In the Whiz #14, Billy Batson has been captured by Sivana and placed in a rock-walled room with no doors or windows. Billy transforms into Captain Marvel to bust his way out and then Sivana appears - passing straight through the walls like a ghost! Marvel lunges for Sivana only to have him disappear again. Captain Marvel calls upon his great wisdom to figure out what Sivana is doing.
In a matter of moments Captain Marvel has solved the knotty problem and comes walking through a solid rock wall much to the horror of Sivana! Captain Marvel begins chasing Sivana with both of them running through the walls of the underground lair.
Captain Marvel has great powers, but he also has some great abilities as well. Just all the more reason why he is the World's Mightiest Mortal!!!
