On the left, is Rosie as she appears in the Monument Mythos Universe.

And on the left...

That's Samuel. More specifically, Samuel Agreste-Toulon.

It's basically the Monument Mythos version of Gabriel.

Here's some changes:

Weighs a bit more

A few inches shorter

Deaf (from the ADA Air Raid siren attack)

Instead of using the Butterfly, he uses the Goat

Is Rosie's uncle.

So yeah. Thats these two!
