I've got 2/4 of the Chosen Four figured out...

I'm gonna spill out some ideas now. Also, I'm gonna start with Jeff because I found that he was easier to figure out, and because my notes for Paula is mainly just me trying to figure her out xd

JEFF

• Sticking to canon: he's "not very strong, really near-sighted, kind of shy, and [tends] to be a little reckless". Good with gadgets, machines, and deadly firearms. Easy.
• I don't know how stoic I want him to be. I don't want him to be totally emotionless, so I'll make just him a little stoic. Stoic enough that he's no fun to annoy, but not so much that he's no fun to be around either.
• I want him to have somewhat violent tendancies and itches for action. Particularly inspired by this clip and this old comic I made based off a scene from the same anime xD
• I feel like he'd be a little scheming and likes to take advantage of situations. I remember so many years ago, I read this one fanfic of the zodiac signs babysitting a kid and everyone except for Capricorn and Scorpio agreed to ditch the job and go to a party/club. Capricorn whispered to Scorpio, "Okay. Once this is done, we'll split the money". I dunno, I feel like that's something my version of Jeff would do xD
• Despite his introvertedness and overall nerdiness, he also loves getting into action (alonside the rest of the four)
• He's the kind of guy to keep a notebook wherever he goes. He takes note of everything, even if it's just some fact/quote that he'll never use ever. He just puts anything that interests him.
• You know what, I should just make entire posts dedicated to headcanons now. I think I've just figured out my version of Jeff

PAULA (part 1)

• I feel like Paula's one of the hardest to figure out, so watch my thinking process here xD
• Also, there's a LOT of thoughts here, which is why this is a Part 1

• It's kind of easy for the others because they fall under pretty obvious archetypes: dumb jock/moma's boy, nerd, and (from a Western/American point of view) royal from the "mysterious" East. 
• Paula's just... "girl", and I know there are a ton of types of girls. You'll notice that everywhere you look, the portrayal of Paula's personality in fanart varies quite a bit.
• Here are some Paula variations:
• Sweet, soft and innocent. A very shy, and quiet girl. (Honestly, this is more how I like to characterise Ana) Bonus: an innocent smile paired with the line "you have no idea how powerful I am" xD
• Feels like the only mature one of the group, has to clean up after everyone else, the stressed "mom friend" making sure nobody's doing anything stupid, under a lot of pressure to prove herself, being the only girl of the group.
• The kind of typical old-school "girly girl" who writes to her "dear diary" every night, thinks about boys and enjoys gossip. But, mess with her, her hair, or her teddybear, and you're getting set ablaze. Excited to get in on the action.
• I dunno if this fits under the same category as the above or deserves its own one... But I'm thinking of the archetype of like the one girl in the main enseble of a shounen action-adventure anime xd I dunno where to start when it comes to listing adjectives here
• Ok, now I dunno if I'm listing what I remember seeing or if I'm just making stuff up as I go, so I'll stop
• Okay, HONOURABLE MENTION: I've only seen this like once, but I love this portrayal a lot... Tomboy Paula. Literally just another "dude" but with pretty hair and a pink dress. Now that's she's away from home, she can finally get her hands in the dirt
• To be continued...
