Suggested by iKnowledge Gwen has obtained some pretty powerful abilities during the Ben 10 series. At her best her magical powers could actually pose a serious threat to the Enchantress. That being said, Enchantress did become a herald of Surtur at one point so defeating her certainly won’t be easy. I think Enchantress certainly has more experience in combat which will work to her advantage and at the end of the day I would also say that her spells are superior. Enchantress wins.
