Robinson Sr. by Pier-Giorgio Tomatis The aliens are back. Save yourself ... Robinson Sr. If you thought that the aliens of Blue Paradise were missing, you will have to change your mind. They are back. More deadly than ever. They still want our planet and they don't care about the fate of its inhabitants. Our only luck is to have Peter Cruise among us: the human who is the greatest killer of aliens in the entire Universe. Will it be enough to save us?
