FINAL SUBMISSION:
Pincrushen
Pronunciation: Pin-krushin
Origin: Pincushion + Crush. Pincushions are routinely stabbed with pins, like CAP11 has endured by the time it evolves, and "Crush" adds fighting flavour with a somewhat dark connotation.
------------------------------------------
Looking back, I like Voojitsu, it combines martial arts and black magic in a really obvious way and flows.
Stitchit and Fistuff are nice, referencing two features of CAP11 that haven't been touched upon yet by other authors, who are focusing more on pin, needle, and voodoo. I think stitchface makes CAP 11 seem more like a cursed outcast than stitchit does, almost as if it has an ominous, derogatory nickname others call it that stuck.
