Back in history, the Yorps were slaves to the Gargs, but then the United States launched the Viking Spacecraft which landed on Mars, crushing and killing the hated Garg despot. The Yorps were then free from the tyrannical rule of the Gargs.
Commander Keen's arch-nemesis. Mortimer is usually behind all the schemes to destroy the universe or take things over. He has been known by some species as the the Gannalech or Grand Intellect.

Meep Creature
A green alien that strolls along singing, and in some way expelling slow-moving sound waves. The singing is so bad that the sound waves will kill you! One shot will kill it.
Found in: Keen 3
Melon Lips Creature
These annoying creatures stay in an inconvenient stationary spot, spitting watermelon seeds at you. The seeds and watermelon are deadly to the touch! Flower powers don't affect this enemy.
These stationary platforms keep vanishing and reappearing like magic. Keen can only stand on them when they are visible (if he is not looking upwards).
