As a matter of fact, yes!

We actually wrote a whole fanfic about some of them, and are in the middle of working on a sequel to it, right now. The presence of ghosts in the games makes a convenient excuse for plurality!

The Phantom and the ghost of Bobby Fulbright are a supernaturally originating system of two. Bobby’s spirit was able to latch onto the Phantom’s body and share space with him due to the Phantom’s training making it easy for another soul and personality to share headspace.

The phantom didn’t originally have a name but eventually starts to go by Robert. They function really well, because Robert is able to help Bobby make more levelheaded decisions, and Bobby helps Robert understand and process his own emotions.

Then there’s the “solar system” as we call it– which is another supernaturally originating system of Apollo Justice and Clay Terran. This is another case where a spirit latched onto a body but in this case Clay was able to do it because of how close he and Apollo were in life. Unfortunately due to Apollo having a full personality/soul, unlike the Phantom, Apollo and Clay have more difficulty functioning smoothly as a system, even though they try to support one another. It is possible that they’re headed for a future integration.

Another minor plural headcanons that we haven’t explored as thoroughly in fic, and may not:

We headcanon that Phoenix Wright is actually a system of three (Feenie, Nick, and Mr. Wright), but for the most part they aren’t aware of being a system, have terrible internal communication and don’t notice when they switch.
