Bea
The Kentish Karateka
A lot of people have compared Bea to Toph. They're both incredibly skilled in martial arts, they're both buff as heck, they both walk barefoot everywhere, and they both had extremely strict, authoritarian parents.
But I can't say I agree with the comparison, because where Toph rebelled against her upbringing, Bea accepted it, and that makes all the difference. Her worldview and life goals couldn't be further from Toph's.
Where Toph wants freedom, discipline is Bea's foremost virtue. She's stubborn in all the best ways and can't stand the thought of giving up.
In her Twilight Wings short, it implies that her defeat against Leon has unsettled and frustrated her, and her response isn't just to review her mistakes, or train more at the gym, but to go as far away from society as possible and test herself against the elements and wild pokemon.
When a Gyrados outspeeds her sprint, she gets angry and runs even faster. When her Corviknight taxi is shaken by a sandstorm, she jumps out and walks the rest of the way. Even after she hurts her arm, she's still going, pushing herself, trying to transcend her limits. She tones down her intensity only after realizing her partner pokemon, who she cares about deeply, is starting to get worried for her safety.
I think this shows a lot how such a slight difference in parenting methods can have such huge repercussions. Toph's parents told her that she was small and weak, and she had to adhere to this strict lifestyle to keep her safe. But Bea's parents (presumably) told her that she was strong and capable, and that the purpose of their harsh training regimen was to bring out her full potential. So, trusting that such latent potential exists within her, she wants to do everything she can to realize it.
Bea could very easily have come to resent her lot in life, but she gladly took on the role of continuing the family business, which speaks to her mother and father's skill at parenting and how strong her relationship with them is.
In order for her to maintain her intense lifestyle, she has to have discipline, and since she's all grown up now, that discipline has to come from within. That's why she puts on such a tough, stoic exterior, not just in public, but in private too.
After her fans discover the existence of her sweet tooth, she starts to find it more difficult to enjoy her favorites, because she doesn't want to show 'weakness'. Considering her masterful physique, she probably eats way fewer sweets than most people, but the fact that she enjoys sweets at all considering how unhealthy they are might sometimes feel to her like a fault in discipline.
Her sweeter side isn't something she feels she
has to repress, but something she
wants to repress - not because she's ashamed of it, but because if she isn't tough, she can't live the way she wants to live. Thus, she reserves it for people she respects and trusts, and even then only in specific situations.
Bea is one of those girls who rarely smiles, but when she does, she lights up the whole room. It's really heartwarming to see.
If only Sword & Shield didn't suck so bad...
