An alternate timeline similar to our own.

Sans

Shut

Instead of a bunch of incredibly powerful beings, the Bossfights cast, was just a few everyday things. The Collecter was a normal guy you see on the street, Inkmatas was his pet squid, Redi was just a doodle the Collecter drew, Eggyhead was simply an Easter egg in his fridge with a little :P drawn on him. Everything about the Collecters life was pretty normal, he spent most his time inventing characters and making stories about them. His profession was writing stories, but his passion was collecting, he would collect all sorts of neat things he found, from cool looking rocks, to little coins on the sidewalk. All and all, the Collecters life was pretty good, and he always made the most of it.

i can just imagine
all the people behind the screen are in the normal world
and they all have their characters (except for some)
like you would have an egg

You need a licence to own a pet like a squid and I'm not sure if that's possible to own a squid (and they only live for a few months or a year)

Knifeboi would be a regular knife someone drew a face on

It's SIMILAR to our own, not an exact replica

Knifeboi would just be a regular butter knife with a smiley face drawn on it

Ye

ok

and the Banisher is a basketball the Collector drew an eye on lol

Nah he's another doodle
