Telepathic mind control and shape shifting? Check. Police radio broadcasting voice? Check. Super-antiquing breath? Check. What's next? How about the eerie ability of Superman to feign physical death? Beginning as early as 1940, Superman would occasionally stop the beating of his heart to simulate a death-like state. This unsettling superpower was never really explained in any way until Superman #118 (1958). In "The Death of Superman", we find the Man of Steel captured by an evil impersonator and kept helpless by a kryptonite-tinged glass slipper (don't ask).

Not so fast, Superman Impersonator! Three pages later, a decidedly non-dead Superman crashes the crime syndicate's party and offers an explanation for his "death"...
So "super muscular control" was not only the key to feigning death, but also to its opposing (and equally creepy) bonus power of super-loud heart throb!
