OC Help: Name and Backstory, But No Design

I'm trying to make up a Yu-Gi-Oh OC, but I'm having trouble with his design. His name is the Mask of Fear, real name unknown(and not thought of), and here is his backstory

The Mask of Fear is a duelist who has never been defeated. He earned his title because of the mask he wears and the fact that he exudes a sort of aura that induces fear into people. His real name is unknown, and he has never been seen without his mask on. In reality, he is from an alternate universe, and he is the counterpart to Jaden Yuki. Like his counterpart, he has a passion for dueling, but his passion is much darker than Jaden's, he takes pleasure in dueling because it's his preferred method of striking fear into people. Also like Jaden, his Duel Spirit is the fearsome Yubel, and he uses a Yubel deck in duels where he isn't holding back. In his universe, Duel Academy is a military school that teaches students to use Duel Monsters as weapons. Similar to the Duel Academy of Jaden's universe, there are three ranks, Raviel Blue, Hamon Yellow, and Uria Red. Like Jaden, The Mask chose to remain in Uria Red, because he enjoys toying with opponents by making them think that he is one of the rookie students and becoming terrified of his strength and skill as a duelist. His Duel Disk is built into his armor, which he is also never seen without.

Now that you know he's an alternate universe's counterpart to Jaden Yuki, I only ask that you don't suggest making him look like a clone of Jaden, he already has similarities to Jaden, I don't need more.
