the closest ocxcannon i got in splatoon is the idea of adding callie to the cule
i have a ocxcannon ship outside of splatoon that i need to flesh out more but it's Memato (oc) x DeDeDe x Meta Knight
i have a couple ocxoc there's the polycule of Ski, Kabi, and Ziphi
Umbra and Dyanie are QPP (they also have a salmon kid cuz reasons)
