Charlie Weasley is a natural choice. Since he works with dragons in Romania, he could be the center of a story where he discovers a new dragon breed and has to bring it back to Hogwarts for some reason, like it's the key to defeating a new threat to the wizarding world. He would have all sorts of adventures along the way, trying to keep the dragon calm and safe during the journey.
Hermione Granger is also a popular character. In some fanfictions, she uses her vast knowledge to study dragons in a way that no one has before. She could be researching dragon magic or trying to find a way to communicate with them on a deeper level.
In many Harry Potter dragon duelist fanfictions, Hagrid is a beloved character. His love for all magical creatures, especially dragons, could lead to some interesting storylines where he either helps train dragon duelists or gets involved in some way. Luna Lovegood is another character that often shows up. Her unique perspective and magical abilities could make her an unexpected but powerful dragon duelist. And then there's Sirius Black, whose wild and rebellious nature could be well - suited to the high - stakes and dangerous world of dragon dueling.
Obviously, Harry Potter is one of the main characters. Since it's a fanfiction about him as a dragon or related to dragons, he would be central. And I think Hagrid would also be an important character as he has a great love for magical creatures, especially dragons. He could be the one to help Harry understand his new relationship with dragons.
Often, the main characters can include the well - known Harry Potter characters like Harry himself. He might get involved with dragons in some way, perhaps during one of his adventures outside of Hogwarts. Another common main character could be a new, original character created specifically for the fanfiction. This character could be a dragon trainer or a researcher of magical creatures, with a special interest in dragons.
Hermione Granger is often a popular choice. Her intelligence and thirst for knowledge can be an interesting addition to the Dragon Age world. She could study the magic there and perhaps help solve some of the problems in Thedas. Another popular character is Alistair from Dragon Age. His noble and somewhat naive nature could create some interesting scenarios when placed in the world of Harry Potter, especially at Hogwarts where he'd have to learn a whole new set of magical rules.
Definitely Goku. His super Saiyan forms and his ability to fight powerful foes would make for some exciting crossovers in the Harry Potter world. He could use his ki blasts instead of spells. Vegeta is also a popular choice. His pride and determination could be an interesting contrast to the more humble characters in Harry Potter. And then there's Dumbledore. He could be seen as a wise mentor in the Dragon Ball Z universe, guiding the Z - fighters with his knowledge of magic and wisdom, much like he does in Hogwarts.
Sometimes, even minor characters from the original series are turned into officers in fanfiction. Like that one wizard who was always in the background at the Ministry of Magic but in fanfiction becomes an important officer involved in a big plot to uncover a conspiracy within the ministry.
Hermione often makes an appearance in these fanfictions. Her intelligence could be put to use in understanding the unique cultures and behaviors of the furry characters. For example, she might be researching a spell to communicate with a group of furry magical beings.
Harry Potter himself is still very popular in fanfiction. Writers often put him in new situations or give him different character developments. Hermione Granger is also a favorite. She's often made even smarter or given new challenges to overcome. Draco Malfoy is another one. Fanfiction writers like to explore his character more deeply, sometimes making him a more sympathetic character or showing his inner struggles.
Well, obviously Fred and George Weasley are the central characters. Their mischievous and fun - loving nature makes them very popular in fanfiction. They are often depicted as heroes in different scenarios, using their pranks and magical skills to get out of tough situations.
Harry Potter himself is often a central character in such fanfiction. He might be the one with the unique summoning abilities or be involved in training others in summoning magic.
