We haven't roleplayed them yet but Kalos!Kyder
Gives nose/forehead kisses: Ryder. He’s taller, and he’s just more into the cutesy constant affection than Kitty is.
Gets jealous the most: Kitty. She’s still not really a huge fan of Ryder hanging out with Marley, even though he long ago chose Kitty over his former crush.
Picks the other up from the bar when they’re too drunk to drive: Kitty. She’s too smart to get that wasted on her own without having a way to get home, but when Ryder gets drunk she (grumblingly) goes to get him.
Takes care of on sick days: Ryder, although Kitty mostly has to tell him what to do, since his idea of taking care of her is mostly just giving hugs and watching movies.
Drags the other person out into the water on beach day: Ryder. He loves to splash around and build sandcastles and go body surfing and whatever, whereas on her own Kitty would be happy to just sit on a towel and soak up the sun.
Gives unprompted massages: Ryder. Kitty’s the one who gets more worked up and angry about things, so Ryder spontaneously starts rubbing her shoulders to get her to be less tense
Drives/rides shotgun: Kitty. She doesn’t trust Ryder to be in charge when he’s prone to breaking out dancing to Spice Girls songs even when he’s the one behind the wheel.
Brings the other lunch at work: Kitty, because she knows Ryder forgets a lot and while she gives him a hard time about it she also wants to make sure he’s fed and taken care of
Has the better parental relationship: They both have their ups and downs with their parents, but they’re more likely to spend holidays with Ryder’s family because the Pokemon daycare center is awesome.
Tries to start role-playing in bed: Ryder probably suggests something stupid after they’ve gotten comfortable with each other
Embarrassingly drunk dancer: Ryder’s always embarrassing when he dances, but Kitty busts out some interesting moves when she gets really drunk, too -- she’ll even do the sprinkler with him if they’re drunk enough.
Still cries watching Titanic: Ryder loses focus during Titanic because it’s long and there’s not a lot of action, but he catches Kitty sniffling during it and plays with her hair or something until she’s done being sad
Firmly believes in couples costumes: Ryder. Kitty’s not totally opposed to the idae but she pretends she is because Ryder’s ideas are usually so ridiculous, and if she acts like she doesn’t want a couple’s costume at all it seems like she’s compromising when she proposes an idea and ends up getting her way in the end.
Breaks the expensive gift rule during Christmas: Kitty. She’s not as good at being loving and affectionate on a day to day basis so she makes up for it by trying to remind Ryder she loves him with a big Christmas gift.
Makes the other eat breakfast: Ryder. He loves food too much to skip a meal, but he makes sure there’s extra for Kitty so she doesn’t try to skip it and go right into her day
Remembers anniversaries: Both. Kitty’s just more organized but Ryder’s such a romantic that he wouldn’t forget a big day
Brings up having kids: Ryder, for sure.
