Mechon 212
From Tardis Wiki, the free Doctor Who reference
Mechon 212 was a Mechanoid stationed on the planet Hesperus where the Mechanoids had been preparing for human colonisation for centuries, and ended up defending it from a Dalek invasion to that end. During the battle, 212 was summoned by Mechon 84 alongside units 179 and 803, using their combined firepower to destroy a single Dalek at the cost of unit 803. (PROSE: War of the Daleks)
