I have no self control and no sense of a queue, so here: Flames, personalities, and influences.
(right, so I’m going to do these in colour order it’ll just be easier for me. And only Sky-aligned, because there’s only one example for each Earth-aligned/Other. I’ll cover Sky last, because that’ll probably be the longest.)
((before I get into Flame typing I want to go over Classic and Inverse, which just refer to personality traits. Classic Flames are those that fit the idea of what a Flame is, based off of the Vongola First Gen. Inverse are Actives who are opposite to that stereotype. Personally, I figure it’s like a scale, Classic to Inverse, and any Active Flame fits somewhere on the scale.))
First of all, Storms. The first Storm introduced is Gokudera (who isn’t a great example due to his five Flames, but more on that later.) When he’s introduced, he’s presented as angry and confrontational, not to mention rash. After he fights (and loses to) Tsuna, that anger fades, becoming more of a running joke, and is replaced with loyalty. This is the basis of what I consider a Classic Storm- rash, confrontational, and loyal to a person. These traits are seen both in Xanxus (as a Stormy Sky) and I-Pin (as a canon Sunny Storm from the card games). An Inverse Storm (ie. Fon) is the opposite of this- calm, placating, and loyal to an ideal. You can also see the features of an Inverse Storm in Fuuta, who, by the card games, is a Storm.
Then there are Sun Flames. Again, starting with the Vongola Tenth Gen, Ryohei. Ryohei is incredibly energetic and constantly on the move, as well as loud. From this, Classic Suns seem to be energetic, enthusiastic, and eccentric. We see all three of these traits in Reborn, and, to a lesser extent, in Lussaria. There aren’t actually any characters that could be considered an Inverse Sun, though it can be assumed they would be laid back, and relaxed, but still show the eccentricities inherent to this Flame type.
Next, Lightnings. The first Lightning of the series (canon to manga/anime) is Lambo. He’s loud, he draws attention to himself, and he has a habit of pissing people off. He’s also generally obsessed with two things- weapons, and candy. This obsession can be seen in other Lightning characters, such as Verde, who seems to obsess over science, and Levi, who (from canon and fanon) seems to obsess over Xanxus’ wellbeing and happiness. Classic Lightnings can be summed up to this: loud, eye-catching, and obsessive. The first Lightning actually shown in the anime/manga, however, is only considered a Lightning in the card games- Sawada Nana. Nana is a cliche Inverse Lightning- quiet, obsessive, and to a certain degree, ordinary. She obsessed over her life as a housewife, she keeps her head down, and she gets through it one day at a time.
Rain is an interesting Flame, and Rains are an interesting bunch. Between Classics and Inverses, Rains seem to be a favourite of the fandom, either to torture or ship. The Classic Rain this is based off of is Yamamoto. He’s eager, and happy, and he treats danger like a game. He’s considered one of the more (in-universe) popular characters. Insults seem to run off him like, well, rain on a stone. He’s easygoing, and his father (considered a Rain by the card games) is too. Classic Rains are optimistic, easygoing, and often draw attention to themselves. Inverse Rains, like Squalo, are more similar to Classic Storms, in that they are rash and quick to judge. Squalo makes decisions based on split-second moments, and while he’s optimistic, he is also a bit narcissistic. Inverse Rains are optimistic, rash, and command attention, almost demanding it.
Mists are, well. Mists. Chrome and Mukuro are the basis for this theory. Both are generally rather trickster-like, concealing their actions and aims until the very last minute (see: Lancia taking the fall instead of Mukuro, Chrome not sharing that shes possessed until the battle begins.) Classic Mists are deceptive, secretive, and sly. There are very few characters i would consider to be Inverse Mists, but Shamal is one of those few (in the card games at least). He’s far more open than Chrome or Mukuro, and rather straightforward about his policy on only treating women. He is, however, as sly as Classic Mists, shown through the consistent use of his mosquitoes to inflict diseases on people without their knowledge. We can tell that Inverse Mists are far more open about their intentions, and slightly less secretive, though still as sly as Classics.
In the fandom, Clouds are the one where Inverse/Classic dynamics show up the most, with canon Clouds ranging from Skull to Hibari. Hibari is considered to the the extreme example of a Classic Cloud, taking the stereotype to a point of near-insanity. He’s quick to fight, and loves to do so, while simultaneously wanting constant silence. He hates the presence of others around him, or just in general, often breaking up groups of students. Hibari also takes on the title of protector of Namimori, and holds the school in an iron grip with the DC. Classic Clouds seem to be brash, solitary, and territorial over a place or set of objects. Now, if Hibari is the extreme example of a Classic Cloud, Skull is the opposite- an extreme example of an Inverse Cloud. Skull is loud, childish, and bright. Pre-curse, he was a stuntman, a position that puts him right in the public eye and most likely surrounded by adoring fans. He seems to prefer peace to fighting (or maybe just prefers not being shot at). From this, we can infer that Inverse Clouds are more meek than Classics, and thrive on social interaction. Inverse Clouds are also territorial, though over a group of people or concept (ie. Skull and immortality/his career)
Finally, Skies. For our Classic Sky, we’ll be using Tsuna. Tsuna, in canon, is the ‘straight man’ of the group- hes the only one who sees whats wrong with the whole scenario, which means we’ll have to factor that out. He also isn’t combative, preferring to take the peaceful route in confrontation, which is shown time and again throughout the series, first with Gokudera, and then Haru, and Mukuro ect. Tsuna is quite forgiving, and generally wants to see the best in people. Skies also draw attention, most likely due to the Harmony factor. Tsuna does this pre-canon by attracting bullies, and during canon by finding Guardians. On the topic of Guardians, Tsuna is shown to be relatively protective of people he cares about- often, their injuries are the only thing that drives him to fight. From this, we can assume Classic Skies are peaceful, forgiving, and protective of their people. Often, Xanxus is portrayed as an Inverse Sky. However, if you look, these attributes are shown by Xanxus, albeit combined with the nature of a Classic Storm. For an Inverse Sky, i would say Timoteo. With his position as Nono, he needs to be willing to fight, and he certainly isn’t forgiving, having to be persuaded by Iemitsu to spare Xanxus’ life after the Cradle Incident (though the alternative isn’t much better).He is, however, protective of people he considers under his protection, refusing to escalate situations he knows he can’t win (Inheritance Arc). We can infer that an Inverse Sky is combative and merciless, though still protective of their people.
For each of these, however, remember that Classic/Inverse elements are considered a scale, and that while characters can have these attributes, often it’ll be a mix, or some will be stronger than others. Also, these are only Flame-influenced personality traits- a character is far more than three words of a stereotype. Similarly, a lot of characters have more than one Flame, and that would effect these traits as well.
