Mystogan is an S-class mage known for putting basically everyone around him to sleep—it's his go-to move for avoiding attention, since he really hates being seen. Makarov's immune to it (though he still gets drowsy), and Laxus has apparently caught a glimpse of his actual face at some point. Beyond that, details about his abilities stay pretty vague.
He's got a distinctive look: a bandit-style mask covering the lower half of his face and a cap pulled down low, with just a slit showing his eyes. He also carries around a mysterious staff that's never really been explained.
⚠️ Note: Mystogan's true appearance is a major spoiler—please don't post any images that reveal his face.
