The first type of Expansion is called the Shift. The Shift takes place when an Among Us has an extreme case of the Impostor Syndrome. The infected Trill, after turning red, has a chance to corrupt the entire Among Us turning them into what is called a shapeshifter. Shapeshifters have the ability to create cocoons that turn them into other crewmates. They sometimes leave skins behind after they shift.

The Transport is the second type of Expansion. Our studies have shown that some of crewmates have learned the ability to vent. Our review of one of the Skeld Scrolls shows that the underground mafia actually taught some of the crewmates how to vent . It is thought that these crewmates tried to help the Impostors.

The third type of Expansion is the Guard. We have noted that when an Among Us dies they become a ghost. In other cases, the ghost will get wings and have the ability to guard or protect other crewmates. They, for some reason, have powers to form a temporary bubble around the crewmates. Studies show that these protection bubble can override an Impostor.

The final type of Expansion is called the Watch. The Watch is when the crewmates has the ability to see vitals at all times. The Watch was given to a certain crewmate (according to the Skeld Scrolls) who wanted to protect Among Us. They always know when someone dies and devote themselves to finding the murdered.
