In the Spawn graphic novels (such as Creation) there are numbers (eg 9999) what do these mean?

Answer 1

Spawn has vast magical powers. In the issues before issue #50, Spawn had a limited power supply or "9999". Each time Spawn used his energy, the counter would drain. Because of this reason, he relied primarily on his costume's natural abilities in fights. Other than the counter, the only limit was Spawn's imagination. Though he always tried not to expend a lot of magic, he has been shown using it for a variety of effects including resurrecting the dead, firing blasts of necroplasmic energy, teleportation, shapeshifting, and curing the sick.
