Doomguy’s (great?) aunt and BJ's great granddaughter from Microsoft’s 2019 out of season April Fools joke. Since I’ve done characters from 30+ year old edutainment material, I will now cement my status as master of the obscure by making a LoRA for something that never even came out! I’m glad this was canceled, but the designs and trailer (for some reason) looked like they were actually well made by people who cared so it’s a shame MS didn’t make a singleplayer/co-op platformer with these two after canning the mobile abomination.

Billie: ki_gi, red hair, american football helmet, short twintails, hair through headwear, dress, red dress, belt, belt buckle, lighting bolt symbol, white pantyhose, white boots, thigh boots, (you can try removing the boot tags if they prove unstable)
Checkpoint Dependent: missing tooth (some just will not understand this)
Negative: fewer digits (The two have hands with 3 fingers+thumb, and four toe feet)

I actually initially made a version with both her and her brother, but it was too hit and miss with making her accurately. I included it as an extra (the "co-op" version) since that produces her brother just fine and you might be able to wrangle something better than I could.

Both: k33ns
Billy: ki_bo, red hair, freckles, american football helmet, short hair, red shirt, print shirt, lightning bolt symbol, shorts, white socks, shoes, bandaid on knee (don't expect symmetry)
Billie: Same but was trained on just "pantyhose, boots" instead of the more detailed tags.

The combined version was made with 39 screenshots of the trailer: 16 with both, 11 of Billy alone and 12 of Billie alone. The Billie only version was made by taking those 12 pics, adding another 12 cropped from the shots with both, as well as a piece of fan art. Incidentally, I think their true names would be William Blazkowicz III and Billie Blazkowicz, but the trailer does explicitly identify them as "Billy Blaze" and "Billie Blaze" (continuing their grandfather's stage name) so I'm going with that for the title.
