McGregor's unruly behavior and his disrespect towards Khabib. He said things that were completely unacceptable. Khabib, being a proud fighter with strong values, couldn't let those remarks slide. So, he took on McGregor in the fight to set things straight and prove his worth in the MMA world.
In RWBY fanfiction, the Weiss vs Winter fight can be a display of their different combat styles. Weiss is more about grace and precision with her Glyphs, while Winter, being more experienced, has a more refined and perhaps harsher style. Their fight could also explore their complex relationship as sisters.
Yes, there might be. The world of fanfiction is vast, and with the popularity of both Naruto and Kaido from different fictional universes, it's not unlikely that someone has created a crossover fanfiction where Naruto has some sort of connection to Kaido. You can search on popular fanfiction websites to find out.
Jealousy is a common reason. For example, if one wife has a more luxurious lifestyle or gets more attention from others. Another reason could be competition, like competing for a limited resource such as a particular job opportunity in a small community where their husbands work at the same place.
In a battle between Blade and the Twilight vampires, Blade has been trained to fight vampires his whole life. He has his trusty sword and his knowledge of vampire weaknesses. But the Twilight vampires are not your typical vampires. They are more 'civilized' in a way. If it was a group fight, Blade would be at a disadvantage against a large group of Twilight vampires as they could coordinate their attacks using their mind - reading abilities among themselves. However, Blade's tenacity and combat skills should not be underestimated.
It's really hard to say. Aang was a very powerful Airbender and the Avatar. He had the advantage of being able to enter the Avatar State more easily due to his spiritual connection. However, Korra was a very physical and aggressive fighter. She had mastered all four elements and was not afraid to take on tough opponents head - on. In a fight, it could depend on the circumstances, like the location and whether they have any outside help.
In my opinion, Kirito and Asuna could potentially win. Kirito has his dual - wielding skills and Asuna is no slouch either. They have fought against powerful bosses in SAO. Naruto is strong, but he might be caught off - guard by their speed and teamwork. Kirito and Asuna have a lot of experience fighting together and could coordinate their attacks well. If they can quickly close the distance and take Naruto out before he can use his more powerful ninjutsu, they could be victorious.
