Alright. Here's one, it's even related to DC (kind of):
Katio Kid is having an issue. On top of an abandoned building, he is having a showdown with a robot Kid who is trying to take over the world, starting with killing the real Katio Kid. Both are armed with a gun that shoots cards. However, the robot has several addiontal weapons, including missiles that shoot out of his stomach, etc.
The robot shoots Katio Kid in the arm, making it impossibe for Kid to flee. Kid's gun is completely empty of cards. The robot says that since he is a clone of Kid, he can predict Kid's every move and beat him to it 4 seconds before Kid can. That is to say, that if Kid tried to throw the gun at the robot, the robot would do it 4 seconds before Kid.
In the end, Kid must destroy the robot. He is void of other weapons. So how does he do it?
