Mystel

Mystel is inherently a rather enigmatic figure, as noted in Beyblade episode 34, "My Name Is...", and he comes across as quite eccentric. He passes his time perched in elevated spots, hovering near his teammates whenever they need to gather. He possesses odd abilities that give the impression he can hover in mid-air. Water is his element, and he wields it effectively.
Mystel is generally a good-natured fellow, though he can be blunt in his speech and appears to slightly irritate the White Tiger X team when they encounter him in their camp; he remarks on how they clearly cannot retrieve the fruit from the top of the cliff as he can. He seems to have become friends with Ray and the White Tigers upon his initial appearance. He almost convinced Ray to join BEGA. Mystel appears to possess a very free spirit and is a very cheerful person. He is thought to be the youngest member of the team.
His Beyblade attacks are unpredictable. Bladers claim that he employs a 360-degree attack, and he utilizes a bit-beast named Poseidon. Despite his small stature, he has demonstrated himself to be a formidable blader when he easily defeats Lee of the White Tiger X team, and he holds his own against Ray before an accident occurs, forcing the battle to end without a winner.
His Beyblade is Poseidon, featuring the Ocean Javelin attack.
