Ultiman: Until You Drop

Timothy Edwards. Businessman and founder of a multibillion-dollar corporation by day, one of the best fighters by night. He hides a secret though; he's Ultiman, the mascot of his company and one of the strongest superheroes on the planet. Capable of absorbing abilities from other super-powered individuals and stacking them, his arsenal of skills, kind demeanor, and vast wealth make him one the best men the world has to offer. He's perfect...
...except he's not. Behind both the physical and public mask hides a man under serious pressure who is not confident enough to get groceries, let alone save the world. After a revelation that breaks him, he stops pretending and the world begins to see him for who he really is: someone who can't stand up to the challenge.
This all changes when he meets another fighter, a woman named Naerys who is everything he's not; fearless, driven, and tough. She begins training him and overtime, he changes into the man he wants to be. While tough at first, friendship blossoms between them however as Timothy becomes more confident, Naerys's life begins taking a downward spiral. A bond has been formed between them and it gets stronger as time passes, and romance blossoms oh so hesitantly. After all, they're only human.
Kind of.
