i could see dilly being in the early seasons of RWBY as a faunus! he's around the same age as most of the main cast, and would fit right in what with the dorkiness.

LMAO you're right on the money! kiko was made for a 2-year long campaign of 4th edition.

dangan ronpa! daegan's near-misanthropic nature i feel like would fit right in as one of the students, and knowing how wacky the games are, i wouldn't be surprised if her powers could get justified in one way or another.

Riley's giving me vibes of a western-based series for sure! Maybe Steven Universe or Invander Zim? I'm more leaning on the latter one because of the overal color scheme have slight neon vibes like the actual show, even though her non-humanoid form also does fit SU

She looks like she'd fit in well in the Jojo series- and her powers and stories seem like they'd fit in well there!

It may look weird, but I really thought that he would be a good Wreck-it Ralph character because of the sugary design, just like Vanellope's game main theme. Ignore this thing lmao

I would say Adventure Time. Mostly because the design is pretty unique, a design that would work fine on Adventure's Time universe. _{And the backstory maybe could fit on somewhere of the main story ree}

Design wise, she reminds me of a character who would be in cuphead! Her aesthetic fits the early cartoony aesthetic that the game has.  The way she is drawn makes me think of invader zim, too.. Idk how accurate htis is since im not a big fan of either but asdgfhjk

im getting panty and stocking vibes, mostly due to the art style and even though he isn’t a demon, he vaguely reminds me of those demon sisters from the show??

(Oh what a cutie!)
Hmm...
I don't really know much about it myself, but the fact that he's a zombie combined with his bright colors, cute design, as well as the proportions, he reminds me of a character I could imagine seeing in the Monster High show and toy-line.
Like I think he'd look pretty good in doll form as well. He'd fit right in!

I think, His Majesty, this really handsome, but odd-looking person, can be a boss from oldschool JRPG like Lunar or FF5. Or, maybe, he could fit in the best japanese roguelike: Elona+. 

Mark somewhat gives me Gravity Falls vibes, probably due to the outfits he's wearing in the images in his gallery. I'm assuming that he would be some kind of a supporting character if he had a role in the series itself. Plus, the room in one of his images looks like something from Gravity Falls as well!
