Parasites can come in a variety of forms but the most common subtypes are:
- Parasitoids: Some parasites deliberately kill their hosts, such as insects that lay eggs within hosts and have them consume from the inside out - the most iconic of these types of parasites are the Xenomorphs and The Thing.
- Symbiotics: A parasite that actually improves the host and while dependent on the host to survive does not weaken or kill the being, in fact it often bonds strongly and the host may even enjoy its company - a classic example is Venom and Carnage.
- False Immortals: Similar to vampires but take youth or life force rather than lifeblood - they will wither and die without it and are thus dependent on it, much like a drug. An example is Lord Voldemort.
