However, some might argue that characters like the Lich King in World of Warcraft are extremely powerful with their control over the undead and powerful ice magic. But if we consider the Naruto characters' potential to grow and adapt, Naruto or Sasuke could potentially match or even surpass the power of the Lich King. It would depend on how the crossover is written and the specific challenges they face in the combined universe.
Sasuke could also be extremely powerful. His sharingan allows him to copy and predict moves, and his rinnegan in later developments gives him access to powerful abilities like teleportation. In the WoW setting, he could use these powers to outwit and overpower his opponents. He's also very skilled in ninjutsu, which could be adapted to the magic - based combat in WoW.
It could be Sargeras from World of Warcraft. His immense power as a titan could be really hard for Naruto characters to deal with. He has the ability to destroy entire worlds and his magical power is off the charts.
Sasuke would also be a great choice. His brooding nature and his thirst for power could lead to some really interesting storylines in WoW. He might be drawn to the darker aspects of the WoW world, like the Undead or the demons. He could also have some epic battles with the WoW villains while trying to find his own path.
One might argue that the Sage of Six Paths from Naruto would be the most powerful. He has the ability to create and shape the world. But in the context of a merged universe with World of Warcraft, the Lich King also has great power. He commands the undead and has powerful necromantic abilities. If they were to face off, the Sage of Six Paths' positive energy - based powers might be at odds with the Lich King's necromancy. It would be a battle of two very different but extremely powerful forces.
Naruto himself would be extremely powerful. His Nine - Tailed Fox chakra gives him an almost limitless source of power. In World of Warcraft, he could use this chakra to perform massive attacks like the Tailed Beast Bomb. His ability to learn new jutsu quickly and his strong willpower would also make him a formidable force against the various threats in the Warcraft universe.
It's really hard to say. Naruto in his strongest form, like when he has the power of all the tailed beasts, is extremely powerful. He has incredible strength, speed, and the ability to use a vast array of jutsu. However, Aang in the Avatar state has access to all four elements and can be a formidable opponent. If we consider the Avatar state's spiritual connection, it could give Aang an edge in a battle of wills.
Sesshomaru could also be a very powerful character in this crossover. He has his own powerful sword, Bakusaiga, and his inhuman strength and speed. He is very experienced in combat against demons. Compared to Naruto's friends like Sakura, Sesshomaru would likely be much more powerful in terms of raw strength and combat ability. But Sakura has her own medical ninjutsu and superhuman strength when she releases her inner power, which could also be useful in different situations.
Sasuke would also be very powerful. His Sharingan gives him enhanced perception and the ability to copy moves. In the SAO world, he could quickly analyze the fighting styles of opponents and come up with counter - strategies. His Chidori and other lightning - based jutsu could be very effective against the digital enemies in SAO.
However, we can't forget about Steve. He has been living in the Minecraft world for a long time. He has in - depth knowledge of how to build the most powerful weapons and structures. He can use his pickaxe with great skill, which could be as effective as a ninjutsu in some cases. Also, his ability to survive in the Minecraft world's harshest conditions gives him an edge over the Naruto characters who are new to this environment.
It could be Naruto in his Sage of Six Paths mode. He has incredible power, with the ability to fly, use various powerful jutsus, and his chakra is off the charts. In a fight against the characters from Toriko, his speed and strength would be very difficult to match.
In a naruto tekken crossover fanfiction, I think Orochimaru could be a very powerful character. He has the ability to use various snake - based jutsu and is a master of deception. He could potentially use his skills to outwit Tekken characters. But on the Tekken side, characters like Heihachi Mishima with his Mishima - style karate and his decades of fighting experience would also be a formidable force. It really depends on the environment and the nature of the encounter.
