Who could be Broly's potential friends in a 'Broly Highschool DxD' fanfiction?

In a crossover with One Piece, Luffy could be an ally. Luffy is known for his open - mindedness and ability to befriend almost anyone. He would see Broly's power and might try to get him to join his crew or at least fight alongside him against common enemies. They could have some really fun interactions, like Luffy trying to make Broly laugh or share his love for food with him.

Well, a plot could involve Broly being part of a special program in the Highschool DxD setting. He might be there to learn about controlling his power in a more civilized way. As he tries to fit in, he could befriend some of the main characters from DxD. For example, he could team up with Issei and his friends to compete in some sort of school tournament that has magical and combat elements. This would lead to some epic battles and also some character development for Broly as he learns about friendship and cooperation.

Perhaps a Saiyan female. Since Broly is a Saiyan, it would make sense for him to be paired with someone from his own race. They could bond over their Saiyan heritage and power.

In a crossover with the Naruto universe, Naruto himself could be an ally. Naruto has a way of seeing the good in people, and he might try to reach out to Broly and convince him to use his power for good. His ability to befriend and understand others could be key.

Another strong opponent could be Hit. Hit has the ability to manipulate time with his time - skip technique. This would give him an edge against Broly. Broly's brute strength might not be enough when Hit can literally disappear and reappear at will, striking at Broly's weak points during his time - skips.

He could team up with Luffy. Luffy is always open to new allies, and Broly's power would be a great addition to the Straw Hat crew. They could go on adventures together and face powerful enemies.

Bulma could be another character paired with the reborn Broly. She might be the one to help him understand the modern world if he is reborn in a different time period. She could use her intelligence to create devices that help Broly control his power better or she could just be there to provide some comic relief in the midst of all the intense Saiyan drama.

Goku could be a likely ally. Despite their initial conflicts, Goku has a way of seeing the good in people. He might approach Broly and convince him that they can work together to win the Tournament of Power for their universe. Their combined strength would be a formidable force.

A futa version of Rias could be an interesting main character. She could have all of Rias's charm and leadership skills, but with the added element of her futa nature, which could lead to different power manifestations and relationship developments, especially with Issei.

Broly is a Saiyan with an extraordinary power level. In this fanfiction, he is the main male character. His relationship with Cheelai is the focus. Cheelai is likely a strong - willed and caring character. She may be part of the same group or race as Broly or from a different one. Their interactions form the core of the story. She might be the one who tames Broly's wild nature or at least tries to understand him on a deeper level.
