 The player is given a starship , and the main mission is to fight an alien race called the Distilled Evil and their slaves , the Sporg . The Sporg are mining ships controlled by the Distilled Evil , tasked with powering the jumpgate , a portal through which the Sinistar ( a bio @-@ mechanical monster dedicated to destroying the player ) appears . The jumpgate is stationed at the center of the level , and the Sporg power it with energy crystals collected from the asteroids that appear sparsely along the sector .
