History Characters / RubyGillmanTeenageKraken

* LateToTheAction: [[spoiler:Brill eventually catches up the seaport battle between the Gillman women against Queen Nerissa. Unfortunately, he arrives just as things died down. Though he finally gets the heartfelt hug from Grandmamah to compensate.]]

* ASMRVideo: Arthur has a hobby livestream web series involving bottled ships in this style. He speaks with low, whispering tone while carefully fiddling with the ship models inside. [[spoiler:He reveals to have made a bottled ship with a tiny sized version of Ruby's Kraken form protecting it, to honor his daughter's heroism.]]

* AnnoyingYoungerSibling: He has his tendencies to be overly nosy or confrontational with his older sister Ruby. For example, he extends his legs to try and tower Ruby in the family huddle, only for Ruby to quickly adjust down to his usual pint size. The closest he's gotten to being unbearable to Ruby was his insensitive questions about her new Kraken abilities, where Ruby impulsively threatens to strangle him ''with'' her superpowered tentacles.

* AllAnimalsAreDogs: Nessie, despite being an aquatic creature, behaves similarly to a domesticated dog. She whimpers, pants, and wears a dog collar. Concept art featuring her goes further by having him be walked around like a dog.

* AllLovingHero: Despite the history between Mermaids and Krakens, Ruby hopes for peace between them. [[spoiler:Even after learning Chelsea's true nature, she still offers her a LastSecondChance if she'll hand over the Trident peacefully. After Chelsea refuses, but Ruby still doesn't allow Grandmamah to kill her.]]
** She proved to be this even before she learned of the whole Mermaid/Kraken conflict, as when she was younger, she took care of beached whale for seven hours before the tide brought him back in.

* CharacterDevelopment: Starts out as a insecure teenage girl, then grows over the course of the film to a confident hero.

* EndearinglyDorky: Probably a reason Connor is charmed for Ruby.

* PurpleIsPowerful: Ruby's Giant Kraken form changes her skin tone from light blue to purple. This form shown to quite formidable, thanks to its extreme size and incredible abilities.

* SingleWomanSeeksGoodMan: Probably the reason she fell in love with Connor. Besides her squad solitary of friends, Connor is the only student who treats her like a person with kindness and complements instead of seeing her like a freak.
* SmittenTeenageGirl: Ruby has a crush on Connor, a fairly nice skater boy who she helps as her math tutor.

* ActionPet: Nessie has his moments of being in action. He disguised himself with Christmas lights at sea, pretending to be a glowing kraken, in order to throw off Gordon Lighthouse's trail in trying to capture the giant Kraken version of Ruby.
* AllAnimalsAreDogs: Nessie, despite being an aquatic creature, behaves similarly to a domesticated dog. He whimpers, pants, and wears a dog collar. Concept art featuring him goes further by having him be walked around like a dog.

The family sea pet of the Gillmans, who particularly have a fondness for Ruby.

An awkward and shy high school junior who's a mathlete, tutor, and has an interest in marine life. Her organized life becomes disrupted upon accidentally activating her hidden royal Kraken abilities.

* AllLovingHero: Despite the history between Mermaids and Krakens, Ruby hopes for peace between them. Even after learning Chelsea's true nature, she still offers her a LastSecondChance if she'll hand over the Trident peacefully. After Chelsea refuses, Ruby still doesn't allow Grandmamah to kill her.

* ArchEnemy: Becomes one to Chelsea over time. [[spoiler:Chelsea already had one in Ruby's own mom]].

* ThouShaltNotKill: She won't kill [[spoiler: Nerissa]] or allow her grandmother to do it. Her plan for ending their conflict is to destroy the Trident of Oceanus, preventing [[spoiler: Nerissa]] from carrying out her plan and leaving no further reason to fight, while also assuring that Chelsea can't transform back into said form.

* TheAce: In the film, she's praised for being a successful real estate agent. [[spoiler: Likewise, when she was still a princess, her mother praised her for singlehandedly turning the tides on the original Mermaid and Kraken war. Agatha seemingly defeated Nerissa the Mermaid Queen long ago (when in reality she went into hiding and turned into her human form Chelsea), and sealed the Trident to prevent the evil Mermaid Queen from acquiring it. She also helps defend Ruby during the FinalBattle and helps her destroy the Trident to defeat Nerissa.]]

* SapientPet: They're very perceptive, despite being considered akin to a non-talking dog. Nessie primarily looks out for Ruby in various human-like ways, such as pretending to be a sleeping Ruby under bed sheets, or sniffing out and pantomiming why Ruby's saltwater breath and exposure will possibly get her mother's attention.

* {{Expy}}: of Batholzor Hellman from WesternAnimation/{{NeighborsFromHell}}. both are strict, both are [[MyBelovedSmother Beloved Smothers]] and both want their children to not be too curious.

* {{Expy}}: of Daniela Paguro from WesternAnimation/{{Luca}}. both are strict, both are [[MyBelovedSmother Beloved Smothers]] and both want their children to not be too curious.

* FantasyForbiddingMother: Agatha generally wants to stir away Ruby from getting too intrigued about the secrets of the seas. In the opening act, she derides Ruby getting into human-written marine biology books as nonsense. This extends to preventing Ruby from learning about her royal family more than she absolutely has to, when circumstances force her hand. She insists on wanting her children to live a normal human life. [[spoiler:She finally grows out of this after the battle with Chelsea/Nerissa ends with her and her daughter becoming Oceanside's Kraken protectors.]]

* MamaBear: [[spoiler: When calling out on her mother's strict and controlling behavior, Agatha points out the difference between their fighting spirits: Grandmamah loves to fight for the sake of it (thus endangering her fellow Krakens), while Agatha explicitly fights to defend her children and husband. This is shown in the climax when she helps defend her daughter Ruby from harm's way of Queen Nerissa, and plans to resume her rematch with her. Though Ruby is forced back into the fight when both Agatha and Grandmamah are put on the ropes. She also throws a house at Nerissa when she tries to harm Sam for defending Ruby.]]

** After revealing her true colors to Ruby, she taunts her by calling her a naive teenager for helping her get the Trident of Oceanus.

** She severely damaged the house of the soon-to-be expecting married couple that Agatha just sold to them earlier in the film.
