[Scripting Question] Overlay Image Onto Pokemon Sprites

[CoolsMcFrosty]

Hi! So I'm trying to make a system that adds a bit of random color variety to the pokemon, for a bit of realism. Is there any way for me to make a script that allows me to pull an image (colored eyes, for example) and lay it directly on top of the existing sprites? WhenI tried to do it before it just replaced the image entirely and I had a pair of floating eyeballs instead of purple eyes on a bulbasaur like I wanted.

I've already made a file checker that works similarly to the shiny checker; I just need some code to get it to overlay the image it grabs rather than replacing the sprite. Thanks!

Could you not just use forms instead of overlaying a sprite or series of sprites over a Pokemon?

I would, but I want the traits to be breedable so they need to be on their own separate variable. If not I'd have to manually make every single possible combination of eye color, body color, marking colors, etc.
