Natsu's fire - eating ability would be really unique in the MLP world. He could use his fire magic in a way that might be both fascinating and a bit scary to the ponies. Maybe he could use it to help with things like heating during cold winters in Ponyville. His hot - headed nature might also get him into some funny situations with the more calm and collected ponies.
In the MLP world, Twilight Sparkle is a very powerful magic user. When combined with the Fairy Tail wizards, she could learn new ways to use her magic. For instance, she might learn from Erza how to be more strategic in using magic during battles. And the Fairy Tail members could learn from Twilight about the importance of knowledge and study in magic, as she is always researching and learning new spells.
Well, consider Wendy's healing magic. In a crossover, she could use her magic to heal the wounds caused by alchemical experiments gone wrong or battles in the Fullmetal Alchemist world. In return, the alchemists could teach her about the properties of different herbs and substances that could enhance her healing magic. Gajeel's iron dragon slayer magic could interact with the metal - based alchemy. He could use his magic to shape and manipulate metal in ways that the alchemists find fascinating. And then there's Mirajane's transformation magic. She could transform into forms that are better suited to deal with the alchemical threats in the Fullmetal Alchemist world, while the alchemists could help her understand the physical and chemical changes that occur during her transformations.
Well, think about it. A Pegasus pony can fly, so it could team up with a Flying - type Pokemon like Pidgeot. The pony could carry the Pokemon to higher altitudes for a better vantage point in battle or for scouting. In terms of other abilities, the MLP characters' friendship - based magic might have an impact on the Pokemon. Maybe it could make the Pokemon more loyal or boost their morale, which in turn would make them fight better. For example, Fluttershy's kindness might make a Pokemon less likely to be intimidated by an opponent.
The fire - based abilities of Natsu from Fairy Tail and the ice - based abilities of Hitsugaya from Bleach could create some really cool interactions. Natsu's heat might be able to counteract Hitsugaya's ice in an interesting way, like when they fight together against a powerful foe. Their different combat styles, with Natsu's more brute - force approach and Hitsugaya's more calculated and precise strikes, could also make for an exciting combination.
The Thu'um of the Dragonborn could be seen as a very powerful form of magic in Middle - earth. It might be on par with the most powerful spells of the wizards there. The stealth abilities of characters like Bilbo or Legolas could be enhanced in Skyrim with the use of Skyrim's unique stealth mechanics. And the strength of characters like Aragorn could be combined with the combat skills of the Nords in Skyrim.
Lucy would likely be a bit scared of the Doom Slayer initially. But as she gets to know him, she could start to see his good side. The Doom Slayer might not be very talkative, but his actions would speak volumes. He might save some of the Fairy Tail members from danger, and they would start to trust him. Happy might try to make the Doom Slayer laugh with his silly antics, though it's not likely to be an easy task.
Luffy's stretchy powers could be used in creative ways when combined with Fairy Tail magic. For instance, if he were to stretch around a Fairy Tail mage who was casting a large - scale spell, he could potentially redirect the spell's energy. Natsu's fire magic might be able to make Luffy's rubber burn in a different way than normal, creating new attack possibilities for both of them.
The fem Naruto character's ability to manipulate chakra could blend well with Fairy Tail mages' magic. For example, if she teams up with Lucy, her chakra could enhance the power of Lucy's celestial spirits. Her speed and agility from being a ninja could also be an asset in battles against fast - moving enemies in the Fairy Tail world.
The characters from Dead or Alive, like Kasumi, are known for their agility and precise martial arts moves. If they were to team up with characters from Devil May Cry, they could learn from each other. Kasumi might learn how to use Dante's guns in combination with her kunai. On the other hand, Dante could pick up some of Kasumi's acrobatic flips and use them to enhance his own combat style. It would be a really interesting blend of two very different combat styles.
The Turtles' ninja skills would complement the Power Rangers' martial arts training. For example, Raphael's brute strength and aggressive fighting style could be combined with the Red Ranger's leadership and combat skills. Leonardo's discipline could be shared with the Blue Ranger to improve their strategic thinking. Donatello's intelligence could help the Power Rangers understand and upgrade their technology faster. And Michelangelo's fun - loving nature could lighten the mood during tense battles for the Rangers.
Naruto's Rasengan could be combined with Link's spin attack. Link could use the chakra - infused Rasengan in his sword for a more powerful strike. Also, Naruto's ability to sense chakra could help in detecting hidden treasures or enemies in the Zelda world, which are often masked by magic.
