Physics and Star Wars
To estimate the effects of the second Death Star, Minton looks into its mass. According to estimated data from some students of Lehigh University, the steel mass needed for building one would be around 770 kilograms times the mass cubed in weight. This would give the Death Star of about ten to the power of nineteen kilograms in mass. Using this data, Minton produces equations that lead him to conclude the fragments would hit the moons surface so hard causing craters almost four times the size of the Chicxulub crater in Mexico. This impact would cause a planetary firestorm and vaporize all lifeforms on the moon.
Death Metal (comics)
There he was found by the alternate versions of several mainstream Marvel Universe supervillains, whom he killed, and several alternate versions of several superheroes, whom he tried to kill. However, Death's Head and Death Wreck also arrived in Charnel's universe, and wound up fighting Death Metal along with the heroes. When that universe's Ghost Rider used his mystical "Penance Stare" on Death Metal, it caused him to see his own sins and realize the extent of Charnel's evil. The three cyborg "brothers" then teamed up and defeated Charnel.
