First meeting of Daleks and Mechanoids

The first meeting of Daleks and Mechanoids was the opening conflict of the Mechon Wars.

According to another account, the "first skirmish" between the two races was in the Mechonoid Incident. (PROSE: The History of the Daleks)

The Interceptor
Space Station M2 reported that a Mechonoid ship was heading for Skaro, averting a planned Dalek invasion of Oric. (PROSE: Help Plea from Planet) Although the ship proved to not be any form of direct assistance to Oric, the Mechonoids began hostilities with the Daleks when they started targeting them with the suspicion ray. This bought the inhabitants of Oric more time, as the Daleks chose to focus on retaliation and preparing for an impending war rather than exploring their planet for its minerals. (COMIC: Eve of War)

On 1 January 2066, TV 21 reported that "the Universe" was waiting to see if the Daleks and the Mechonoids were going to clash in a galactic war after the species from Skaro came up against an enemy equally as clever, ruthless, and mechanical for the first time in their history. The Dalek War Control Room was pictured alongside the article just as an order was given to destroy a Mechonoid spaceship. (PROSE: Daleks Hit Back!) The ship was successfully destroyed, but so was the Dalek flying saucer with the Red Dalek Leader aboard. The skirmish ended with the Mechonoids warning the Daleks to stay out of their skies.
