The ordinary LEGO block is the most dangerous weapon on Earth--especially against parents. Even Superman can succumb to its brutality. Here, Batman uses his superior intellect to devise the ultimate means of taking down his rival: the kryptonite LEGO block.
Hmm, taken out of context, at first it looks like Batman's glove, but the person in the window is One Punch Man? The artist has very odd pacing/placement of random characters in the window frame on other comics in the same vein. Anyway, Superman should just remember to close the window at night.
