Seychelles is described as a country girl with too big of a heart and some sloppiness. She can't cook on her own, and laments over her high cost of living. Her language is an odd mixture of French, English, and many others.
She has only made one major appearance in the comic to date (in We're Shipwrecked Too!), though she also makes a cameo in Comic Diary 9, where she rants about people not even knowing of her existence (after overhearing the other characters mention their countries' stereotypes and reputations).
In her Gakuen appearance, she seems to be a tsundere-type character and is conflicted about her feelings for both France and England.


In the Gakuen Hetalia universe, it is revealed (via flashback) that France helped raise her as a child, while in the present day he carries a strong affection for her and attempts to undress and grope her, much to her shock and embarrassment, apparently desperate to see what her body has become like.
Their relationship in the mainstream Hetalia universe has not been mentioned, outside of France appearing with her in Shipwrecked and an illustration in Christmas Rampage 2007, which depicts him groping Seychelles yet again.
