Mechonoid Mechonoids were large spherical robot s originally built by human s to help colonise worlds until they were abandoned and forgotten on Mechanus . The Mechonoids became a force in their own right and Mechanus became their home planet . They were one of the few beings who could prove a match for the Daleks . History . The Mechonoids first encountered the Daleks when they built a space station for refuelling on the route to the planet Oric . The Mechonoids used their suspicion ray on one of the Daleks there , causing it to perceive other Daleks as its enemies and kill them . The Mechonoid Interceptor which held the ray was destroyed by the Daleks , but the Dalek ship was then attacked and melted by two other Mechonoid ships . The Mechonoids then broadcast a message to the Daleks on Skaro , warning them to avoid their territory . The Daleks instead began preparing for war with the Mechonoids . ( COMIC : " Eve of War " ) The Zerovian s , seeking to prevent war from breaking out between the Daleks and the Mechonoids , sent their robot agent , 2K , to accomplish this . The robot manipulated the Daleks into destroying the rogue planet Skardal , which they had set on a collision course with Mechanus , then told the Mechonoids that the Daleks had saved them purposely . The Mechonoids then called off the war , although they still considered the Daleks their enemies . ( COMIC : " Impasse " ) Some Mechonoids were sent by human s to prepare Mechanus for colonisation , but Earth got caught up in interplanetary wars such as the Human - Draconian War , the Second Dalek War and the Third Dalek War which put an end to the Earth Empire ' s expansionist phase ( PROSE : " The Chase " ) and the colonists never arrived .

At some point , a Dalek force attacked the station while searching for " the Abomination " , and the Mechonoid shells were destroyed along with the station . ( COMIC : " The Only Good Dalek " ) Morality . Mechonoids did not seem to be inherently bad or good , as they only turned violent when their home planet was threatened .
