Cosmic Scale Damage: Destroying the Earth

What about supers who inflict damage on a really huge scale? What would it take for a super to literally destroy a planet; in particular, to destroy the Earth? The Earth as a whole is inanimate, and has no complex internal mechanical parts; it can be taken as homogenous. It masses approximately 6,500 quintillion tons ("weighs" isn't quite the right word). Taking the cube root, and multiplying by 8, gives 1.88 billion HP; on a planetary scale, rounding that off to two billion is close enough.

The Earth's crust is roughly 10 miles thick, on the average. Rock has a minimum 8 DR per inch; that makes the Earth's DR about 5,000,000. Anything that can inflict a major wound on the planet, let alone smash it, won't even notice that amount of DR!

A major wound to the planet takes about 286,000,000d; we can round that up to 300 million dice. To inflict that much damage with one blow, a super needs ST three billion. If he's getting it from Super-Effort, he needs to buy ST 55 with the Super-Effort modifier, at a cost of 2,200 points. Of course, he probably wants to be able to survive an equal amount of damage. A Damage Reduction factor of one billion looks about right; that costs another 1,350 points. Building him on 4,000 points leaves another 450 points for incidentals such as Flight and Doesn't Breathe.

If anything, this is alarmingly cheap – not necessarily beyond the point range for a really high-end supers campaign. GM considering such a campaign should make sure to set upper limits on ST, damage, DR, and Damage Reduction well below this level. If a hero needs to shatter a planet, he can resort to one-use powers.
