Dark samus (Trace) is a being with the abilities of Trace but boosted by Phazon. He looks similar to Dark Samus 3 and 4 from Metroid prime 2 Echoes.
One time when Trace was looking for a planet to capture for his race, he found Phaze. Phaze was the source of all Phazon. He decided to land an capture the planet because of it's high energy readings. Unfortunately for him, he was corrupted and converted into a basic template for Dark Samus.
