Bio
Nitro is first seen when Ozone tosses to him Duke's collar. When The Flushed Pets is in the middle of the initiation of their new recruit, Max, Nitro screams stop and everyone looks at him. Nitro, with some other members of The Alley Cats, tells that Max and Duke aren't stray animals but pets, as they just robbed their collars earlier. Hearing this, Snowball orders the animals to catch the two dogs, but they can't get close to them because Duke bites Viper and swipes nearby animals, even Snowball is also thrown down to the water.

Later, in Leonard's Apartment, while Buddy and Mel feel puzzled that the dance party is not costume party, Nitro appears and rock with the music.
