One idea could be a story where Fem Todoroki has to overcome her self - doubts while training in a new and challenging environment. Maybe she's sent on a special mission with a group of heroes she doesn't know well, and she has to prove herself.
Another concept is that Todoroki was turned into a vampire by a villain's quirk gone wrong. He then has to find a way to reverse it. He teams up with Midoriya, who is determined to help his friend. They search for a mysterious old hero who might know a cure, all while Todoroki battles his inner vampire nature.
A fanfic could be set during a school festival. Momo is in charge of one of the booths and Todoroki volunteers to help her. They have to deal with various problems like running out of supplies. Momo creates new items with her quirk while Todoroki helps with keeping things cool (literally with his ice) or heating up things when needed. In the process, they share some personal stories and get closer, realizing they have more in common than they thought.
Well, Wattpad could be a place to search for My Hero Academia Depressed Todoroki fanfiction. A lot of fans post their works there. Just type in the relevant keywords and browse through the results. You can also join some My Hero Academia fan groups on social media platforms like Facebook or Reddit. Fans in those groups often share and discuss interesting fanfictions, and they might be able to point you in the right direction for the ones about a depressed Todoroki.
One possible fanfiction could be about Momo and Todoroki teaming up for a special mission. They use their unique quirks in unison to defeat a powerful villain. Momo creates useful items and Todoroki controls the temperature to their advantage.
Well, the plot could start with Todoroki suddenly realizing he has vampiric traits. Maybe he wakes up one day with a craving for blood. He tries to keep it a secret from everyone at the academy, but his performance in hero training starts to be affected. He becomes weaker in the daylight and stronger at night.
Self - discovery is also seen often. The female characters in these fanfics, while interacting with Todoroki, also go through their own journey of self - discovery. They might learn more about their own powers, their place in the hero world, and how they can grow as individuals in relation to Todoroki's presence in their lives.
One common theme is Todoroki's struggle with his family issues. His difficult relationship with his father often plays a big part in his depression in these fanfictions. Another theme is his isolation. He might be shown as feeling alone even among his friends at UA. Self - discovery is also a theme, as he tries to figure out who he is beyond his family's expectations while dealing with his depressed state.
Another possibility is that they could be in a romantic relationship in fanfiction. Momo's calm and intelligent nature might be attracted to Todoroki's strong and stoic personality. They could support each other through the challenges of being heroes - in - training, and their relationship could develop as they share their hopes and fears with each other.
He could get injured in a fight with a stronger opponent. For example, if he faced an enemy with a quirk that could nullify his own ice and fire abilities, he would be at a disadvantage and could easily get hurt.
