He might have enhanced magical abilities. Since he has infinite time to practice and learn, his spells could be more powerful. Maybe he'd develop new forms of magic that normal wizards haven't thought of. Also, his immortality itself could be considered a power. He could endure any kind of physical or magical attack without dying, which gives him an edge in battles.
Harry would likely have the power to think analytically like Banner. In addition to his existing magical powers, he could use this scientific way of thinking to enhance his magic. Maybe he could create new spells based on scientific principles. And he might have some form of self - control over his emotions like Banner, which could translate into better control over his magic in high - stress situations.
He might have enhanced control over the Hogwarts wards. Since he is the heir, he could be able to manipulate the protective spells around the school more easily than others.
He could have enhanced physical abilities like Black Widow. So, he'd be super agile, able to jump from high places and land safely, and have great reflexes. Also, he might be a master of disguise, which would be really useful in the wizarding world. He could blend in with different magical creatures or people to gather information.
Well, his immortality could change the story in many ways. For example, he might be more reckless in dangerous situations because he can't die. He could also become a sort of mentor figure over time, having seen so much and having all the time in the world to gain knowledge. His immortality might also bring out the envy or fear of other characters, leading to new conflicts.
In this fanfiction, Harry could gain the power of enhanced perception. This would allow him to see things that normal humans or even wizards can't, such as the flow of spiritual energy. He might also gain the power to transform into a more powerful form, like a Shinigami's Bankai. His existing magical powers could potentially merge with his new Shinigami powers, creating something entirely unique. For instance, he could use his Patronus charm in a new way within the Shinigami world, perhaps as a form of spiritual protection.
He would likely have Wolverine's healing factor. So, if he were injured in a battle, whether it was a wizard duel or a physical fight, he would be able to recover quickly. His wounds would close up much faster than other wizards.
Their powers could combine in a really cool way. Harry's magic could enhance Starfire's energy blasts. For example, he could cast a spell on her hands that would make her energy blasts more powerful or more accurate. On the other hand, Starfire's superhuman strength could help Harry in physical combat situations. If they were surrounded by enemies, Starfire could use her strength to clear a path while Harry used his magic to hold off any attackers from a distance.
Well, one unique element is the combination of two very different magical systems. The magic from Harry Potter's world like spells and potions mixes with the magic of the Originals which is more about blood magic and vampire powers.
Hermione might have the power of enhanced intelligence as a demigod. This could allow her to learn spells and magical theories at an incredibly fast rate. Luna could have the power of seeing through illusions more easily, related to her perceptive nature. Maybe she has a connection to a deity that governs truth or clarity.
Well, it could have enhanced speed and stealth. It could move through the halls of Hogwarts undetected and quickly get to places Harry needs it to be. And its venom could be used in a defensive way. If an enemy got too close, the snake could inject a small amount of venom that would paralyze them for a short time. Another ability could be its excellent climbing skills. It could climb up the walls of Hogwarts to access areas that are hard to reach for others.
