Well, if we consider Harry Potter's growth throughout the series, he becomes extremely powerful. He has the Elder Wand at one point which is said to be the most powerful wand in the wizarding world. But Dr Fate is a being of immense power from a different realm of magic. If the duel is in a neutral setting and both are at their full power, Dr Fate's ability to foresee the future and his vast array of magical abilities would likely give him the upper hand. However, Harry's courage and the loyalty of his friends, which are also forms of power in the 'Harry Potter' world, could potentially tip the scales in his favor if the author wants to write a more complex and unexpected outcome.
In Harry Potter fanfiction, it's really hard to say who would win in a wizard duel. It could be a character like Harry himself, with his unique skills and the power of love on his side. But then there are also powerful dark wizards that could be created in fanfiction, who might have new and terrifying spells.
It could be Ginny. She is very talented and has a fierce determination. Also, she might know some unique spells that Harry isn't expecting. Her time in the D.A. has made her a very capable witch and she could surprise Harry with her agility and spellcasting speed.
It's hard to say. Gandalf has a lot of raw power and experience. He's faced some really tough foes in Middle - earth. But Harry Potter is no slouch either. He's got his own set of powerful spells and the ability to think on his feet. However, I think Gandalf might have the edge. His magic is more of an all - encompassing force, and he's had centuries to master it.
It would be really wild. Harry Potter in the role of Dr Fate would bring a whole new dynamic. Harry's magical skills from the wizarding world combined with Dr Fate's powers and responsibilities. He might use his wand in new ways while wearing Dr Fate's helmet. Maybe he'd use his knowledge of Hogwarts magic to fight enemies in a different, more cosmic way like Dr Fate does.
Well, in fanfiction, it could really go either way. Harry Potter has his powerful magic like the Patronus charm and the Killing Curse. But Thanos is super strong and has the Infinity Stones. If Harry could somehow get his hands on the Time Stone, he might be able to outwit Thanos. However, Thanos' brute strength and combat experience can't be underestimated.
Harry Potter has the power of magic on his side. He can apparate, use defensive spells, and has his friends to back him up. However, the Joker is a master of psychological warfare. He can manipulate people's minds and create chaos. In a fanfiction scenario, if the fight takes place in the wizarding world, Harry might have an advantage as he knows the terrain and the magic system better. But if the Joker manages to get into Harry's head, it could be a different story. Harry might hesitate or make mistakes, which the Joker could use to his advantage. So, it's really a toss - up depending on how the story is written.
In my opinion, Hermione Granger would likely win. Hermione has demonstrated time and time again her ability to think on her feet and use her knowledge in creative ways. She's not just book - smart, but she can adapt magic to different situations very quickly. Lily Potter was no slouch, but we don't have as many examples of her in complex magical battles. Hermione has faced Death Eaters and all sorts of dangerous situations and come out on top, so I think she'd be the victor in a duel against Lily.
In a fanfiction, Harry Potter as the Master of Death would likely win. He has the power to control death itself, which is a very fundamental and powerful ability. Thanos, while extremely powerful with the Infinity Stones, his powers are more about physical might and control over the universe on a more material level. Harry's connection to death gives him an edge that Thanos may not be able to counter.
It's really hard to say. Thor has superhuman strength and can control lightning. But Harry Potter has a whole arsenal of spells. If Harry could manage to disarm Thor quickly with Expelliarmus, he might have a chance. However, Thor's physical power is no joke. One swing of his hammer could cause a lot of damage.
It's really hard to say. Darth Vader has his powerful Force abilities and lightsaber skills. But Harry Potter has magic that can be very versatile. If Harry could quickly cast a powerful spell like Expelliarmus to disarm Vader of his lightsaber, he might have an advantage. However, Vader could use the Force to deflect spells or even choke Harry. In the end, it would probably depend on who got the first good shot in.
