Trilobite 4 1

You whip out your nuclear shotgun boomer plasma destruction kaboom big bang cannons and you fucking blitz the trilobite bastard with bullets and shrapnel and enough radiation to sterilise a planet.

And when you stop, the ocean is radiated as hell and you've caused the Permian-Triassic extinction event. And it's still far, far less than that fucking trilobite deserves. You are a merciful god.

It's all in a day's work. But, so long as trilobites remain out there, the work doesn't stop.

And that's okay. At least you have a role in this world.

You keep swimming.
