I try to create a Nemesis Model. It may not work perfectly. This will depend on the model you use (for example, PonyXL Autism DPO tends to be more human-like). But will probably work fine with model like Illustrious or Noobai

Prompt : NemesisRE3, Black boots, long black leather coat with buckles and straps, Strapped gauntlets, Stitched flesh,Exposed teeth, fleshy, tentacle around neck, zombie, bald, male, stitches, muscle

You can try to add : White eyes, muscular, monster, Full Body, Giant, one eyed

Or if you want one of his weapons

Bazooka :

- Holding Bazooka in right hand

- Holding Rocket Launcher in right hand

Minigun

- Holding Minigun in left hand

Tentacles attack :

- Tentacle on forearms

Flamethrower :

-Flamethrower on left hand

Also, If you use it with a "Jill Valentine loras". He can work well and understand that's a different character (but don't try to add Jill without any other loras)
