On the last day of the war between humans and Kaiju, a human woman named Margaret Rosenblatt (voiced by Dana Delany) and a male dragon Kaiju named Belloc (voiced by Kevin Michael Richardson) fall in love, and have a son named Duncan. Sixteen years later, Margaret and Duncan (voiced by Jesse Head) are moving into a new house as he gets ready for his first day at a new school. However, Duncan fears that his orange skin and appetite for coal will make others think of him as a freak and a prime target for bullies. At school, he quickly develops a crush on its popular girl Jenna (voiced by Amy Davidson) and makes an enemy out of her ex-boyfriend Troy Adams (voiced by Josh Keaton). In biology class, Duncan makes friends with fellow outcasts Kenny and Isabel (voiced by Dante Basco and Tia Texada) who happens to be a Kaiju-obsessed fangirl who develops a crush on Duncan after he shows her a Gomorradon, a small frog-like Kaiju he caught in the process of apparently making a fool of himself. Late that evening, Troy's friends break into Jenna's locker and steal the money she saved for the school's Homecoming. The next day, Duncan meets up with "Blitz" Barnes (voiced by Reed Diamond), undercover as the gym teacher, and defends Kenny from Troy and his friends in a game of dodge ball. After a confrontation with Troy, Blitz takes Duncan to Dr. Pytel (voiced by Nicole Sullivan) at the M.E.G.T.A.F. base upon the discovery of him being able to breathe fire. Later back at school, Blitz smooths things over with Principal Dave (voiced by Gary Anthony Williams) to keep Duncan out of trouble. While he and Troy are cleaning up their mess in the cafeteria, Isabel tells Duncan about a party that everybody will be going to, and he agrees to go in hopes of romantically seducing Jenna.
A group of animal activists, consisting of Dr. Nikki Riley (Debbie Gibson), Gia (Arden Cho) and Ben (Patrick Hancock), break into a house and steal dozens of exotic pythons before setting them free into the Florida Everglades. Their actions inadvertently cause the snakes to grow into alarming sizes and threaten the ecosystem, as they kill over 72 alligators in a matter of days. Due to the threat of the invasive species, Park Ranger Terry O’Hara (Tiffany) issues permits to the local hunters to exterminate the pythons – much to Nikki’s dismay. However, the hunters themselves – including Terry’s fiancé Justin (Carey Van Dyke) – are quickly eliminated by the giant snakes. Vowing to avenge her fiancé’s death, Terry and Angie (Kathryn Joosten) take boxes of anabolic steroids from Angie’s grandson Manny (Chris Neville) and inject them into dead chickens before feeding them to alligators. Among the steroids is an experimental serum that neutralizes muscle growth inhibitors with a side effect of increased aggression. Meanwhile, Nikki and her group set up cameras all over the Everglades to monitor Terry’s activities. They catch and record Terry and Angie feeding the steroid-laced chickens to the alligators.
