Here's an Illustrious model of Groudon from pokémon. It's a model that's been very hard to train.

I warn you in advance that it's probably only the classic Groudon (in terms of color and shape) that really works properly. The other versions should work, but you'll have to use inpainting to make it perfect or redo the generation. Anyway, here's the list of all available tags.

Trigger word :

Groudon, Red skin, black line on the body, Gray belly, gray jaw, yellow eyes, black sclera, white claw, white spike on the side of the body, white spike on the side of the tail, large tail

For the "classic" Groudon use : Feral

For the Primal form : Primal form, Lava line on the body, Red eyes, Lava sclera

For Humanoid/Anthro version : Anthro

For Girl (humanoid) version : Rule63 (You can also use Futa for futa version)

For Normal Shiny Form : Shiny, yellow skin

For Primal Shiny form : Shiny, Primal form, Lava line on the body, Black skin, Red eyes

If you don't know what to remove for correct use. Just look at the tags of the pic from the model.
