Who would be the most powerful if Sailor Moon characters joined the Avengers in fanfiction?

I think it could be Naruto in his most powerful form, like when he has all the tailed beasts' chakra and is in his ultimate Sage Mode. His attacks are extremely destructive and he has a lot of combat experience. However, Sailor Saturn is also a very powerful character in the Sailor Moon universe. She has the power of destruction which is on a large scale. If they were to fight, it would be interesting to see how Naruto's positive energy and fighting skills would fare against Sailor Saturn's more passive yet extremely powerful destruction abilities. But overall, Naruto's versatility and his growth potential might make him the most powerful in a crossover scenario.

It could be Sailor Moon herself. Her powerful magic and ability to transform could give her an edge. She has the power of the Silver Crystal which is extremely potent. When combined with the powers of a strong Digimon, she would be nearly unbeatable.

Sailor Moon herself, Usagi Tsukino, is extremely popular in fanfiction. After all, she's the main character. Also, Tuxedo Mask is often a central figure as he has a romantic relationship with Sailor Moon.

The most popular characters in Sailor Moon dark fanfiction are often those with the most complex powers or backstories. Sailor Galaxia, for instance, is a character that many writers like to explore in a dark context. Her power - hungry nature and the fact that she has the ability to steal star seeds make her a great candidate for dark fanfiction. Additionally, the four sisters of the Amazon Quartet can be made into really interesting dark characters, as they have unique abilities and a connection to the Dark Moon.

Sailor Mercury and Batman could be likely allies. Sailor Mercury is intelligent and tech - savvy, much like Batman. She could help him with any technological problems he might face in his fight against crime, while he could offer her his combat and detective expertise. For instance, if there was a villain using advanced technology to cause chaos in both their worlds, they could pool their knowledge to stop the bad guy.

In a combined fanfiction universe, it could be Whis from Dragon Ball Super. He is an angel who is extremely powerful and has knowledge far beyond most characters. He could potentially use his knowledge of the multiverse and his own powers to outwit and overpower anyone. Although Sailor Moon has the power of the Silver Crystal and Goku has his Saiyan strength, Whis' ability to manipulate time and space, as well as his overall power level, might make him the most powerful character. However, it also depends on how the author of the fanfiction wants to balance the powers of the two universes.

Prince Demande is quite iconic. He's the leader of the Black Moon Clan in the series and often the main antagonist in fanfictions related to them. His complex character, with his mix of evil intentions and sometimes a hint of a softer side, especially when it comes to Sailor Moon, makes him very interesting. Another iconic character is Wiseman. He's the one pulling the strings behind the Black Moon Clan in many stories. His mysterious nature and powerful magic add an air of danger and intrigue.

In Fairy Tail fanfiction, Natsu is often very popular. His fiery personality and powerful dragon - slayer magic make him a great character for all kinds of stories. Gray is also a favorite, with his cool ice - magic and his rivalry with Natsu. For Sailor Moon, Sailor Moon herself (Usagi) is a common choice. Her journey from a clumsy girl to a powerful guardian is always interesting to explore. Tuxedo Mask is also popular, especially in romantic storylines. In crossover fanfiction, seeing how these popular characters interact is really appealing to readers.

Another great pairing could be Piccolo and Sailor Mercury. Piccolo is the strategic thinker among the Z - fighters, and Sailor Mercury is the brains of the Sailor Scouts. They could work together to analyze the enemy's weaknesses and come up with plans to defeat them. Also, Piccolo's unique abilities like his regeneration and energy blasts combined with Sailor Mercury's water - based attacks and technological skills could make for an interesting combination.

Another possibility is Doctor Strange. His magic is already very powerful. If he were to gain some of the unique abilities from Ben's aliens, like the XLR8's super speed for his spell - casting, it would make him even more formidable. The power balance really depends on how the fanfiction writer chooses to blend the two universes' powers.
