In a team where everyone is a superhero, people will likely wonder who among them is the strongest. For the Avengers, most of the members of the team will surely be a candidate. When you have a god, a kid with spider senses, and a wizard time-keeper, who could be stronger than them? Luckily, it was revealed by Marvel Studios' boss Kevin Feige who the strongest Avenger is after the events of the Avengers: Endgame, it is Wanda Maximoff.
Wanda Maximoff: The Most Powerful Hero
Also known as Scarlet Witch, Wanda has reality-warping chaos magic where she gets to exhibit powers like hex bolts, telekinesis, and flight, in addition to spells she casts. At one point in the MCU, she even controlled the whole Avengers team with their nightmares and deepest fears. When Feige was asked who the strongest Marvel hero is, he said that Wanda can kill Thanos but was unable to complete the task. In the Endgame, when Thanos got a face to face with her, Wanda could have killed the Mad Titan easily had Thanos not commanded to rain fair just to get Wanda off of him. She brought one of the strongest villains in the MCU to desperation with fear for his life.
Wanda Maximoff as the strongest Avenger makes sense given the comic events.
Following the timeline of the comics of Scarlet Witch, she could easily be the most powerful Avenger there is as she is one of the most powerful characters in the comics having numerous villains beaten out. Her character in the comics was initially considered to be the daughter of Magneto but was, however, retconned. That being said, her lineage gives her an inch ahead of the other heroes. Both in the MCU and the comics, her powers are just ever-expanding.
Wanda Maximoff and Her MCU future
Scarlet Witch is expected to step up her game and be one of the key members of the new Avengers team now that most of the original team members are gone. Wanda also has the potential to be one of the de facto leaders alongside Black Panther, Captain Marvel, and The Falcon for the new set of Earth's mightiest heroes.
Wanda Maximoff is set to return to the MCU with her very own mini-series, WandaVision. Scarlet Witch is also expected to appear in Doctor Strange in the Multiverse of Madness as the MCU shifts into the multiverse and time-traveling.
