Puppeteer. One of the best Impostors roles in the game. Puppeteers can select any player and lock on to them. After a few seconds, a connection will be established, and the Impostor will be able to take control of the connected player for up to 10 seconds.
Seer. This role might potentially be one of the most overpowered in the entire game, since they can literally see a player's faction. Their special skill lets them scan a player and, after a few seconds, see if they're a Spacecrew or an Impostor, or a Neutral faction.
