Description
Two beings encounter each other on Mars. They each assume the other to be hostile and the green one retreats to his spaceship and takes off. The blue one thinks he's won the faceoff, but the green uses his ship's weapons to destroy the blue one's spaceship and then returns home. The way Ditko draws them, they appear as though they could be aliens, but the end of the story reveals them to be an American astronaut and a Russian cosmonaut wearing space suits that prevented them from even recognizing each other as fellow human beings.
