Hubble's original message was mis-heard by an alien who, thinking the Earth was under attack from super-beings, sent the blobs - Adaptoids - to rescue the Earth.The alien contacts the League and challenges them to take on the Adaptoids but, no matter what the Leaguers do, they are defeated and forced to retreat to the satellite where they find that Hawkman has left his post to return to Thanagar.
