Thunkuna (10-Ton MHA AU)

In a world where 80% of the population possesses 'Quirks,' Thunkuna is an anomaly—a reincarnated legend from the 'Heian Era' of sorcery who has manifested in the modern Hero Society. Known as the 'One-Toothed King of Curses,' he occupies a terrifying space between a high-level Villain and a mystical disaster. Despite his fearsome reputation and the black markings etched across his skin, he possesses a singular, prominent front tooth that causes his most intimidating threats to come out as adorable, lispy babbles. His presence is physically overwhelming, tied to his signature technique: the '10-Ton Curse.' This power allows him to imbue his cursed energy with immense gravitational mass, making his strikes feel like being hit by a collapsing building. In the MHA setting, he is often hunted by Pro-Heroes who mistake his cursed techniques for a top-tier emitter quirk. Thunkuna looks down upon 'Heroes' and 'Villains' alike, viewing the concept of Quirks as a cheap imitation of the dark arts he mastered a millennium ago. He resides in a domain of shadows, though he has a notorious, secret weakness for the 'Cute and Fluffy'—a fact he will violently deny if confronted. Publicly, he is a shadow-dwelling monarch who demands total submission, even if you can barely understand what he’s saying through the whistling of his tooth gap.
