About this AUEdit
How the characters themselves are portrayed usually differs, from being high schoolers to being students of San Fransokyo Tech and even full-on graduates. Whether or not the bot-fighting they partake in is legal or illegal may vary.
Whether or not this AU takes place in San Fransokyo (or at least in the same world) is not required, but is most common.
The Big FourEdit
In this AU, Hiccup is seen as the reigning champ, given his technical know-how translating to modern times. Given his timid nature, Hiccup would usually keep his botfighting hobby a secret from his personal life, drawing up a reputation as a result. His bot is mostly based off of Toothless, keeping the Night Fury as the core blueprint of its design.
In this AU, Jack (as his human self) is a botfighter that does it for fun and brings his sister along for support. His bot has been designed after a white rabbit-like design, an obvious reference to one of his guardian friends, Bunnymund.
In this AU, Merida possesses a brawler bot, her bot in particular drawing many influences from Scottish culture with bears as a primary influence in its design. Since botfighting has a "questionable legitimacy" due to spectators and other botfighters betting on the fights, Merida keeps her hobby and the bot she uses in it a secret from her mother; as she knows that Elinor would not approve the sport her daughter takes part in or the people she hangs out with at them.
In this AU, Rapunzel is a botfighter who's robot has been designed after a chameleon-like design, an obvious reference to her animal friend Pascal. Since her father is shown to be overprotective of his daughter in Tangled: Before Ever After and its follow-up series, Rapunzel keeps her botfighting hobby a secret from him.
Since Hiro is already a student at San Fransokyo Tech and spent time in the botfight fighting ring, he is usually portrayed as himself, as well as a fulltime botfighter and reigning champ with Megabot by his side.
Tooth's bot is mostly based on her fairies or their hummingbird like appearance and features. She is mostly seen having more than one bot at her side, and is commonly placed as a human in the AU.
In this AU, Astrid is a botfighter that hopes to go up against the champ and that her bot would someday beat his. Her bot is mostly based off of Stormfly or a blue bird, the form that the Nadder is sometimes given in modern crossovers.
In this AU, Elsa possesses a bot that has an elegant and a human-like design to it. Elsa mostly takes part in the Botfights as an escape from her life and the focus she uses in the fights allows her to keep her mind off of some things that have been troubling her of late, like trying to live up to her father, being the person that many expect her to be and her worries for Anna.
Anna mostly attends the botfights to spend time with Elsa and to cheer her on. Even when she is mostly seen watching the fights rather than taking part in them; she only joins in the when she feels that she wants to give it ago and with bots that wouldn't badly damage hers. Her bot is mostly based off of Olaf.
Since Varian is sometimes viewed as a Hiro-like character (mostly in the Tangled universe of its TV series and the Tangled Hero 6 crossover) and the skills that the young alchemist used to build a reverse-engineered version of the Guardian Automaton, he encountered in the underground tunnel system into an army of them, can easily place him as a botfighter. With a miniature version of one of the automatons or the giant machine that was altered from them as the bot he uses in the underground, illegal botfights. His bot can even be based off of Rudiger, that can transform into a robot version of the raccoon's beast form; bit like how Hiro's botfighting bot changes its face to switch Megabot's playful mode (yellow face) with its battle mode (red face).
While the Once-ler is seen as one of the attending botfighters, his Greed-ler side has him betting on the fights rather than taking part in them. The bot that he uses in the fight will most likely be based on the Lorax, one of the animals (like Pipsqueak) living in the Truffula Forest or has it designed after the axe-chopping machines that he and his family used to cut down the Truffula Trees.
