Well, I think Neville could be an ally. He has grown to be a brave and capable wizard. His knowledge of plants and herbology might come in handy, perhaps there could be some magical plants that can be used against the Chitauri. Also, Luna Lovegood might be there. Her unique perspective and knowledge of some rather strange magical creatures could give them an edge in the fight. And of course, the Weasley twins could be great allies, using their inventive magical pranks to disrupt the Chitauri's plans.
Hermione would be a very likely ally. She's smart and resourceful, and could help Harry figure out the best ways to use magic against the Chitauri. Ron might also be there, with his loyalty and fighting skills. Additionally, some of the more experienced wizards or witches from Hogwarts could potentially join in to help Harry.
In this fanfiction, Iron Man could be one of his allies. Iron Man has the advanced technology and firepower to take on the Chitauri. They could combine their skills, with Spider Man's agility and Iron Man's powerful blasts. Another possible ally could be Captain America. His leadership and combat skills would be valuable in the fight against the Chitauri.
In a fanfic where Harry fights the Chitauri, he might use his magic in unexpected ways. For example, he could use spells like 'Expelliarmus' to disarm the Chitauri weapons. His ability to apparate could also give him an advantage in dodging their attacks. Maybe he would team up with some of the Avengers as well, sharing his magical knowledge with them.
Dumbledore could be an unexpected ally. He might see this as an opportunity for Harry to stand up for himself and gain some closure on his difficult childhood. Also, some of the Hogwarts professors, like McGonagall, could be on Harry's side. They have always cared for Harry's well - being and would not tolerate the Dursleys' abuse. And there could be some new magical characters introduced specifically to help Harry in his legal battle, like a wizard lawyer who has a soft spot for underdog cases.
His friends like Ron and Hermione would surely be his allies. They have always been by his side in the original stories, so it's likely they'll be there in the fanfiction too, helping Harry in his fight.
Ron and Hermione are almost surely his allies. They've always been by his side through thick and thin. Hermione's vast knowledge of magic and Ron's loyalty and courage would be invaluable in a mission to destroy the Ministry.
Well, I haven't actually read this specific fanfiction, but generally speaking, it might involve Harry using his magic skills to combat the Chitauri. Maybe he'd use spells like Expelliarmus to disarm them or Protego to shield himself from their attacks. He could also team up with some of his wizard friends to take on the Chitauri threat.
Maybe some unexpected allies could emerge. For example, a centaur who has witnessed the unjust actions of the court might come forward to help Harry. Or a goblin who has knowledge of the court's financial misdeeds could offer assistance. Harry's reputation for being a hero could attract all sorts of beings who want to see justice served in the court.
His mother, Sally Jackson, could play an important role as an ally. She has a strong will and has always been there for Percy. Also, Tyson, his cyclops half - brother, could be a powerful ally with his strength and loyalty. And don't forget about the Nymphs. Some of the water nymphs might help Percy since he has a connection to water.
Ron would also be there for Harry. His loyalty and friendship mean he'd be by Harry's side, maybe even using his own family's magic - related knowledge to assist. And of course, Dumbledore. He has a vast amount of magical knowledge and wisdom, and he'd probably offer some crucial advice or perform a spell to help Harry.
Hermione would definitely be one of his top allies. With her intelligence and knowledge of the wizarding laws, she could help Harry in making important decisions regarding Ministry policies. Ron would also be there, providing his loyalty and courage in times of trouble.
