I was waiting for someone to do a model of Roll for pony then, like Thanos said, "Fine, I'll do it myself".

For classic costume:

Roll (Mega man), android, long hair, blush, bangs, blonde hair, long sleeves, green eyes, hair ribbon, ponytail, sidelocks, boots, frills, red skirt, red dress, frilled dress, knee boots, red footwear, outline, green ribbon, undershirt, flat chest,

For original costume:

Roll (Mega man), long hair, bangs, blue eyes, blonde hair, dress, ribbon, hair ribbon, ponytail, sidelocks, red shoes, sleeveless, blunt bangs, flat chest, sleeveless dress, red dress, green ribbon,

Add retro for getting a closer look of original Roll,

It's not a perfect model but it's good enough to be useful. There are a few more costumes on dataset, so you can try to combine with random prompts.
