So I know there's already a decent Pony Checkpoint based Character LoRA on this character already that works quite well with Illustrious all things considered but I wanted to train up a dedicated Illustrious version of her just to see how well it would come out and I think I did not too bad at an IL version of her.

So anyways this is the Blink and You Will Miss her character from Helluva Boss who you see in the season 2 episode "Oops" for about a minute that never got a name at all and people ended up calling her Succubus Work Assistant for the longest time before the fandom shortly after just named her Sparkles J even though I call her personally Vivienne because she's voiced by the actual creator of Helluva Boss Vivienne Medrano for the moment she's on screen.

So I trained this version of Vivienne Sparkles J quite a bit on fanart from DeviantART and even a bit from the episode she's in using PotPlayer and finding decent enough keyframes and going into Photoshop to edit the boxes she holds out (thank god Vivziepop's art style is basically Vector Art makes cutting stuff out A LOT easer) since that was a problem with the Pony model of Sparkles that the boxes she would be holding would render in quite a bit somewhere. Also went on Rule 34 and found some more fanart and even some decent elements of AI Art (a first for me) of Sparkles to use as face/head shots data references and also went on Nano Banana Pro as always to bulk out the training data and had to use Topaz Gigapixel a little to uprez the images it spat out a little since they were quite small.

Anyways to summon this version of Sparkles J you use this prompt command.

1girl, solo, sparkles_j, white_hair, short_hair, pink_skin, horns, freckles, glasses, round_eyewear, yellow_eyes, tail,

And for her outfit.

dress, skirt, high_heels,

Her outfit maybe slightly baked in quite a bit so you may want to add "dress, skirt," to the negatives if you want to dress her up in certain outfits like a Pant Suit for example but it's really not bad enough that I wasted 1.25 USD in Blue Buzz to throw it all out and also if you notice a bunch of stars around her head for no reason at all that's because Stable Diffusion notices her summon word is also a prompt it knows so add also "sparkles" in negatives to stop that from happening.

Also add "black pupils" to your positives to enforce her eye pupils so they consistently render in better if you notice Sparkles eyes not rendering in any pupils that did happen at times when I was testing the model in JANKU and a bit in Hyphoria earlier on before that it would just render yellow eyes with no pupils that makes her look kinda creepy.

Overall I think I did no too bad for something I wanted to do since after all this time there was no IL version of this one shot somewhat obscure character that even a year plus later STILL does not have much images that could be used as proper guidance data to work with.

Anyways enjoy!
