Motormouth. Has a somewhat daunting and critical facade, and an "inimitable way... of being both acidic and affectionate".
Suitov's stated OOCly that Nico "was the oldest of us [the bachelor pack]--chronologically and in relative biological terms, not to mention psychologically--and he made a very effective brood-parent to the rest of us. Lottir knew him the longest. Nico did not suffer fools gladly or at all (except for me). He was a perfectionist, most particular about accents and very patient with a select few." (N.B. Either he was mistaken about age here or his writer got it wrong; Lottir is technically older, but Nico acts it.)
He doesn't drink alcohol very often.
Named after a puppy from Crete.
