Another possibility is that a group of dark wizards and Sith cultists (who have some connection to Darth Revan's legacy) could team up. They would oppose Harry because they don't want a wizard with the combined power of the wizarding world and Darth Revan's heritage to stop their plans of spreading darkness across both the Star Wars and Harry Potter universes.
It could be a new character who is also somehow related to Darth Revan but has been corrupted by the dark side in a different way. This character might see Harry as a rival for the legacy of Darth Revan and wants to use the power for his own evil purposes. They could try to manipulate Harry into joining them or try to destroy him if he refuses.
Voldemort would most likely still be the main antagonist. Even with Harry being the heir of Darth Revan, Voldemort's goal of ruling the wizarding world remains the same. His dark magic and army of Death Eaters would pose a significant threat to Harry and his friends.
It could be Voldemort. Even though the Darth Nox element is introduced, Voldemort might see Harry's new connection as a threat to his own power. He could try to either use Harry's new powers for his own gain or destroy Harry to prevent him from becoming too powerful with this strange new heritage.
One possible plot could be that the main character, perhaps Harry, discovers he has a connection to Darth Revan through some ancient magic or prophecy. This newfound heritage gives him access to unique powers or knowledge. He might have to face Voldemort with these new abilities while also dealing with the moral and ethical implications of being related to a Sith Lord.
In a 'Harry Potter Heir of Sparda' fanfiction, the main antagonist could be a combination of Voldemort and a corrupted figure from the Sparda lineage. Voldemort is still hell - bent on ruling the wizarding world. The corrupted Sparda figure might be jealous of Harry being the heir and wants to take the powers for themselves. They could form an alliance, with Voldemort providing the wizarding world knowledge and forces, and the corrupted Sparda figure bringing in their own dark powers from their world. This combined force would be a huge obstacle for Harry to overcome.
One possible plot could be that Harry discovers he has a connection to Darth Revan through some ancient magic or a prophecy. He then starts to develop powers similar to the Force, like telekinesis but in a magical way. He might use these new abilities to fight Voldemort and his Death Eaters, taking them by surprise as they've never seen such powers before.
Voldemort could still be the main antagonist. Even though Harry has the blood of Darth Vader, Voldemort's goal of taking over the wizarding world remains the same. Harry would have to use his combined powers from both his wizard and Vader heritage to defeat him.
Maybe a jealous student or a group of students who feel threatened by Harry's new - found status. They could be from pure - blood families who think Harry doesn't deserve to be the heir of so many houses. They might start spreading rumors and causing trouble for Harry at Hogwarts, and eventually, their actions could lead to more dangerous situations as they side with darker forces out of envy.
It could still be Voldemort. Even with Revan's training, Voldemort's power and his army of Death Eaters would pose a significant threat. Harry would have to use his newly acquired skills from Revan to finally defeat Voldemort once and for all.
Yes, there might be such a fanfic. It could be about a wild crossover where the magical world of Harry Potter intersects with the Star Wars universe of Darth Revan. Maybe Harry discovers some ancient Sith magic similar to what Darth Revan used, or perhaps Darth Revan's spirit somehow ends up in the Hogwarts castle and starts influencing the students. It's a really interesting concept that combines two very different yet popular fictional universes.
Well, it could be about a world where the magic of Harry Potter's universe somehow intersects with the dark side elements from Darth Nox. Maybe Harry discovers he has a connection to Darth Nox's power or legacy, leading to a struggle between the light magic he's known and this new, darker influence. He might have to face new enemies or make difficult choices regarding this newfound heritage.
In the fanfiction, Darth Revan's training of Harry Potter would be a blend of two different training regimens. Revan would begin with mental training. He would teach Harry to clear his mind, much like a Jedi does, but with a Sith - like focus. This would help Harry control his magic more precisely. Next, he would focus on Harry's combat skills. He would show Harry how to use his wand more like a weapon, not just a tool for casting spells. For instance, using it to block physical attacks as well as magical ones. He would also introduce Harry to the concept of using the environment in combat, like using objects around him to enhance his spells or create distractions. And he would constantly push Harry to his limits, believing that only through extreme challenges can one truly grow in power.
