About the Spoilers:
Spoilers are the fiercest alien invaders in the galaxy. They only invade planets who are completely undefended. They "cram" (torture) weaker species and make the invaded planets turn into leftovers. When at least three Spoiler cruisers combine, they turn into battleship. The invader's most powerful cruiser, the mother ship, serves as the ultimate weapon to destroy the inhabitants.
