I almost missed it, but the robot is actually shooting at the human-bat with his finger. I had mistaken it for a smear on the book. And is that smoke coming out of the spikes on his belt, or those actual smears?
But yes, this is one of best titles I have seen so far!
Mr Home-Gall’s other titles include the fabulous MYSTERY GOAL-GETTER OF THE ROVERS, the stunning LIGHTNING, THE ONE TON WONDER, and the astonishing THE SECRET CENTRE-HALF. He sure knew how to concoct a title!
