@ OP
I'd prefer a tier 8 diplomacy upgrade for the novalith. It would be labelled "final solution". It would be a warhead that is shot at the star, causing it to go supernova, and destroying all planets around said star.
This would then leave plenty of little asteroids for the space ponies to munch on to breed into swarms of space ponies.
Once swarms of space ponies are filling the ex-solar system, space pony predators would start to appear.
Sins would be renamed Sins of a Pony Empire.
The wrathful pink ponies would have psychic powers capable of increasing their ability to pull other ponies tails from a distance.
The Yellow fat ponies would wallow around for a while and breed quickly. They would use gang tactics to smudge pony eye makup.
The black ponies would be fast and strong, and they are running from an unseen enemy, the predator of the predators of the space ponies.
Who will prevail?
