Mystel is an enigmatic character, as noted from Beyblade episode 34: "My Name Is...". He exhibits quirky behavior and prefers to stay in elevated spots, often observing his teammates. His unique abilities give the impression that he can hover in mid-air. Water is his element, which he wields effectively.
Generally, Mystel is a pleasant individual, though occasionally direct with his words. This demeanor somewhat offends the White Tiger X team when they encounter him in their camp; he remarks on how they clearly cannot retrieve fruit from atop a cliff like he can. Despite this, he appears to befriend Ray and the White Tigers upon his introduction. Mystel nearly convinces Ray to join BEGA. He embodies a free spirit and maintains a joyful disposition. It's believed he is the youngest member of his team.
Mystel's Beyblade attacks are highly unpredictable. Opponents describe his technique as a 360-degree assault, utilizing a bit-beast named Poseidon. Despite his small stature, Mystel proves to be a formidable blader, effortlessly defeating Lee from the White Tiger X team and holding his own against Ray until an accident interrupts their match without determining a winner.
Mystel's Beyblade, Poseidon, features the Ocean Javelin attack.
