A tragic but simple backstory (explanation in the comments).

So back then many other people invaded the Black and White realm, there were 2 circle demon brothers, one being an unnamed demon (which I call “Big Brother”), and one being Albin.

They both don’t have any parents so the Big Brother kept the little one safe, one day when the invasion happened he got killed when a goat Pipnik threw a spear at him, terrified and heartbroken, Albin turned into a wolf and the Pipnik got mauled to death, and so, he hated every other species until he met Bloo and Elder after he accidentally got caught in a mouse trap, at first he wanted to kill them but he realized that they weren’t harming him in any way and decided to stay with them.

Yeah, sorta like that.

I guess it is.

Bugs: I’m sorry for your loss...
Thomas: my backstory was worse!

Coco: tell me about it!

Albin: .

Thomas: my backstory is obviously more tragic
Bugs: bruh seriously

Coco: then tell me then.

Albin: (Ō”)

Thomas: one of my stupid friends dared bugs to go into some dumb “haunted” restaurant, and I offered to go with him, because he gets scared easily. I watched a man in a dumb rabbit suit stab bugs to death right in front of me, before strangling me to death

Albin: that’s.. basically the same thing as that “Freddy’s Pizza” incident.

Thomas: it was legit at freddy’s Pizza. Years after it has been shut down. He stabbed my brother in front of me. I bent down to save bugs and he strangled me from behind
*a tear runs down his cheek but he quickly brushes it away*

Ezlo: that story would have been better if this never happened

Thomas: no you
Bugs: god you are such an idiot sometimes thomas

Ezlo: can both of you shut up

Thomas: no-
*bugs covers his mouth*
Bugs: yes

Ezlo: I like pain

Thomas: find someone else then. I don’t happen to have a death wisg

Ezlo: punch me Thomas

Thomas: I’m not that dumb
Bugs: debatable

Ezlo: please?

Thomas: why the heck would you want to be punched?
Bugs: it’s a trap you idiot

Albin: ...

Bloo: that’s disturbing.

Thomas: there was nothing I could do...
*he slumps against a wall with his head in his hands*
Bugs: well I’m still here...
Thomas: I saw the knife go through your heart! I heard you scream! I saw your crumpled body. It does stuff to a guy

Sparky: correction: you made our lives hell.

Thomas: I’m borrrrrrrrred what can I doooooooo?

Bloo: mmmkay.

Bloo: says the Tank Engine.

Thomas: says the fat ass cat that doesn’t even have fur

Bugs: and you got him fired up again

Albin: tbh idek.

Thomas: I’m also kinda hungry but too lazy to get food
Bugs: I am not getting you food

Bloo: *whisper* I think this is one of the rare times I see Thomas out of character.

*they both start laughing*

Bloo: okay okay jeez.

Thomas: I’m surrounded by idiots
Bugs: deep breaths
*thomas takes a few deep breaths and returns to normal, and then he looks at red stick cat*
Thomas: did I do that?

Bloo: ow.

RedStickCat: yes?

StickCat: how are you not screaming in pain-

Thomas: oh well I’m not sorry
