Oni under The Crimson (Patreon)

"A mysterious remnant of dictator Razmir's super soldier program. Fort exhibits a level of strength unmatched even for those with dedicated muscle-enhancing cybernetics and the bulkiest of the Snow Treaders, coupled with the uncanny ability to seemingly adapt and/or desire to overcome any threats when she put her mind to it, yet the surviving off-site document only mentioned her as a defective product. Thankfully Razmir's program failed catastrophically along with the facility itself, I do not think even our best creations stand a chance against an army even better than Fort herself." - ???
