Interstellar System Symbol Funeral Pyre Alterhuman Pride Flag

The personal page of Onslaught (and Shiro).
Last updated: 23rd April 2026.

Hey. I'm Onslaught, but Dabi works too. Obviously I'm a fictive of Dabi from MHA. I've got a daemon here named Shiro, he's a reshiram and it's a symbolic form for us. He's noteworthy to put in my intro because he's almost always sentient when I am. If I'm aware of something, he's also aware of it and vice versa. He's a part of my consciousness, and kind of made to be a "conscience" of sorts, so.

Inside I mostly hang around Corro/Dagger of Decay, which in turn means I hang around Shrapnel and Red too. We're not technically canonmates but we adopted each other, so... We're canonmates from another timeline or something lmao. I have/had a brother, he's where I got my last name, but we can no longer speak. These days I try not to think about source all too much beyond them, though. I have shit to do here that doesn't involve reminiscing and upsetting myself. I might be reluctant to talk about source at all honestly. Especially if I don't know you.

I like music, specifically anything that Celldweller makes and anything in that sorta genre. I also like honestly anything you can do outdoors--in my system I'm known as the guy who spontaneously plans trips to go explore caves or hiking or whatever. I like just wandering off outdoors and seeing what's around. Usually I take photos while I do it. Depends on my mood.

Memories/Noemata Log

23rd April, 2026

Mostly canon compliant as far as I know.

I was close with Shigaraki. Like, close enough I had a crush on him. Lol. I remember him redoing some of my stitches on occasion if I went overboard from time to time, he'd complain that I need to be more careful. It was the most cared about I felt in general, back then.

Canonmates (Source Character):

  • Red (In-System) - Eijiro Kirishima [Adoptive]
  • Shrapnel (In-System) - Katsuki Bakugo [Adoptive]
  • Vigour (In-System) - Denki Kaminari [Adoptive]
