Well, it's not a straightforward yes or no. Different Avengers have their unique strengths and weaknesses. Captain Marvel is strong, but there are times when others might outshine her in specific scenarios or battles.
Among the Avengers, many would argue that Scarlet Witch has tremendous power. Her reality-warping abilities can be game-changing. But again, it's not straightforward to determine a single 'strongest' as it varies based on different storylines and scenarios.
The first Avenger in Marvel Comics is Captain America. His origin story and early adventures set the stage for the Avengers team. He embodies the values of justice and bravery that define the Avengers.
There were many explanations for why Black Widow could become an avenger in the Marvel series.
One explanation was that Black Widow was once a member of the Russian Special Forces. She had received a series of training, including stealth, combat, weapon use, and energy collection skills. These skills allowed her to play an important role in battle and also made her a very independent and powerful character.
Another explanation was that Black Widow was a character with special abilities in Marvel Comics. She can absorb the energy of other creatures to gain power and her abilities can be converted between different fields. This allowed her to use energy weapons such as energy guns and energy bars, as well as use energy to enhance her combat strength.
In addition, Black Widow also showed her close relationship with the other Avengers members in the Marvel movies. She sacrificed herself to save Iron Man (Tony Stark), which made her a member of the Avengers. Her experience and combat skills made her an indispensable member and also made her a character who trusted and cooperated with the other members of the Avengers.
Thor is often considered one of the most powerful Avengers. His godly powers, like his hammer Mjolnir and his ability to control lightning, give him a significant edge.
It could be Captain America. He has a strong sense of justice and kindness. So, if he found a dog, he would surely take it under his wing and protect it. Maybe he'd even train the dog to be a mascot for the Avengers.
In some fanfictions, the 7th Avenger could be a time - traveler from the future. This person has come back to prevent a major disaster that the Avengers couldn't handle without their help. They know all about the future events and use this knowledge to guide the team, but also have to be careful not to change the timeline too much.
Percy could also be a big fan of Hulk. Just like Percy has his own 'inner beast' that he sometimes has to control (his demigod powers), Hulk has his own anger issues. Percy might see a bit of himself in Hulk and also be in awe of Hulk's raw strength. He would probably be interested in seeing if there's a way to help Hulk better control his rage, using his own experiences of self - control.
