Sera, from the Mega Man Legends series, is the main antagonist of Mega Man Legends 2. Notably, she is the franchise's first female final boss and holds the unique position of being the final antagonist in the original timeline, sharing this role with the Crimson Dragon from the alternate timeline.
Her character draws heavy inspiration from Princess Kaguya in the Japanese tale The Tale of the Bamboo Cutter, particularly in her lunar connection (Elysium) and her armor, which features a rabbit motif.
Personally, I have a strong preference for female characters with long hair. Out of the many I like, only about three have short hair—coincidentally, all Capcom characters—making Sera as rare to me as a Shiny Pokémon. But it's natural that, being the only Mega Man character to appear nude on-screen, she would have a psychological impact on a 7- or 8-year-old boy for the rest of his life.
The model is decent considering there is so little official source to be used.

This version includes all of her appearances (excluding her on Yuna’s body, for obvious reasons 😂).
Since the second and third forms only exist in-game and lack official artwork, they naturally adopt the visual style in-game of Mega Man Legends. If you prefer a different style, you may need to lower the strength slightly and pair it with another LoRA.
Her normal form is nearly flawless, but the symbol on her dress can sometimes remain if you attempt to change her outfit. This issue can be resolved by removing the tag “tattoo” from the prompt, as it seems that tag absorbed the symbol from her clothing rather than the shoulder tattoos for some reason.

The trigger word is MSera and you can use short hair, green hair, red eyes, dark skin, white tattoo on shoulders to help.
Use white dress, mml2 dress, turtleneck, white boots, long boots, purple wrist brace for the complete outfit.
