The Rutan Host are basicly green blobs who can transform into other creatures. They are at war with the Sontarans and can kill them by giving electric shocks.
In the Minecraft seriesEdit
The Rutans first appeared in Mission to the Sun alongside with the Ice Warriors . It is yet unknown what they're doing there. This is however not the first time the Rutans are seen on the Youtube channel. They also appeared in a remake of a trailer from Horror of Fang Rock.
