Hydrogen Peroxide, known as Dihydrogen, was a child of Benzoyl and Acetone. The relationships were not healthy, as Acetone often left to go drink and Benzoyl was always forced to stay behind. Dihydrogen was born a female, but soon discovered that he feels comfortable as a male, and after a year or so, finally came out to his parents.

Benzoyl didn’t hate Dihydrogen, in fact, she was ecstatic that her own child would trust her. Father, on the other hand, hated that. Acetone slapped Dihydrogen and left as he and Benzoyl were stunned. Acetone never came back for Dihydrogen, and eventually, he stuck to the name Hydrogen, while Benzoyl called him Peroxaan.

Hydro developed bad coping mechanisms, one of which was arson. He burnt himself many times due to his recklessness and dares. Benzoyl always cried over him, always so worried for her child, but Hydro pushed her away and when it was time, left her so that he wouldn’t hurt her anymore.

Meeting Ghoxi reminded Hydro of Benzoyl, so when he lost her, he couldn’t bear to deal with the pain. It caused relapse in him that he tried to repress all those years.

And now he's here, suffering and in pain from the consequences of his actions. Thankfully, he has shoulders to lean on... For now.
