Cores & Hollows

Cores & Hollows are two types of parasites from the cross dimension, the first type cores enter through a victims body and replace all their internals with enhanced systems and the person doesn't even know what has happened to them even when the Core takes over control of their bodies, however to keep itself alive the Core must remove mental energy from other creatures to stay active

Basically the core will stalk its victim and extrude its large long tongue which will bell out and envelope the persons head, then small tendrils will enter through the ears, nose, eyes and mouth and suck mental energies from the victim causing them to lose all boosts and mental exertions and defense stats.

After it is done feeding the Core will just leave their victim where it is, the tongue will detach from the covering of the head and retract, the head coating will then completely cover the entire body of the victim turning them into what is a called a core zombie which will hide and slowly feed off of other persons mental energy and then move to a new location to keep itself alive the coating is always coating the zombies body and is a dull tan color and their face is completely covered as well showing a mouth open in a rictus of horror with the eyes open wide in fear and the head will be cocked to the side as if it has been broken, if an esper is attacked by a core it will however become a new core rather than a core zombie.

Hollows are parasites that enter and eat away the insides of their victims till they look thin and emaciated, the hollow negates this by enveloping and digesting victims until they are completely dissolved and repeat the process.

Cores and hollows are always on the look out for one another because if they combine and become one creature they become extremely dangerous, the hollow will envelope the core and retain all the enhanced body systems that the core created for its puppet and the Hollow has extremely hard to damage skin [basically the creature will have DD10 and crap tons of hit points and be immune to critical hits unless they actually cut off a limb - which is extremely hard]. Only Five Corrollows as they are called exist and are currently stranded on a former Theban Colony world after having devoured and decimated the 100,000 person colony.
