Donald Morden

General Donald Morden is the Leader of the Rebel Army. He is the main antagonist in the Metal Slug Series almost every time except in Metal Slug 4 (where only his cyborg clones appear) and 5 (where the Ptolemaic Army is the main antagonist).

In When the Cold Breeze Blows Away, he is the Supreme Commander of the Coalition of the Red Star Joint Military despite of his being led the Rebel Army.
