I'm not sure if he is officially stated to be Dragon, but in chapter 130 when Sludge Jellyfish is educating the child prisoners on the High Dragons, we are shown a splash page showing the Dragon level threats of the MA, and Nyan is shown amongst them in a panel smaller than the others, like his inclusion was hastily added later.

It is possible that Murata asked One if he could be made into a Dragon level threat and was added after given the go-ahead.
