At the bottom of the alien hierarchy, we have the lowly Sectoid. With only three health and a plasma pistol, they arent a much of a threat. However, they almost always appear in several groups (usually consisting of three each) and are capable of using minor psychic powers to boost another nearby sectoid. The boost grants the chosen sectoid an extra health point until their next turn but does come with a drawback. Should the sectoid providing boost be killed, this will cause a psychic backlash that instantly kills the other sectoid. As to their name, it was given to them because of the manner in which their insides and organs have all been divided into sections.
