Rogue Chip's attack:

RC checked his time coordinates and stun gun. "Strange," he thought, "bringing a stun gun to an assassination. But even though he deserves to die, so this is an execution, I can't bring my self to kill him directly in cold blood. Well time to stun him and leave him to die."

The time machine phased into position just as Tempus finished setting the timer on the bomb and started the one hour count down. RC shot him with a stun bolt that would keep him frozen for 24 hours and phased out of the time stream, satistfied that Tempus would soon be dead by his own hand.

Unfortunately, Superman showed up and disarmed the bomb, seeing it as intended for Lois, who had received a strange phone call for someone named Chip calling her to another location for a scoop.

Thus while trying to save Lois who wasn't in danger he saved the villain instead.

Well these things happen. We'll just have to try again.
