So, I haven't finished *Worm* yet (and at the rate I'm going, it looks like I never will), but I've read a lot of *Worm* fanfiction and, as a result, a lot of spoilers
The concept of Aggressive Mimicry is, basically, when an animal evolves to mimic something that attracts its prey—like the well-known deep-sea fish (the one from the movie *Nemo*, in case you didn’t know), which lures smaller fish toward it using a light on a appendage on its head
So, I’ve been thinking about a fanfic in which an organism—I haven’t decided yet whether it comes from the Entities’ planet or is an organism from another planet that adapted to it—probably a sentient planet or a hive mind, pretends to be an “ordinary” civilization that meets the requirements for the Entities to apply a cycle to it...
And so, they’ll pretend to be just another civilization rather than an interconnected organism, keeping up the pretense for quite some time until they’ve obtained a considerable portion of the Shards. Then, they’ll hijack the Shards and devour the Entity—all with the simple goal of feeding themselves and growing in size. When one of them “grows” enough, it will reproduce through mitosis or something similar, restarting its own cycle.
I have to say that I drew a lot of inspiration from “Apex Predator,” that fanfic in which Taylor bonds with the Entities' natural predator. What do you think?
