Who could be the possible characters as the 'Guardian of Magic' in 'Harry Potter Guardian of Magic fanfiction'?

Lily Potter could also be a great candidate. Her love for Harry was so strong. As a guardian angel, she could appear to Harry in his dreams or in moments of great danger, using her motherly love as a shield and giving him advice based on her own experiences in the wizarding world.

A potential guardian could be Sirius Black's spirit. Even though he died, his love for Harry could be so strong that it allows his spirit to act as a guardian. He could appear to Harry in times of need, give him advice, and even use his limited spectral powers to protect Harry from minor threats.

It could be his mother, Lily. Her love was already a powerful protection for Harry, so in the fanfiction, it could be her spirit acting as a guardian angel, using her love to shield him from harm in a more direct and continuous way.

One interesting plot could be that the Guardian of Magic has to protect a powerful, ancient spellbook that Voldemort is after. This would involve a lot of sneaking around Hogwarts and dangerous encounters with Death Eaters.

Obviously, the Queen would be one of the main characters. And Harry Potter himself would probably be in it too, since it's a Harry Potter fanfiction.

Hermione could be a great magical guardian in fanfiction. She's smart and resourceful. With her vast knowledge of magic, she could protect Harry in many ways, like using her spell - casting skills to fend off dark wizards.

Obviously, Harry Potter is the main character. He is the one taking on the role of the guardian. Hermione and Ron usually play important supporting roles as well. They help Harry in his mission to protect Hogwarts with their knowledge and skills.

The 'Midnight Guardian' might be a reincarnation of an ancient wizard. In some fanfictions, old magic and past heroes can be brought back in new forms. So this 'Midnight Guardian' could be a hero from the past, reborn to protect the present - day wizarding world, especially at midnight when threats lurk in the shadows. They could have unique powers and knowledge that are crucial for the safety of the magical realm.

Harry Potter himself is often a central and popular character. His inquisitive nature and courage make him a natural fit to interact with the new elements from the Stargate universe. Hermione is also popular as she would be eager to study the new technology and alien cultures brought in by the Stargate crossover. She could be the one to figure out how to combine magic and technology.

Sakura could be a great guardian in a 'naruto guardian fanfic'. She has strong medical skills and combat abilities. She could use her medical ninjutsu to heal Naruto when he is injured in battles and also fight alongside him, protecting him from harm.
