nemesis prime

Nemesis Prime is an antagonist character from the Transformers series and essentially a dark counterpart to Optimus Prime. While he is usually a Decepticon, there are takes on the character with different origins, such as in Armada where he is a being related to Unicron and in The Last Knight where the name is used for Optimus Prime's Quintessa-induced dark persona.

His Japanese name is Black Convoy. Car Robots presents an unusual case of the character, where his name is Black Convoy in the original Japanese version, but it was changed to Scourge instead of Nemesis Prime in the English dub - despite Scourge typically being a completely unrelated character in English releases.
