What is this! Parasyte the Maxim, crossed with a few gore based Manga (Berserk and Blood C come to mind) with a large serving of my (honestly, quite messed up and dark) imagination

lemon and 1842 is a portal 2 reference

six legs. armored scales. adaptable. predatory. Almost sounds like Tyranids

So they're aliens?

Crazy good world building here.

As a red tick appeared in another empty square, a shudder of contentment ran through Twilight’s body. She’d never admit it to anypony – her friends especially – but filling out a check list with those seductively straight-lined ticks was a guilty pleasure of hers.

I'm sorry, what?

"talk dirty to me..."

"Checklists, very looong checklists."

"ooh yeah"

““Ponyville will be fine; we’ve stood against Nightmare Moon, Discord, and bunny stampedes after all. Besides, the whole of Equestria needs you to find out where those creatures are filtering in from.”

Stood up against and fired a deus ex machina but didn't defeat said enemy, a god-like internet troll with the child like demeanor of a three-year old, and baby rabbits eating flowers and food ponies where selling that day. Yep, you can totally handle a attack by those where magic does't effect some of them and a vast thirst for blood! Just fling another 'machina at 'em, should be fine. It's not that it is heavily speculated in this time that the 'animals' are coming from the Everfree, the place right next to Ponyville!

Give it up for Twilight Sparkle everybody!

Twilight is the only one who takes great pleasure in checklists.

She needs help. A lot of it actually.

Or Zerg.

Me think Exo-Toa and Phase II and III Darktroopers would be useful.
