The Pillar Alien is a generic Alien found primarily on Planet X. They have the ability to blend in with the surroundings of the building in Spaceways by folding themselves into the shape of a pillar. However, due to the fact they always spawn in front of the player, all this does is prevent the player from damaging them before they open up, as they take no damage in Pillar form. This ability is not available outside of Story Mode.
