, who is his apprentice that freed him from prison earlier in the episode. She eventually betrays him an attempt to get the power of the stones for herself. As Wildvine, Ben crushes the five charms and damages the Keystone, causing it to drain both Charmcaster's and Hex's powers.
Hex returns in "Don't Drink the Water", having aged into an old man since his last appearance (from the destroyed charms in his last appearance). Learning of the Fountain of Youth, he tracked it down and uses it to become young again, only to have the fountain vaporized by Heatblast. As a result, Hex is overexposed and is reverted into an infant, where he is later found, captured and taunted at by Charmcaster.
