Big Screwed-Up Family: Due to the nature of the British Empire, they are often portrayed this way in fanworks.
Blade on a Stick: During "America Cleans Out The Storage", England and America face off with bayonets.
Team Dad: In a metaphorical (literal?) sense England's the older adoptive brother of America (and Sealand and presumably most of the commonwealth). Former older brother, anyway. It's complicated.
Adaptation Dye Job: Has lighter blond hair with darker tips in manga artwork, but the anime gives him a uniform dark blond shade. His eyes also changed from being violet (or light blue) to a deep blue. Both changes make him look even more like America.
Heavy Sleeper: Seems to be narcoleptic, as one of the webcomic strips has him speaking to someone else and then both fall asleep randomly. See his quote as well.
"The Reason You Suck" Speech: America and Canada argue. Canada has a 'not so quiet' moment and wins. After three hours, England cuts him off out of mercy for a collapsing America.
Sensitive Guy and Manly Man: America and Canada's sibling relationship is often portrayed as this, with America as the Manly Man and Canada as the Sensitive Guy.
When interacting with Cuba they have this dynamic as well.
Sibling Yin-Yang: With his brother America. Canada is meek and sensitive while America is outgoing and has occasional bouts of arrogance.
The Stoner: In Fanon, due to the country's rather laid back stance on cannabis in Real Lifeand to the extremely good diplomatic relationships with the otherfanon stoner, Netherlands.
The Strategist: Himaruya remarked that he was a good tactician.
The Unfavorite: Canada has always been overshadowed by America ever since they were little. As soon as England seemed to be paying more attention to Canada, America came along and took his attention back.
In fact, poor Canada is usually treated as a non-entity - people either forget who he is or don't even notice him. (In one strip Russia spends a whole meeting sitting in his lap because he didn't notice that Canada was already sitting in the chair. Later Russia comments to Belarus on how comfortable his chair was.)
Annoying Younger Sibling: An adopted one of sorts towards England and France. But mostly England.
Bare Your Midriff: In a few chibi sketches where she wears an outfit reminiscent of pirates.
Big Eater: Implied. In the 2010 Christmas Bloodbath, she was willing to eat Finland's cooking, and even asked for him to send her food in exchange for a photo.
The Ditz: She has a few moments. So far, she seems to be the spaciest of all the female characters, especially in the Christmas events, where she has texted Finland just to ask how he would describe ants being all over the place and tries to play in the snow as if it were sand.
Seychelles: Ah, can I eat the fish? It's a fresh fish. [...] Or would a flying fish be better? Is it?
Fan Nickname: The fandom hasn't really settled on a human name for her the way it has for Taiwan or Netherlands, but "Leonie", "Michelle" and "Angelique" are the most common human names for her in fanworks.
Foot Focus: Illustrations show her as either wearing sandals or going barefoot.
Gossipy Hens: Seems to have shades of this in volume four when she has a lot of trouble keeping it to herself that a certain royal couple would be spending their honeymoon at her place.
Joshikousei: She's the star of Gakuen Hetalia, as already mentioned.
New Transfer Student: In the Gakuen Hetalia game, France convinces her to join the World Academy. When she draws her national crest on the chalkboard, the other members of her Africa Class laugh so hard at how cheesy it is they need to be taken to the school infirmary.
Only Sane Man: Averted. In Gakuen Hetalia, Seychelles attempts to put a curse on England, only to have him reveal himself as a lover of black magic as he starts begging for her to teach him. This causes Seychelles to think on how strange everyone in World Academy W is, not realizing that she is in fact just as weird as everyone else.
Plucky Girl: As attested by the quote mentioned above.
Seychelles: I'll say my name and everything straight up when I prank call England. I'll pretend to talk about the TV instruction manual with him.
Sassy Black Woman: The more positive side of this trope. She occasionally says snarky things about her (at the time) boss England as well, and is said to have dumped France in Christmas. Look below as well.
Shorttank: Seems to be getting this treatment in a few sketches as of late.
Although sometimes it's portrayed more as her Companion Cube.
Tsundere: In Gakuen Hetalia, she's a Type B that goes from demure and polite to screaming or swearing as soon as England or France push her too far, either by being bossy (England) or by groping her (France).
In the original Gakuen Hetalia script, one of the "bad endings" (the one where she joins the Axis) drives it very straight to the point, as it finished with Seychelles screaming and swearing that she'll kill England the next time they meet.
To England (After he clamps a dog collar on her and declares her his colony): LIKE HELL I WILL YOU EYEBROW BASTAAARD!
As well, an initial design shows Seychelles with one very bushy eyebrow and one normal one. This sketch also has her trademark ribbons missing.
Why Did It Have To Be Snow?: She seems to hate the cold in the 2011 Bloodbath, nearly passing out because of it. Justified because of her Real Life climate.
Fan Nickname: "Bruce" and "Adam" are the most commonly used names for him. Himaruya has mentioned the following name suggestions sent by fans: Ralph, Christian, Kyle, and Jett.
Ah, no… I was playing soccer with the kids and the ball hit Mr. Mulema’s house.
The Beautiful Game: He seems to really love soccer football, to the point that when he's kidnapped in the Hetalia Bloodbath 2010 the people in his country start to lose interest in the game.
He also teaches it to the world's smallest primate when he was taking care of one for another nation.
Idiot Hair: Appears to have two in the same style as New Zealand; however, since they were dressed as a sheep in their only appearance, it may have been part of the costume.
The Faceless: For the moment; in their only appearance they were seen from the back.
