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.
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.
The Ultra Instinct in a fanfiction might also have an impact on the character's growth. It could be a new milestone in their hero journey. Instead of just relying on their existing quirks, they have this new ability to master. This could lead to new relationships and rivalries. Other characters might be in awe or jealous of this new power, which would create more drama and tension within the story.
There's also 'Growth Together'. This fanfic shows how Deku and Todoroki support each other during tough times at UA. They face challenges not only from villains but also from within the school. Their relationship develops as they help each other overcome these obstacles.
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.

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.
You could write their first meeting in a really intense situation. Like during a villain attack at the school. The OC could be trying to save some students and Todoroki comes in to help. Their eyes meet, and there's an instant connection. Or perhaps it's a more ordinary setting like in the cafeteria. The OC accidentally spills their drink on Todoroki and they start off on a bit of a rocky note, but then Todoroki is intrigued by the OC's apology and sincerity.
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.
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.
