One idea could be a crossover where The Punisher teams up with RWBY characters to take on a new, powerful criminal organization in Remnant. He could bring his unique combat skills and no - nonsense attitude to the mix.
An interesting fanfiction could be about a RWBY character taking on the role and ideology of The Punisher. For example, Ruby could be inspired by The Punisher's sense of justice and start using more extreme methods to fight the Grimm, which causes some internal conflict within the team.
The Punisher could be written into a fanfiction where he travels to a different city to take on a crime syndicate that has a connection to his past. Maybe it was the syndicate that was involved in the death of his family in some indirect way. Along the way, he meets local allies who help him understand the different dynamics of the city's underworld. He also has to deal with the local police force, some of whom are corrupt and some who are trying to do the right thing but are in over their heads.
One idea could be exploring Frank Castle's past relationships more in - depth. Maybe a long - lost love from his pre - Punisher days resurfaces, adding an emotional layer to his character. Another could be a story where he teams up with an unexpected ally, like a young hacker who helps him take down a high - tech criminal organization.
In some Punisher Batman fanfiction, the setting might be a Gotham overrun by more extreme and violent criminals. The Punisher could come to Gotham thinking he can clean it up better than Batman. This would lead to a power struggle and also a chance for them to learn from each other's techniques.
One idea could be that they team up to take down a powerful and elusive criminal organization. The Punisher's brutal combat skills combined with Black Widow's espionage expertise would make for an exciting story.
One interesting idea could be a crossover of different timelines within RWBY. For example, characters from the past meet the current ones and have to deal with the differences in their worlds. Another could be a crossover of different teams in unexpected ways, like Team RWBY having to team up with a rival team to face a common enemy that is more powerful than any they've faced before. And sometimes, there are crossovers that involve alternate versions of the characters, where their personalities or abilities are slightly different, which can lead to very unique and engaging storylines.
Another plot could involve a crossover with the Punisher and the X - Men. Frank Castle might find himself in a situation where he has to work with mutants. He could initially be distrustful but then realize they are fighting for a similar cause against a common enemy that is targeting both humans and mutants. For example, a group of anti - mutant and anti - vigilante fanatics.
A crossover with Spider - Man could be cool. Imagine Spider - Man trying to stop the Punisher from killing a bad guy. Spider - Man believes in rehabilitation while the Punisher thinks the only way to stop crime is to eliminate the criminals. This conflict could drive an interesting story.
One idea could be a crossover where a character from RWBY gains the powers of Dishonored's Corvo. They could use the blink ability to quickly dodge attacks in battles against Grimm. Another idea is to have a setting where the world of RWBY is affected by the plague from Dishonored, and the characters have to find a cure while dealing with political unrest.
One idea could be to explore a crossover between RWBY and Darkwatch characters. Maybe Ruby could team up with a Darkwatch hunter to fight a new kind of Grimm that has some vampiric abilities. This would create a really unique dynamic as they combine their different fighting styles and powers.
One idea could be focusing on team strategies for different combat scenarios in RWBY. For example, how Team RWBY might plan to take on a powerful Grimm that has unique abilities. Another could be about the strategic use of Dust in battles, like creating new combinations or ways to deploy it for maximum effect. And a third idea could be exploring the strategic alliances and rivalries between different teams at Beacon Academy.
