That rules out majority of the bosses here, but let's see who is the most original of the few that are.

One of my ocs autumn who is a normal human

databoot is more of a self insert

My most original ones are

Collector, data, creatie, and tsar

Astra and terra aren't as original because Astra has similarities to XJ9 and terra has similarities to earth chan

In fact both of those were inspiration for them

Probably Rizu

I have ptsd from this image

But for me it’s Saike

Wait why ptsd?

Snowgrave route

The end

Oh

OH SHI-

Oh you beat it, congrats

I DIDNT YET

oh.

Bunii and Anii's og forms are actually original.

Shad

I would think my oc, Ren, is
(Mainly the most original out of my ocs)

Isn't he a shovel knight reference?

Nope

How original do you think Gingerbread Man is? IMO I think a Gingerbread cyborg was pretty clever

I think Montie might be even more original though

IDK, I'm not an OG
