Definitely Superboy from Young Justice and Black Lightning from the Outsiders. Superboy has his super - strength and Kryptonian - like abilities, while Black Lightning has his electrical powers. Their different personalities, with Superboy being more brash and Black Lightning more experienced and level - headed, could lead to some great character - development moments and interesting interactions.
Artemis from Young Justice and Katana from the Outsiders would be an exciting pairing. Artemis is a skilled archer with a complex backstory, and Katana wields a magical sword. They could bond over their combat skills and share stories about their pasts, while also learning from each other in battle situations. Maybe Katana could teach Artemis some sword - fighting skills to complement her archery.
Forge from the Outsiders and Beast Boy from Young Justice would be really interesting. Forge is a tech - genius, and Beast Boy has his shape - shifting abilities. They could come up with some really cool inventions together, like gadgets that enhance Beast Boy's shape - shifting or help him in combat in new ways. And their personalities, with Forge being more serious about his work and Beast Boy being more laid - back and fun - loving, would create a great dynamic.
Definitely Superboy and Captain America. Superboy with his super strength and sometimes - confused sense of self could learn a lot from Captain America's strong moral compass and leadership. Another interesting pairing would be Robin and Black Widow. Robin's detective skills combined with Black Widow's espionage expertise could make for some really cool stealth and information - gathering missions.
One idea could be that the Outsiders are called in to help the Young Justice team when a new, powerful and mysterious villain emerges. This villain has a unique power that neither team has faced before, forcing them to combine their skills and resources.
I think Thor and Superman would be a very interesting pairing. Thor is a god with his hammer and lightning powers, while Superman is an alien with super strength, flight, and heat vision. They could have some great battles testing their strength and then team up to take on a powerful foe like Doomsday or Ultron. Their different personalities, Thor's more brash and Superman's more moral, would also create an interesting dynamic.
Definitely Flash and Yoruichi Shihoin. Flash is known for his super - speed, and Yoruichi is incredibly fast in her cat form and as a Soul Reaper. They could have a friendly race at first, but then realize they need to work together when a villain who can also move at high speeds appears. Their combined speed could be used to outmaneuver the enemy and save the day.
One of the most interesting pairings would be Black Widow and Catwoman. They are both skilled in stealth and combat. Black Widow's training as a spy and Catwoman's thieving skills could lead to some really cool heist - like scenarios within the crossover story. And then there's Hawkeye and Green Arrow. They are both expert archers and sharpshooters. It would be great to see them compare their skills and work together in a battle situation.
Definitely Superman and Master Chief. Superman has all his superpowers like super strength, flight, and heat vision, while Master Chief is a highly trained super - soldier. They could have an interesting dynamic, with Superman respecting Chief's combat skills and Chief being in awe of Superman's powers. They could work together to take on powerful enemies, like Darkseid if he somehow got involved in the Halo - Justice League crossover.
Batman and Iron Man would be a fascinating pairing. Both are brilliant inventors and strategists. They could compare their high - tech gadgets and suit designs. Batman's detective skills paired with Iron Man's scientific knowledge could make them a formidable duo in solving the mystery of some cross - universe threat. They might also argue about who has the better tech, which would be quite entertaining.
A great plot for Young Justice Outsiders fanfiction could involve a crossover with another DC team or universe. Maybe the Outsiders accidentally end up in an alternate dimension where they have to team up with unlikely allies to get back home. This would introduce new dynamics and challenges for the characters.
I think Danny and Batman would be a really interesting pairing. Batman is all about strategy and detective work, and Danny with his ghost powers could provide a different kind of assistance. Danny might be able to use his intangibility to access places Batman couldn't, and Batman could help Danny with his combat skills and planning.
Wonder Woman and Princess Leia would be an amazing pairing. Both are strong female leaders. Wonder Woman has her Amazonian combat skills and her lasso of truth. Princess Leia is a fearless rebel leader. They could share their experiences in leading their respective groups, and also team up in combat. Leia could show Wonder Woman how to use blasters effectively, and Wonder Woman could teach Leia some ancient combat techniques.
