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.
Thor could be the one. Thor loves all living things. If he found a dog, he would probably think it was sent by the gods for a special purpose. He'd take the dog on his adventures across the nine realms, and the dog would become a legend among the Asgardians.
The story could start with the Avenger having a bad day. They are feeling really down. Then they find a stray dog. At first, they're not sure what to do with it. But as they spend more time together, the dog's loyalty and unconditional love start to heal the Avenger's emotional wounds. Meanwhile, they also discover that the dog has a connection to an old enemy, which leads to a new adventure.
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.
Captain America is a likely candidate. He has a strong moral compass and a sense of protectiveness. He would see it as his duty to take care of the baby. His old - fashioned values would make him a great caregiver, like making sure the baby has a proper upbringing even in the middle of all the chaos in the Avenger's world.
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.
One common plot could be the Avenger taking on a protective role over the baby. For example, they might keep the baby safe from villains who are after it for some special power the baby has. Maybe the baby is related to some important figure in the Avenger's world. Another plot could be the Avenger trying to find the baby's family while forming a bond with the baby during the search. They could face many challenges along the way, like dealing with other characters who misunderstand their intentions with the baby.
There have been many suspects over the years. One theory pointed to a person with a connection to the seedy underbelly of Hollywood at that time. This person might have been involved in illegal activities and had a disturbed mind. But without conclusive evidence, it's all speculation. The case is complex as there were many people who could have had motives, including those who knew the victim Elizabeth Short on a personal or professional level.
In this fanfic, Percy might be seen as an outcast at first among the Avengers because he's so different. But as time goes on, they come to respect his abilities. The story could also explore how Percy's presence affects the dynamics within the Avengers. Does he create new rivalries or alliances? And how does he adapt to their high - tech world when he's used to the more ancient and magical world of the Greek gods? Maybe he even tries to introduce some of his own magic into their technology, leading to some interesting and unexpected results.
In the comics, it's often debated, but many consider Thor or Hulk to be among the strongest Avengers.
It's hard to say for sure. Hulk's raw strength and durability make him a strong contender. But Captain Marvel also has incredibly powerful abilities. So, it depends on how you define 'strongest'.
The title of the strongest Avenger in the comics is subjective. Iron Man's genius and advanced tech give him an edge in some scenarios, and Doctor Strange's mastery of magic is no joke either. So, it varies depending on how you look at it.
