The fanfiction could feature the Celtic gods as well. The goddess Brigid might bless Harry with her skills in healing and crafts. This would not only help him in patching up wounds during battles but also in creating new magical items. Another Celtic god like Lugh could bestow upon Harry his skills in combat and strategy.
Perhaps the Norse gods. Odin could be the one to bless Harry. Odin is known for his knowledge and power. His blessing might give Harry the ability to see the future, which would be extremely useful in his fight against Voldemort. Thor's blessing could also be involved, giving Harry the strength of a god.
It could be the Greek gods. For example, Athena might bless him with wisdom, which would help him in his studies at Hogwarts and in outsmarting his enemies. Zeus could give him the power of lightning, a very powerful offensive ability.
It could be Zeus. He is a powerful god and might see Harry as a worthy candidate for training. He could teach Harry about leadership and power control.
Zeus could be one. He is a powerful god in Greek mythology and might be interested in Harry's story. Another could be Odin from Norse mythology, known for his wisdom. And perhaps Isis from Egyptian mythology, as she has powers related to magic and protection.
The Chaos Gods themselves could be the main antagonists. Their very nature is to create chaos and disorder, which would be directly opposed to the order and stability that Hogwarts and the wizarding world try to maintain.
The four gods in this fanfiction could be created to fit the unique world of Harry Potter. They might be named after something related to the wizarding world, like one could be the God of Magic Wands, another the God of Potions, etc. However, this is just speculation. It really depends on the creativity of the fanfiction writer. They could also be based on the four elements, with each god having control over one element, like fire, water, earth, and air, and these elements play a crucial role in the magic of the Harry Potter universe as described in the fanfiction.
It's hard to say for sure without reading it, but it could be that Harry, Hermione, and Ron still play major roles. They might be interacting with the gods in some way, either seeking their help or being caught in the middle of a conflict involving the gods.
One possible plot could be that Harry Potter gains extraordinary powers due to the gods' blessing. He might be able to defeat Voldemort more easily, perhaps with new spells or abilities that the gods bestow upon him. For example, he could have the power of instant teleportation which would give him an edge in battles and in escaping dangerous situations.
It could be that the gods view Harry as a novelty at first. They might be amused by his wizarding skills. However, as time goes on, they could see his potential and offer him a place among them. But Harry, being loyal to his friends and the wizarding world, would be hesitant. He would have to decide whether to embrace this new life with the gods or stay true to his roots. This internal struggle could be a major part of the fanfiction.
In the 'Harry Potter trained by Gods fanfiction', it's possible that the gods choose Harry because they see his potential to bring balance to the magical world. They train him not only in magic but also in virtues like courage and wisdom. Harry could then use this training to inspire other wizards and witches to fight against evil. He might even introduce new forms of magic governance based on the principles he learned from the gods, which could change the whole structure of the wizarding world.
Well, it could be that the gods see Harry's plight at the Dursleys and decide to take him in. Maybe they give him new powers, train him in godly magic that's different from what he learns at Hogwarts. He could also be sent on quests related to both the wizarding world and the realm of the gods.
Obviously, Harry Potter would be the main character. He would be the one with the new role as the master of the Nordic gods. Hermione and Ron could also be involved. Hermione would be very interested in learning about the Nordic magic and gods, and Ron might be there to provide some comic relief and also be a loyal friend in the new adventures.
