Maisie Bramble is introduced early in "The Sea Beast" as a bit of a rule breaker.
Obsessed with the seafaring hunters who traverse oceans tracking and killing giant sea monsters, Maisie (voiced by Zaris-Angel Hator) is first shown regaling her fellow orphans with stories about these warriors' heroics by candlelight before the children are caught breaking curfew. It's also hinted that she routinely breaks out of the children's home.
Maisie "is just a force of nature," said "The Sea Beast" director Chris Williams during a recent phone call. She's "a character that is absolutely determined to go after what she wants. And if she sees an obstacle, she'll go through it, around it, under it, but she will achieve what she's after."
