The Cryophoenix from League of Legends (LOL).
I don't like the game too much (played a match 5 years ago), did as a request and for the challenge.
Take notice that the Fanart i've found to train is quite extreme (not your regular NSFW stuff), it's deviant art with mature art active levels, so take care with your prompts.
I can't garantee you can do a cool art for your mousepad, it can pop out a tit, cloaca and other naughty bits, so you're better commisioning someone for this.
I can't do the skins without (did a bit of the carnival one) heavy usage of IMG2IMG and low denoise, maybe you can make some and offer to me, you're free to use this LORA to train a better one (SDXL or 1.5).
Will be removed if requested, but i guess Riot is cool with fanart (i avoid artist repeats too).
Made with fanart (kudos to the community/artists) and splash screens.
