At school, he quickly develops a crush on a popular girl Jenna and makes an enemy out of her ex-boyfriend Troy Adams.

In biology class, Duncan befriends fellow outcasts Kenny and Isabel, the latter who happens to be a Kaiju-obsessed fangirl and develops a crush on him.

Late that evening, Troy's friends break into Jenna's locker and steal the money she was holding for the school's Homecoming.

Waking in the desert, Duncan encounters Kenny, who tells him that Isabel told him about Belloc being his father and asks why he was at the party.

However, after Troy and Jenna are elected Homecoming King and Queen and go on stage, Isabel romantically dances with Duncan, enraging Kenny.

Mania.com's Rob Worley viewed Firebreather at the New York Comic Con, awarding the film a B+ and stating "Teen Angst + Kaiju Big Battle = CG Awesome!," but criticizing how the animation could be "... somewhat distracting as the characters sometimes have a puppet-like appearance."

[4] David Hinckley of the New York Daily News stated that "in general, it succeeds", calling its romance elements "chaste" and "just to make things interesting for someone other than 10-year-old boys".

Bonus features include a 2D animation test, deleted scenes, animatics, and a visual development featurette.
