Erol Otus' aliens make another appearance in the Star Control I game manual--this piece is called "Fighter Pilot Considering its Options." The names on some of these pieces make me wonder if Otus delivered a number of untitled pieces and the dude laying out the book came up with the captions.
Of course, the picture doesn't map to any of the alien races featured in the game, so that might be why "it" (not he or she!) has been relegated to a laserfire magnet in a nondescript starfighter. Either way, he's freaky cool lookin'!
