A Typhlosion, Hestia is tall and intimidating looking due to her intense gaze, but in reality is quite endearing and a natural caretaker of others, leading to popularity among others in her area.
Her flames themselves have a similar effect to the Hisuan Variant of her species, in that her flames have a soothing, comforting effect when used outside of battle that help ease one's worries.
(People who know her personally attest to her being quite plush and the greatest warming pillow you could ever lay on)
