So at the end of one of the trailers for Splatoon 2, I saw some concept art. At the top, there was a shadow with goggles. When you take them off, it seems really obvious who the villain really is because not only does it look like CALLIE but it is reddish-purple which is the Octarians' ink color. In conclusion, I declare that Callie is the PRIME SUSPECT of the crime. (Okay, maybe that was a bit dark) But still, She is actually (Possibly) the Octarians' new leader after DJ Octavio wash defeated in 2015 (When the original was out.)
