Sweet Mask

Handsomely Masked Sweet Mask (イケメン仮面アマイマスク, Ikemen Kamen Amai Mask) is the A-Class rank 1 superhero.

Appearance
Sweet Mask is a good looking individual with keen eyes and lightly colored hair, an appearance befitting that of a star. After the battle against Sea King, he is seen with longer hair when he addresses the Heroes Association official. In his most recent appearance, Sweet Mask is shown with short hair again.

Personality
Sweet Mask has stated that he believes that heroes are to protect the citizens, and if they can not do that then they must become stronger. He appears to be quite popular and has quite a charismatic way of talking.

However, befitting the darker side of Sweet Mask's name is his hidden merciless nature.

This is shown when he readily and swiftly dispatched a group of captured aliens whom he declared to be evil, stating that he merely executed justice on the spot. This was shown again when he was ordered to bring an escaped caveman back to the lab, he ignore the superior's order and kill the caveman instead. Sweet Mask is shown to adhere to any method that makes heroes popular, noting that only promotions to S-Class or A-Class are fit for his attention, asthey are the heroes who draw the most attention from the public, and hence, any heroes in those ranks who earn themselves negative reputations would drag his reputation down as well.

The other heroes watch shocked while Genos thought about how, before meeting Saitama, his way of thinking was similar to Sweet Mask. Because of his mocking attitudes towards the S-Class Heroes, and his theories on keeping the low level heroes below A-Class, he was challanged by Metal Bat for a fight, until they were interrupted by a phone call from Sweet Mask's manager and Metal Bat's sister.

Abilities
Not much is known of Sweet Mask's abilities, but he claims that his skills are strong enough to put him in S-Class. He chooses not to advance so as to not allow weaklings to rank up.

He appears quite fast as he was able to murder a group of captured alien invaders, apparently slicing them through with his bare hands, in a matter of seconds; with none of the nearby S-Class heroes being fast enough to stop him.

It is revealed that he possesses brute strength and his veins are shown whenever he's extremely angry. He quickly and effortlessly defeats Suppon, kicking out his legs and smashing his face in with a pressure burst.
