Hello ! ❤️✨ thank you so much for the question ! 💕

So of course my absolute fav is Atom from Astro boy/Pluto ! ❤️🖤💚✨The strongest, kindest and sweetest robot ! 🥹❤️

Then some other good boys I find neat :
Steven from Steven universe ⭐️ ( I mean he’s a shota right ? )
( ok maybe I’m cheating her but ) Shota Yuuji Itadori from jjk 🧡 the character is already cute ( and kinda already a bit shota coded hehe ) but his shota version is absolutely adorable 🥰
Arthur from the Disney movie the sword in the stone 🗡️✨ I always find him so nice, he’s a good boy ! ❤️
Tsubaki from the manga shotaoni 💕 I love when a shota strive to be a “top” to his older loved one 😚

There’s plenty others too but that’s what I have in mind for now ☺️

Thank you again for the question ! ✨
