Synthetic

The Synthetic is a night and day role from One Night Ultimate Alien

Ability
The Synthetic will wake up with the other Aliens. The Synthetic wins, and everyone else loses (including the other Aliens) if they are killed. If the Synthetic is not killed, then they cannot win but the other aliens can win.

Strategy

 * For strategies that are about claiming roles from other One Night games, see the Tanner page
 * Outright claiming to be an Alien, while truthful, is not a good idea, as the Village will likely assume you are a Synthetic
 * The exception is claiming Groob or Zerb, since the Village has no reason not to kill you and it is plausible for one of the duo to out themselves
 * Claiming Oracle when:
 * You have a different parity (even/odd) than what the app said for the Oracle is obvious but you might be able to play it off
 * The Oracle is now on an evil roles team OR is now everyone's target is not recommended as it is way too obvious
 * The Oracle now has a center card, meaning that if there aren't a lot of evil roles in game you might be killed
 * Claiming Leader can get Aliens to vote for you and might get a few Village Team votes if you are suspicious but subtle
 * Claiming Psychic and giving false information or viewing a card you couldn't can rouse suspicion
 * Claiming Rascal and claiming to have swapped roles you couldn't have is suspicious, but it is not foolproof
 * Claiming Cow might get you votes if neither of your neighbors can be Aliens but you are tapped
 * Claiming Exposer with no cards revealed isn't subtle but claiming late when you sound desperate might just work, especially if there are few other leads for the Village
 * Claiming Blob might get you killed since the Village has no reason to keep them around
 * Claiming Mortician is a bad idea as the Mortician is not a target for the Village

Role Selection
The Synthetic sways the game less in favor of the Aliens and Villagers as it deceives both sides

The Synthetic is a good role to add if the Aliens might overpower the game to make Aliens doubt if their allies are truly their allies

Trivia

 * According to the rulebook, the reason that the Synthetic Alien wants to die is because he evaluates that his technology is too powerful for the Aliens to wield but still too powerful for the Villagers to wield
