Nitrus Brio

Nitrus Brio (N. Brio for short) is a scientist who formerly worked under Doctor Neo Cortex. Brio's loyalty has fluctuated throughout the series, working on his own accord in Crash Bandicoot 2: Cortex Strikes Back, with Doctor Nefarious Tropy in Crash Twinsanity, and even returning to Cortex's side in Crash: Mind Over Mutant. His name is a play on the word "embryo" (a fact that he himself alludes to in Crash: Mind Over Mutant).
