crossover RP

—noun

When you take a character designed for one genre or universe and integrate them into another.

What is crossover RP in online roleplay?

Crossover RP, or crossover roleplay, is the practice of taking a character originally designed for one genre, universe, or setting and integrating them into a different one.

This can involve characters from different books, movies, video games, or any other media crossing over into a world where they normally wouldn’t belong. It just as easily covers an original character stepping into an established fictional universe, or two whole settings sharing one story.

Crossovers generally take one of a few shapes. In the simplest, a single character visits another setting and has to cope with its rules, technology, and culture. In another, players pick a neutral meeting ground, like a tavern or a city between worlds, where characters from many universes can plausibly show up. A third approach fuses two settings into a blended alternate universe that keeps pieces of both.

Crossover RP overlaps heavily with fandom RP, since many crossovers bring together canon characters from different fandoms. It works just as well with original characters, though, and plenty of games mix the two.

The appeal is getting to explore interactions, storylines, and dynamics that aren’t possible inside a single setting. It’s especially common in text-based games and collaborative writing, where mixing universes only takes agreement between the players, not new art, assets, or code.

One thing it’s not: IC/OOC crossover, despite the similar name, is an unrelated concept about mixing in-character and out-of-character knowledge, and it’s generally considered bad practice. Crossover RP is a style of play; IC/OOC crossover is a mistake.

Crossover RP: a brief history

The term “crossover RP” appears to have developed in online text-based roleplaying communities. It likely started when players wanted to bring together characters or elements from different fandoms or fictional worlds, especially as fan communities grew and began to interact more closely online.

Over time, the term became more widely recognized and used to describe these blended roleplay scenarios. Its meaning has broadened as more players experiment with mixing genres and universes in their games.

How it's used today

Players use the term “crossover RP” when they bring together characters or settings from different fictional worlds within the same roleplay. It appears frequently in groups and communities where mixing universes is encouraged for creative storytelling.

Types of games where the term is commonly used include:

PbP, MUSH, Forum RPG, Chat RPG, Social media RPG, RPI, RPMUD.


Crossover RP examples

  • A character from a high fantasy setting like Middle-earth entering the futuristic world of Cyberpunk 2077, adapting to new technology and societal norms.
  • Characters from different superhero universes, such as Marvel and DC, teaming up to face a common threat.
  • Historical figures from different eras and locations meeting in a time-travel scenario to solve a mystery or combat a universal enemy.
  • Video game characters from different genres, like a classic RPG hero and a modern-day shooter protagonist, joining forces in a mixed-genre adventure.

Myths and misconceptions

  1. Crossover RP is only for inexperienced players or those not serious about roleplaying. In reality, crossover roleplay can offer complex and enriching experiences that challenge even veteran roleplayers.
  2. Crossover RP is chaotic and lacks depth. However, when done thoughtfully, it can create rich, multifaceted storylines and character development.
  3. Crossover RP always breaks all canonical rules. Many crossover RPs work within a set of agreed-upon boundaries to ensure consistency and enjoyment for all players.
  4. Crossover RP means you can ignore character personalities or established backstories. Successful crossover roleplay often requires players to thoughtfully adapt their characters while preserving their core traits and motivations.
  5. All crossover RPs focus solely on action and spectacle rather than meaningful stories. Many crossover games delve deeply into character relationships and explore unique themes that aren’t present in the original universes.


Crossover RP FAQs

How do you start a crossover RP?

To start a crossover RP, you typically need agreement from the other players involved. Choose characters from different universes and decide on a setting that accommodates them: one character’s home world, a neutral meeting ground, or a blended alternate universe. Establish ground rules up front, especially for how magic, technology, and power levels from different universes interact, so all characters can coexist in the new setting cohesively.

Can any character be used in a crossover RP?

In theory, yes. In practice, success depends on how well the character can be adapted to the new setting and how creatively players integrate different universe rules and backgrounds. Some adjustments may be necessary, especially for very powerful characters, to maintain balance and ensure enjoyable play for everyone involved.

What are the challenges of crossover RP?

Challenges include maintaining character integrity while adapting to a new world, balancing different universes’ rules, and ensuring all players have equal opportunities for engagement and development. Resolving conflicts that arise from differing world mechanics and character abilities can also be complex, which is why many crossover games agree on shared limits before play starts.

Is crossover RP accepted in all roleplaying communities?

No, not all roleplaying communities accept crossover RP. Some prefer to keep their specific universe or genre cohesive, and many games with a single established setting only allow characters built for that setting. It’s important to respect the rules and preferences of each roleplaying community or platform.

How do I know if the game I’m playing accepts crossover RP?

To find out if the game allows characters from other genres, universes, or fandoms, consult the rules and guidelines (usually listed on the website or in the community Discord server). You can also ask the community or moderators directly in the game’s forums or text chat.

What’s the difference between crossover RP and fandom RP?

They are closely related. Fandom RP is collaborative roleplay set inside a single existing franchise, using its characters, settings, and rules. Crossover RP goes a step further and mixes two or more of those universes in the same story, so it is best seen as a form of fandom roleplay that spans multiple franchises at once.
