|Occupation||Ruler of the Intraterrestrials|
|Residence||Center of the Earth|
|First Episode||To Smell and Back|
Queen Gabnidine is the ruler of the "Intraterrestrials" in the story Howard tells in "To Smell and Back." She is the force behind the plan to extract the Ninja's "hero" in order to restore Magman, the hero who defends the Intraterrestrials from "the evil mantle-dwellers." She has the odd verbal tic of ending nearly all her sentences with a long drawn-out, "Riiiiiiiiiiiiiiight?"
Like all the Intraterrestrials, Gabnidine is green, with a crab-like four-legged abdomen, and a humanoid two-armed thorax and head. Unlike the others, she has a long hook-nose, and, whereas the others have yellow sclerae ("whites of the eye") and black pupils, she has white sclerae and yellow irises/pupils; she also wears a very tall crown and carries a scepter.
- She is not a real person in-universe, but exists only as the antagonist in the story Howard makes up for an English assignment from Mr. Bannister.
- Though a female, she is played by a male voice-actor, veteran actor-comedian Jon Lovitz, several of whose characters are known for catch-phrases like the Queen's, "Riiiiiiiiiight?"
- Somehow she knows who Howard is, declaring, "Howard and the Ninja defeated us — but mostly Howard!" A creature dwelling at the center of the Earth would be unlikely to know any one of the billions of people on the surface, particularly a random, not particularly distinguished 9th grader; this is one of many indications that Howard's story is wildly unlikely, even in-universe.
