Combining the magic systems of Fairy Tail and Warcraft can be quite complex but also very interesting. For starters, the rune - based magic in Warcraft could be incorporated into Fairy Tail's magic. Mages in Fairy Tail could start using runes to enhance their spells or create new ones. The teleportation magic in Fairy Tail could be combined with the portals in Warcraft. This would allow for faster travel between different locations in both universes. Additionally, the transformation magic in Fairy Tail could be influenced by the shapeshifting abilities in Warcraft. For example, a Fairy Tail character who can transform into an animal could learn to take on more Warcraft - specific forms, like a Tauren or a Worgen, and gain their unique abilities.
One way could be through a magical portal or rift that causes the magic from both universes to mix. For example, Natsu's fire magic could be affected by the dark and mysterious magic of the Black Bird world, making his flames have new properties. Maybe they turn purple or have the ability to nullify certain types of magic from the Black Bird world.
The magic in Fairy Tail could be combined with Pokemon elements by having spells that are related to Pokemon types. For instance, a water - mage could use a spell to create a Pokemon - like water creature. Or a lightning - mage could summon an electric - type Pokemon - inspired bolt of energy.
Well, Mario's jumping and acrobatic moves in Smash Bros could be paired with Happy's flying ability from Fairy Tail. Happy could carry Mario to new heights in the battle area, allowing Mario to perform his aerial attacks from greater heights. And Mario's fireball ability could be enhanced with some Fairy Tail fire - based magic for extra damage.
Well, in Narnia, there's the magic of Aslan which is more of a divine and nature - based magic. In Harry Potter, it's more about spells and potions. You could have a situation where a wizard tries to learn the magic of Aslan. For example, Hermione might be intrigued by the magic that brings Narnia to life and tries to study it. She could combine her knowledge of wizardry with the Narnian magic to create new spells.
The magic in Harry Potter is mainly spell - based, while in The Dragon Prince it is more about primal sources. In fanfiction, a character could try to combine the two. For instance, a wizard could use a spell to enhance the power of a primal source connection. They might use the Wingardium Leviosa spell to levitate an object charged with primal magic.
You could create a new type of magic that combines the two. Let's say there is a character in the fanfiction who is half - wizard from Harry Potter and half - something related to Black Butler (maybe has a demon ancestor). This character has a unique magic that is a blend of spell - casting and the ability to make deals with supernatural forces. Their spells might have a different effect because of the demonic influence. For instance, a simple levitation spell could also cause a small amount of fear in those around them because of the dark undertones from the Black Butler magic.
Well, often in such fanfictions, the Rinnegan is used as a sort of bridge between the Naruto and Fairy Tail universes. It might give a character the ability to travel between the two worlds. And when it comes to combat, the Rinnegan user could analyze the magic in Fairy Tail like they analyze chakra in Naruto. They could then use this knowledge to counter magic attacks more effectively. Also, the power of the Rinnegan could be enhanced by Fairy Tail's magic, making the character even more powerful than in the original Naruto series.
The worlds could also be combined through the discovery of ancient prophecies that involve both. There might be a prophecy that foretells the coming together of heroes from two different realms to save all of existence. This would draw the characters from Fairy Tail and the Seven Deadly Sins together. As they search for the meaning of the prophecy and how to fulfill it, they would gradually integrate their two worlds. For instance, they might find that certain locations in each world are linked, and by traveling between these linked places, they can fully explore and combine the two worlds.
The spells in Harry Potter could be combined with the Thu'um of the Dragonborn. For instance, a wizard could cast a spell to enhance the power of the Dragonborn's shout. Or the Dragonborn could use his shouts to disrupt spell - casting of dark wizards.
The magic systems could be combined in terms of magical education. Imagine a school where students from both universes learn. They would study the basics of both magic systems. So, a student would learn about the seven basic magecraft in Fate Stay Night as well as the different types of spells in Harry Potter. This would lead to a new generation of characters who could blend the two magics in creative ways. For example, using the teleportation magic from Fate Stay Night in combination with a Disillusionment Charm from Harry Potter for a stealthy escape.
