    Duncan Rosenblatt
Voiced by: Jesse Head

Duncan Rosenblatt, a high school teen with a typical suburban soccer mom who wants him to get into a good college and a 120-foot firebreathing dragon father, who wants him to follow in his foot steps—conquering the Earth and inheriting the throne of King of Kaiju; they share custody. Like every other teenager, he struggles to fit in with his peers. His being half-dragon further complicates matters. Duncan is completely resigned to his outcast status and has really stopped caring all that much. His awkward family arrangement forces him and his mother to move a lot.

    Margaret Rosenblatt
Voiced by: Dana Delany

Margaret Rosenblatt, is Duncan's human mom and Belloc's wife, who just wants her son to have a normal life...or as close to normal as he can get.

  • Action Mom: Margaret, in the movie at least. Flies jets, shoots, threatens Belloc and means it.
  • Dude Magnet: Won the love of a Kaiju and the unwanted kind from Barnes.
  • Interspecies Romance: Margaret (human) had a relationship with Belloc (Kaiju).
  • Mama Bear: She'll do anything for her son. In a more subdued example, Margaret was rightfully pissed at both Kenny and Jenna for their actions toward her son (the former for revealing Duncan's heritage out of a jealous rage and the latter for brushing her son off.)
  • Morality Pet: She probably is the only true person (besides Duncan) to have a positive effect on Belloc.
  • Nice Girl: She has a friendly personality.


Belloc is the king of an ancient race of monsters known as Kaiju. He is the father of Duncan Rosenblatt, the husband of Margaret Rosenblatt, and King of all Kaiju.

  • Interspecies Romance: Belloc (Kaiju) had a relationship with Margaret (human).
  • Jerk with a Heart of Gold: There's no Belloc can be a jerkass, but he does care about his family.
  • Kick the Dog: He needlessly steps on Isabel. It wasn't strong enough to kill her, but it was an unnecessarily petty action to do.
  • Papa Wolf: Let himself be captured so Duncan could be safe from harm.

    Agent "Blitz" Barnes
Voiced by: Reed Diamond

An undercover MEGTAF agent posing as the high school gym teacher, “Blitz” Barnes watches over Duncan to make sure he keeps a low profile.

    Jenna Shwartzendruber
Voiced by: Amy Davidson

Jenna Shwartzendruber is the Student Council President of Duncan's school and his primary love interest.

  • Betty and Veronica: The "Veronica" (Love at First Sight for Duncan and the Student Council President of their school) to Isabel's "Betty" (a new friend for Duncan, low on their school's social status, and a kaiju expert) for Duncan's "Archie".
  • Dude Magnet: Just ask Duncan, Troy, and a couple of her other male classmates.
  • Interspecies Romance: She (a human) is possibly developing a romance with Duncan (a kaiju/human hybrid).
  • My God, What Have I Done?: Her reaction after she snubs Duncan at the homecoming after learning about his kaiju ancestry.
  • Nice Girl: Jenna is a overall friendly person and was regretful over snubbing Duncan after learning over him being the son of the Kaiju King.
  • Student Council President: Of her school.
  • Tomboy and Girly Girl: The Girly Girl (wears feminine clothing and abhors dissecting frogs) to Isabel's Tomboy (wears masculine clothing and is a resident kaiju fangirl).
  • Took a Level in Badass: Went from being terrified and running away from kaiju to actively shooting one down with a gun to protect Duncan.

    Isabel Vasques
Voiced by: Tia Texada

Isabel Vasques is a close friend of Duncan's, and has a romantic interest in him. She is also the best friend of Kenny Rogers.

  • Ambiguously Brown: Given her dark skin and full name, she's most likely of Hispanic descent.
  • Betty and Veronica:
    • The "Betty" (a new friend for Duncan, low on their school's social status, and a kaiju expert) to Jenna's "Veronica" (Love at First Sight for Duncan and the Student Council President of their school) for Duncan's "Archie".
    • The "Archie" for Kenny's "Betty" (the resident "loser" of the school and Isabel's long-time friend) and Duncan's "Veronica" (mysterious son of the Kaiju King).
  • Fangirl: Her profile states she's "a quintessential Kaiju fangirl. She spends most of her time tracking MEGTAF reports and sharpening her Kaiju expertise".
  • Hopeless Suitor: She has a crush on Duncan, but he's interested in Jenna.
  • Loving a Shadow: Discussed. In a fit of jealous rage, Kenny states that the only reason Isabel is interested in Duncan is because she's a kaiju fangirl and Duncan's the son of the Kaiju King. Whether this is true or not, is up in the air.
  • Oblivious to Love: Doesn't know that Kenny has a crush on her.
  • Tomboy and Girly Girl: The Tomboy (wears masculine clothing and is a resident kaiju fangirl) to Jenna's Girly Girl (wears feminine clothing and abhors dissecting frogs).

    Kenny Rogers
Voiced by: Dante Basco

Kenny Rogers is a friend of Duncan Rosenblatt. He is also best friends with Isabel Vasques, who he has a one-sided infatuation with.

  • All of the Other Reindeer: Kenny is frequently picked on by Troy and the other jocks. Thankfully, he has Isabel and Duncan as friends.
  • Betty and Veronica: The "Betty" (the resident "loser" of the school and Isabel's long-time friend) to Duncan's "Veronica" (mysterious son of the Kaiju King) for Isabel's "Archie".
  • Crazy Jealous Guy: Really didn't like the idea of Duncan showing an interest in Isabel or vice versa.
  • Goth: Implied with his choice of dark clothing.
  • Hopeless Suitor: He has a crush on Isabel, but she's interested in Duncan.
  • Jerk with a Heart of Gold: Rats out Duncan's true heritage out of jealousy because of Isabel's romantic interest in him. Later, Kenny apologizes for what he did, immediately after luring a Kaiju away to protect Isabel.
  • Minor Living Alone: Kenny's profile did state he was "virtually parent-less".
  • Shout-Out: His entire name is one to the famous country singer.

    Troy Adams
Voiced by: Josh Keaton

Troy Adams is "king of the jocks" and "alpha bully". Troy's Gang instantly targets Duncan. He and Jenna used to date, but he just doesn't understand that their relationship is in the past tense.

  • Big Man on Campus: Gives off this vibe. Though how universally straight he plays this trope varies from student to student.
  • Curtains Match The Windows: Matching brown hair and eyes.
  • Freudian Excuse: After seeing his aggressive father, it's no wonder as to where Troy gets his antagonistic personality from.
  • Jerk Jock: "King of the jocks and alpha bully".
  • Le Parkour: Though he's no real match for Duncan in this department (or any other for that matter), he does get props for managing to keep up with him in a school-wide chase.
  • Pet the Dog: There are moments in the movie that show Troy isn't a complete jerk.
    • He warns Jenna stay away from Duncan. This isn't because of a Crazy Jealous Guy personality, but because he legitimately thinks Duncan is a threat and doesn't want Duncan to hurt her.
    • After Kenny, the very same kid he bullied earlier, is injured luring away a kaiju, Troy goes over to him in order to help him up and get him away from the monster.
