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.
Sailor Jupiter might be another good ally for Batman. She's strong and has a no - nonsense attitude. If there was a brute - force - type villain in Gotham that Batman was having trouble with, Sailor Jupiter could step in and use her physical strength. In return, Batman could teach her some of his stealth and strategic skills, which would be useful for her in future battles in her own world.
Well, the Black Ranger might also be a good match. He is a strong leader among the Power Rangers. Batman, being a natural leader himself, could respect the Black Ranger's leadership style. Together, they could lead a combined force of Gotham's vigilantes and the Power Rangers against a powerful enemy, coordinating their teams' efforts and using their combined resources to the fullest.
I think Sam from Danny Phantom would get along well with Black Widow. They both have a no - nonsense attitude and are strong - willed. Sam could teach Black Widow about environmental protection, and Black Widow could train Sam in more hand - to - hand combat skills. Also, Tucker might be an ally to Iron Man. Tucker's love for technology and his skills in that area would make him a great partner for Tony Stark. They could collaborate on creating new gadgets that combine Danny's ghostly technology with Stark's high - tech creations.
I think Sans and Iron Man could be great allies. Sans is intelligent in his own way in Glitchtale, with his knowledge of timelines and shortcuts. Iron Man is a tech genius. They could combine their knowledge to create strategies against common enemies. Iron Man might be intrigued by Sans' magic - like abilities and try to find a scientific explanation for them. Sans, on the other hand, would be impressed by Iron Man's high - tech gadgets.
Ezra and Spider - Man would be likely allies. Ezra's ability to connect with animals through the Force could be useful when combined with Spider - Man's agility in urban environments. They could both use their skills to gather information or carry out stealth missions.
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.
Alfred is always a likely ally. His knowledge and experience can provide valuable support to Batman. Also, Oracle (Barbara Gordon) could be an important ally, using her hacking skills to disrupt any technology Superman might use or to gather information.
Sailor Moon would probably be really curious about Batman. She'd be constantly asking him questions about his gadgets and his mission. Batman, being the brooding type, might be a bit annoyed at first but would soon realize her good heart. He'd start to respect her powers and they'd form an unlikely alliance.
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.
Sailor Moon herself, Usagi, could be involved in a kissing scene with a character from another dimension or a time - traveler. This would introduce an element of the unknown and expand the universe of the fanfiction. Or perhaps Chibi - Usa could grow up and have a romantic moment with a character, which would be an interesting twist in the 'kissing you sailor moon fanfiction'.
Han Solo and Star - Lord would probably be great allies. They both have that roguish charm and are good at getting out of tough situations. They could team up on some space heist or adventure.
