Disenchantix is a negative version of Enchantix and has the same power level.
The Trix were given this power by Valtor in the episode "Witches' Revelation" from the third season, and it was shown to be extremely difficult to defeat them. It is unknown if witches can obtain the Disenchantix by themselves, doing some requirement or if only another evil being can gives them this power.
The Disenchantix consists in outfits that are similar to swim suits with edges that can be of different colors, long transparent skirts covering the shorts and mantles attached to arms, long and dark boots. The makeup on the eyes grow more and becomes more clearer. The hair remains the same changing only for the addition of a tiara.
