A really cool concept could be a story where the universes merge and the Avengers and DC characters have to adapt to a new reality. They might have to deal with new power dynamics and form new alliances or rivalries.
One interesting concept could be the introduction of new, younger heroes in the Next Avengers era. They might have different powers and personalities compared to the original Avengers. For example, they could have powers that are a combination of modern technology and magic, which would create unique storylines.
One interesting concept could be exploring the backstories of the Avengers in a musical way. For example, how Tony Stark became Iron Man could be told through a song about his journey from a playboy billionaire to a selfless hero. Another concept might be the relationships between the Avengers. A musical fanfiction could have a duet between Captain America and Bucky Barnes, showing their deep friendship and the pain of their separation and reunion.
One interesting concept could be the heroes being reincarnated in different time periods. For example, Iron Man could be reincarnated in the future where technology has advanced even more, leading to new and exciting adventures. Another concept might be the reincarnation of villains as well, which could create new power dynamics and rivalries within the Avengers.
One interesting concept is the role reversal in relationships. For example, male characters turned female might interact differently with their now female counterparts. Another is the change in power dynamics. A genderbent Thor as a female might have a different approach to leading and using her powers. Also, the appearance and costume design can be a fascinating aspect, seeing how the traditional male or female Avengers' looks are transformed in this alternate take.
One interesting concept could be an alternate universe where the Avengers have different powers. For example, Iron Man might have the power of telekinesis instead of his high - tech suits. Another concept could be a gender - swapped Avengers, which would bring a fresh perspective to the characters and their relationships. And sometimes, fanfictions explore what would happen if the Avengers had to face a threat from within the team, like a mind - controlled member turning against the others.
In Naruto and Avengers fanfiction, a cool idea is the exchange of cultures. The Avengers from a modern, Western - influenced world could interact with Naruto's feudal - like ninja world. This could lead to some really unique character development, like Iron Man trying to understand the concept of chakra and coming up with some crazy new inventions based on it. Also, the moral compasses of the two groups could be compared and contrasted.
One interesting concept could be the interaction between Hellboy's world of the supernatural and DC's superheroes. For example, seeing how Hellboy would team up with Batman to fight a common enemy from the underworld. Maybe they would share their different combat techniques and detective skills.
One interesting concept is the twisted versions of well - known heroes. For example, a Batman who has completely given in to darkness and uses extreme and unethical methods to 'protect' Gotham. Another is the alternate versions of the Justice League where their powers are corrupted and they become more of a threat than protectors.
One interesting concept could be a crossover battle between Hulk and DC's strongest characters like Superman. Imagine the clash of their superhuman strength and different power sets. It would be a spectacle of epic proportions.
One interesting concept could be a character being reborn with new powers. For example, a normal person reborn as a meta - human with the ability to control electricity. It adds a new layer of excitement to the DC Universe's already rich tapestry of characters and powers.
