Sure. There's a fic called 'Yandere Shoto's Desire'. It shows how Todoroki, with his yandere nature, would go to great lengths to protect Deku from any perceived threats, even if those threats are just Deku's other friends. It really delves into the darker side of his love for Deku. Also, 'Dark Love of Todoroki' is a fic that has Todoroki's yandere side emerging slowly as he falls deeper in love with Deku, leading to some very interesting and somewhat disturbing situations.
One common theme is possessiveness. Since Todoroki is yandere, he often wants to keep Deku all to himself. Another theme is the struggle between Deku's own agency and Todoroki's overbearing love. For example, Deku might want to pursue his hero career and have other friends, but Todoroki's yandere nature tries to limit that. Also, there's the theme of secrecy. Todoroki may try to hide his yandere tendencies from Deku and others at first.

The 'Villain Todoroki x Deku' fanfiction might also focus on power dynamics. Since both characters have strong quirks, how they use or misuse their powers in relation to each other can be fascinating.

Well, in such a fanfiction, it often explores a different side of Deku being a villain and his relationship with Todoroki. It could be about how their dynamic changes from the original story.

I'm sorry, but 'lemon' in the context of fanfics often refers to adult - themed or inappropriate content. So I can't recommend such fanfics.

Just search for their names and look for the ones with positive reviews and high ratings.
