I just had an idea for a droid character. The droid was reprogrammed multiple times throughout its lifespan, and occasionally the previous "minds" of the droid take charge. Could provide an interesting Threat/Despair hole (a mind inconvenient at the time takes over) and ditto for Advantage/Triumph (opposite). The real issue, I find, is XP. If this droid has multiple minds, would that warrant extra XP for skills that can only be used if a certain mind was in control, or make multiple character sheets for the character, each with their own Specs and skills etc.

Opinions?

I might give them a bit of extra xp at creation for purchasing some "hidden" skills. After creation though, I'd just suggest that any xp gained gets spent on whichever personality was active the most for that session. That might lead to the droid being a little undervalued compared to the rest of the group, since some of his advancements wouldn't be usable all the time.

It might be best to run different character sheets, but that's a lot of record keeping. Easiest would simply be to mark a skill or talent with the name of the personality (plus "All" for common skills).

Reminds me of "Runt," one of the characters in the X-Wing series (Wraith squadron specifically I believe).

^ Agreed. I think for my own sanity I would have his "main" personality be what you print out, then write in whatever else for his other personalities. Maybe they each have a different obligation, or maybe there's a special trigger that switches between each of them. I think there's lots of possibilities to make this a really cool thing.

I was also thinking of rules for personality switching. I think my original idea would fit, but maybe a Force die in certain situations

A Force Die could work. Or if he took a certain amount of strain or wounds. Maybe on certain rolls if you roll so many advantage or threat. Be creative.

Give the other PC's a chance to write different parts of the back story, perhaps give each 5 obligation to explain. Then don't tell the actual player any of the storys, just bring them out during play

I actually had a similar idea, with an HK forcibly reprogrammed by the Alliance to be a medical droid. My explanation was that he retained all his assassin-oriented programming, but he couldn't harm a sentient species. His character sheet would have reflected both sets of skills, with him having ready access, though he couldn't use combat skills against living beings.

If you want the personalities to be unaware of each other, and you don't mind the player having so many sheets, I would probably do one sheet for each personality, but limit the personalities to two or three at the most. They could each have an individual Obligation, but there should probably also be an Obligation related to the physical body (such as Criminal or Bounty) that remains a constant threat. Further, the personal Obligations should all have the same value so when that player's Obligation pings, it's not dependent on which personality is at the forefront.

Sounds interesting. Could make for a good obligation.

Be careful. I know 2 people with Dissociative Identity Disorder (and a 3rd with Borderline Personality Disorder), and they are very sensitive about the subject, especially as it is portrayed by the media. I think the idea has potential, but you want to make sure your players are okay comfortable with the idea.

I'd say it's a fine line between interesting character idea and overt power gaming. There should be a downside to it and not just a random pool of extra good stuff to use all the time or it's simply OP imo.
