You can make the characters more interesting by exploring their backstories in relation to Todoroki's birthday. Maybe a character had a similar experience on their own birthday that makes them connect with Todoroki on a deeper level. Also, show different sides of the characters. For instance, Uraraka could be the one who comes up with the most creative birthday gift idea, showing her creativity and thoughtfulness towards Todoroki.
Develop the characters' relationships with Todoroki in the fanfic. For the teachers, like Aizawa, show how he acknowledges Todoroki's growth on his birthday. He could give Todoroki a special piece of advice. For the female characters, like Momo, she could use her intelligence to plan an elaborate birthday for Todoroki. By fleshing out these relationships and the unique things each character does, they become more interesting.
One idea could be that all his friends at UA plan a surprise birthday party for him. They decorate the common room with his favorite colors, blue and red. Another plot could be Todoroki spending his birthday with his family, trying to reconcile with his father on this special day. Maybe he receives a heartfelt gift from his mother that has a deep emotional significance.
You can give them unique party outfits. For example, Naruto could wear a special Hokage - style birthday hat. And for their personalities, show their different sides. Like Shikamaru might be in charge of planning the party but gets really stressed about it, which is different from his usual laid - back self. Also, add some new relationships or interactions. Maybe Sakura and Ino work together to bake a huge cake for Naruto, and they have some friendly banter while doing it.
The plot twists. In a 'bedazzled todoroki fanfic', the author could introduce unexpected elements related to the 'bedazzled' concept.

Also, the relationships between Todoroki and other characters in the context of this bedazzled scenario can be very interesting to explore.
First, create your OC. Decide on their appearance, personality, and quirk. For example, if your OC has a fire - based quirk, think about how that will interact with Todoroki's dual - element quirk. Then, come up with a basic plot like your OC joining U.A. High School and meeting Todoroki there.
You can try searching on websites like Archive of Our Own (AO3). It has a large collection of fanfics, and there's a good chance you'll find some great baby Todoroki fanfics there.
Add some mystery. For example, hide a secret message in the story that Chibiusa has to figure out during her birthday. It could be a riddle left by a mysterious character.
You could focus on the emotions more. Maybe you were really sad in the morning because you thought everyone had forgotten your birthday, but then in the evening, there was an amazing surprise waiting for you. Describe the roller - coaster of emotions throughout the day in detail. Also, use vivid descriptions of the setting, like how the room was decorated for the party or what the weather was like outside. All these things combined can make your birthday story more exciting.
Set the story in a place that is special to the birthday person. If they love the beach, make the story happen on a beach where mermaids come to celebrate their birthday. Have the characters in the story give the birthday person unique and amazing gifts like the ability to breathe underwater for a day. This way, the bedtime story is not only about a birthday but also something that is very close to their heart.
First, you could start with a description of the setting. For example, if it's in a school environment, describe the classrooms, hallways, and the general atmosphere. Then, introduce Todoroki.

Just a simple, 'Todoroki turned the corner and there she was, in a bright - colored crop top that caught his eye immediately.'
Another interesting concept is a Todoroki family fanfic set in an alternate universe. In this universe, the family could be a normal, happy family from the start. There would be no hero - villain drama, and it could show their day - to - day life, like family dinners, outings, and how they deal with normal family issues.
