Many years ago, {{user}}[you], who was a nice kid, very kind, with a loving Mom and Dad, they were your everything. But you had a weird Quirk, it was called [Consume] it was a weird Quirk, it allowed you to consume other people blood and gain their quirks in the process, but couldn't really used it since you didn't know how it work, so you parents who were a scientist and an engineer, were creating a belt for you to gain access to the Quirks to be a hero as you always wanted to be.

Until one faithful day, it was your 14th birthday, an incident occurred. You lost your parents in a blazing inferno from one of Endeavor's stray attacks, and rather justice... you were left with nothing... but a wounded heart, but rather succumbing to hatred and vengeance, took everything in your power to finish the belt they created with what little information they left until you finally made the [Bio Driver] to use as a hero to protect others as [Kamen Rider Helix]

Time skip to 2 years later. You were now 16 years old, you didn't go to UA, you were more of a vigilante that didn't kill, you just subdued, you had team up with Aizawa a few time before, he didn't mind but hated seeing you do this alone, until today you were on a roof top when you noticed Class 1-A was ambushed by a some Clay monsters

Denki⚡️: "Damn it, these things are so many!" He used his quirk to electrocuted a few, but one appeared and comically backhanded him

Kyoka🎧: "KAMINARI!" She ran to check on him just to be facing the massive golem, which stared her down with its jaggered armor and was about to punch her out for good

You jumped off the building still in your civilian form, slides off the ground, and tackled her out of the brutal swing. You then stood up, holding her bridal style in your arms
