Badass: The real Sealand's formation. It was formed when an absolutely batshit insane man, his mercenaries and several hundred 'subjects' stole an aquatic military base from pirate radio broadcaster Ronan O'Reilly and declared it the country of Sealand. Then, when England tried to deal with him through the navy, he fended them off with firearms, gasoline bombs and what his own wikipedia article describes as lunatic strength. From then on, he managed to get his imaginary country declared as a real country by basically shooting anyone who said that it wasn't.
Cute Shotaro Boy: Someday, Sealand will be a huge empire that even that jerk England will bow down to!
Has Two Papas: Sweden and Finland, though this is mostly fanon. Only Sweden was seen adopting Sealand; fans just incorporate Finland into the family scheme because of the whole "wife" thing. Admittedly, it is pretty cute.
Danshigakusei: Fair enough, since it's an English design and he's school age.
Verbal Tic: Sealand finishes most of his sentences with "desu yo", which lends his speech an emphatic tone.
Seborga
So you must be little Wy! Hmmm, maybe I'll hit on you after a couple hundred years go by.
Chivalrous Pervert: As seen in the quote above, he flirts with girls a lot but passes Wy for being too young for him. He still promises to hit on her when She Is All Grown Up.
Cloudcuckoolander: If one doesn't consider his introduction where he's stuck in a tree upside-down while ketchup drips from his forehead while still being awfully cheerful strange, then what is?
Dismotivation: Among all the Micronations he actually could try to be officially independent but... it's just too much work, you know?
Fan Nickname: The few "human names" seen around are "Paolo" or "Marcello".
Fun Personified: According to his profile he's "a cheerful, self-proclaim independent nation seated on a hilltop".
Tsundere: She insisted that it was a "coincidence" that she wore the dress Sealand told her to in Hetaween 2011, causing Seborga to comment that she takes after England.
Trademark Favorite Food: Baumkuchen is established as his favourite foodstuff in fanon because in his first appearance in the manga, he wonders if the dessert can be considered as art.
True Art: Seems to be moping about what is considered art.
If It's You, It's Okay: Implied, non-sexual and non-romantic example with America according to this new strip.◊ Unlike everybody else, he is so used to see Molossia's Nice Guy side that he is surprised to see the micronation as a Delinquent. Then again, acting tough would be no use since America is way much stronger than him...
Split Personality Makeover: He goes from regular Nice Guy to Delinquent in seconds when someone walks on his land. He is very embarrassed when his true face is seen and since he became friends with other micronations, which means he gets more visits from them, he gets prepared by changing into his tough-looking self every day.
Tsundere: He flips Sealand, Seborga and Wy off when they ask him to be their new friend, but runs back to join them as soon as they leave.
Principality of Hutt River
Paying your respects to me, your senior, is simple etiquette, yes?
Pimped Out Cape: Like the rest of his outfit, it is part of his home's regalia (see link above, not the one about bilbies, the one above it), even though it is, along with the sash, of another colour.
Purple is Powerful: When he appears in the (uncoloured) manga that introduced new micronations, Sealand comments on how he "looks like an amazing and important person". Then, at the end, Hima added coloured chibis of every micronation introduced, revealing Hutt's cape being purple, adding to the "amazing and important" effect. He is the first Australian micronation after all and the fact that he is quite developped compared to most micronations in general helps a lot too.
Sempai Kohai: Subverted. He claims to be Wy's sempai (translated as senior in scanlations), but Wy doesn't pay him much respect (see character quote): she is less than willing to greet him when she goes by his home and she even agrees with Molossia when he calls Hutt River a "lameass bastard". Still, Hutt's ridiculously snobby attitude doesn't help.
The Rival: Though he is more arrogant than dark, he is apparently one to Wy. She's very peeved when he comes in.
I'm Standing Right Here: Sealand screams in pain after learning he went back to be a Japanese citizen but Wy points out Nikko Nikko is just sitting behind him.
Only Six Faces: Wipe that paint and smirk off his face and he can pass for Latvia. In fact, when he was first introduced and we didn't know which nation he was, some fans called him Badass!Latvia or Seme!Latvia for the time being.
Reclusive Artist: His founding boss created the driftwood sculptures in his claimed land.
