Ooooohh!! That's a hard question because now I'm in my loli phase XDD
I used to be more into shotas years ago, so for now for me it would be easier to say my fav lolis XDD
Btw, uhm... I don't know who my fav is but I have some series where I enjoy specific shotas. For example in Pokémon I LOVE Bede, he's an adorable little bitch and I want him getting dominated by Gloria and I want him getting feminized of course XDD
Also Allister is extremely extremely cuuute, also him submissive of course XDD
In South Park I really LOVE Cartman as a character but Butters is EXTREMELY CUTE!!! He needs to be covered with kisses and cuddles!! And in general I enjoy the shotas here, Stan and Kyle can be cute, idem Kenny, I LOVE Tweek x Craig fanarts and Tweek is sooo adorable, I'm just not particularly into Clyde or Tolkien.
Also, this is a guilty pleasure/choice but, I'm gonna admit... I like Timmy Turner XDDD
He's cute, okay? He has those moments where you can see his tragic side, where it's showed how sad he is inside despite him acting like a jerk sometimes (too sad later seasons focused more on the jerkiness) but... Awwwww! Also I love the fact that in canon he crossdressed (that maid dress!!! AAAAHHH!!!) and was treated as a dog XDD
Then, ooooohhh!!! I love Chibitalia and Chibiromano from Hetalia!! My Italian shotas, they are both adorable, I love how Chibitalia was mistaken for a girl until his voice changed while Chibiromano is sooo bratty and tsundere, like his adult version XDDD
Also technically I could cheat and say that I enjoy shota!Heinz (Doofenshmirtz) and shota!Cedric (from Sofia the first) because I love when my fav pathetic men have a shota version, a shota version that deserves to be molested/LEWDED!!! XDDD
Also I enjoy generally shotas like Luca or Finn or Steven Universe...
I'm not specifically into Phineas or Ferb but it's cute when Phineas gets dominated by Isabella and Ferb gets dominated by Vanessa in fanarts XDD
What can I say? I'm VERY into feminine and/or submissive shotas, for me shotas deserve to get force femmed and dominated by girls (either lolis or older girls), sometimes by older men, but it depends.
Probably I have other fav shotas but now I'm mostly thinking about shota-coded characters, like Ernest Greeves from Lady Layton (he's 19 but he looks like a shota) or Cameron from TD (he's 16 but he looks younger; technically I wouldn't mind the Adversity twins too)...
OOOOOOHHH!!! I also love Kouta from Kanokon!!! He's soooo cute!!! And submissive of course considering how Chizuru acts towards him, but he's adorable!! And very underrated...
Uhm...
Probably now I forgot some shotas and I'll regret when I'll submit the answer XDD
