the Spikes

Planet Hulk 101 pg 18...

spikes are protoplasmic parasites that eat and take over an organisms body, turning them into zombies and forced to become part of a collective, controlled by the larger and least known Elder Spikes.

I had the notion that they control communicate with these zombies by actually swimming and being one with their goo. these giant tendrils or veins spreading accross the infestation also allows them to travel faster. And when summoned they ooze out and all their tech fall in to place.

they are surrounded by spikes(thus the name) and can shift their density, and are living weapons themselves
