Dragon

Ryuko Tatsuma holds Dragon, a close-range Transformation Quirk that debuts in chapter 138 and reaches the anime in episode 70. The Japanese name is simply Doragon.

The Quirk does exactly what the name promises, converting its user into a dragon, and hands over the traits the legend implies. Flight arrives with the body, as do a formidable set of jaws and claws.

Raw power scales sharply in the transformed state. Ryuko stops a punch from Rikiya Katsukame without visible strain and holds the enhanced-strength yakuza in place. Later, even after Energy Suck has drained her, she still lands a blow that hurts him and drives him back, and this against an opponent who had just walked through one of Nejire Hado's Wave Motion shockwaves.

Toughness rises alongside it. The strongest attack her trainees can muster lands on the dragon form and leaves nothing behind.

Crucially, the new anatomy costs her no technique. Ryuko keeps wrestling with the same instincts she uses as a human, catching an opponent's hands in her claws, locking in submissions, and pressing her fangs into service as an extra limb to secure a hold.

Ryuko Tatsuma is the only recorded holder of Dragon, and the Quirk is filed among the Pro Hero powers.

Its clearest showcases both come against Rikiya Katsukame, where the transformation's strength, durability, and grappling all surface in the same engagement. Her trainees appear in the record as well, both as the sparring partners whose full-power strike the dragon form shrugs off and as allies during that yakuza fight.
