ok but this is such a good q? i actually gotta sit and think about it

i can see Raiden and Folinic getting a paired BoC or Raythean skins, possibly one of a mission where they both were on together though if you want a less depression filled skin set i wouldn't mind a gym buddies marthe pair of skins

Cascade and Platinum would get Vitafield or Icefield cause i can see them traveling together to places as hinted in Plat's lines where she wants to go somewhere after Rhodes, probably something like what Exusiai/Carnelian's got in terms of outfits

Angelina and Empyrean could totally going casual in Cambrian, cambrian doesn't let down fr though i also really like the concept of them both getting Rhodes Kitchen one's? like ot would be Empy's bake house where Ange samples or something

that's for OCxCanon at least, for canonxcanon i do want fiamos to have matching BoC or Cambrian and RosMiya rhodes kitchen...

honestly all of them have weapons (at least arknights wise) so ill list em and add details if needed :) also ill put ref pics on the twt postlol

starting with Dr.Zheng, while usually they don't appear armed they do have 2 short bo staffs which can combined to make 1 long staff which can be manifested at will (like Nian's greatsword if you will) it was actually forged by Nian hence the manifestation ability!

Raiden fights with a custom built weapon, essentially a fusion of brass knuckles and pathera claws

Cascade just goes with an assortment of knifes

Empyrean has 2 weapons on hand at times, a single daggar with special ingravings and an AR-15 with a scope

Dice also has 2 weapons but this time it's a casting staff with modifications to suit their tastes and a Daisho set

im still figuring out what to give Teumesios but since i play for them to be an Agent Vanguard its probably gonna be either a pair of weapons that can do close and ranged combat or just one that fits both
