She could fit in by using her unique abilities. If she has some sort of agility or stealth ability, she could be like a new kind of spy for the team, working alongside Black Widow.
In fanfiction, Bella could fit into the Avengers team by being a bridge between the superhuman world and the normal world. She can understand the concerns of ordinary people and communicate them to the Avengers. This would help the team make better decisions when it comes to protecting the whole world, not just fighting super - villains.
Merlin could fit into the Avengers team in fanfiction by being the magical support. His spells could help in various ways like creating barriers to protect the team or disabling enemy weapons with a wave of his hand. He would also bring a different perspective, coming from a more medieval - like background compared to the modern - day Avengers.
In terms of personality, Gohan is kind - hearted and has a strong sense of justice. This would align him well with the values of the Avengers. He would be motivated to protect the Earth just like the other members, and his positive attitude could help boost the team spirit during difficult times.
Percy would fit into the Avengers in fanfiction by bringing his own set of values. He has a strong sense of right and wrong from his demigod experiences. His powers are also unique. He can control water, which is different from the powers of most Avengers. He could use it to navigate in water - filled areas during missions, or even use it to create distractions. And his loyalty to his friends would make him a great team player.
Gohan is a kind - hearted and powerful fighter. He'd probably be the quiet but reliable type in the team. He'd fit in by being someone the others could count on in a fight.
Noble Six would bring a new perspective to the Avengers. With Natasha as a sort of guide in the team, Noble Six could adapt to the group dynamic. They might be a bit more reserved at first, but as they prove their worth on missions, they would earn the respect of the other Avengers. Noble Six could also help Natasha in dealing with some of the more military - oriented threats, using their own experience from their original world. In a way, they could be like a new partner for Natasha within the team, strengthening the Avengers' overall capabilities.
She could fit in as a strategist. Since Loki was known for his cunning, she might inherit that trait and be able to come up with clever battle plans for the Avengers.
Master Chief in an Avengers fanfiction? Oh, that's interesting. He would probably be a bit of an outsider at first. His Spartan training makes him very disciplined and he might not be used to the more individualistic styles of some Avengers. But his loyalty and sense of duty would quickly earn him respect. His MJOLNIR armor gives him enhanced strength and protection, which would be useful against the powerful foes the Avengers face, like Thanos. He could also share his knowledge of advanced weaponry with Tony Stark, leading to some cool tech upgrades in the group.
Batman would fit in by being the ultimate strategist. The Avengers sometimes jump into action without a fully thought - out plan. Batman's meticulous planning would force them to be more organized. He could also provide a more grounded perspective. Many of the Avengers have superpowers and deal with large - scale threats from outer space or magic realms. Batman, coming from the streets of Gotham, would remind them of the importance of protecting the everyday people.
Sakura's strong - willed and determined personality would mesh well with the Avengers. She's not afraid to speak her mind, much like Tony Stark. And her combat abilities, which are different from the typical superpowers in the Avengers universe, would add a new dimension to their fighting strategies. She could teach them things like how to use the environment to their advantage, like she does in the Naruto world.
They could fit in by using their skills. Nico's combat abilities and Will's support skills would be useful. For instance, Nico could fight villains directly while Will helps from the sidelines.
