Cursemite

Giving you the SUCC.

Cursemites are fleas that have been mutated by the Nurgle Gellerpox plague, which has greatly increased these insectoid horrors' size and aggressiveness. They are known to fight beside any creature that has also been infected by the Gellerpox plague. They are NOT Daemonic beasts mind you, as they were regular animals that got Chaos'd in the process.

Overview

Once miniscule fleas, Cursemites are created after feeding upon Warp energy. Still drawn to blood, they are able to spring forwards with shocking speed. Once their mouths find an artery, Cursemites can drain a man-sized host of blood in seconds like something out of Tank Girl. As they feast, the parasite will balloon and swell as well as turn crimson. Only after draining every ounce of blood will they move on.

Crunch

On the Kill Team tabletop, Cursemites are the cheapest model in the Nurglite Gellerpox faction. It can reroll failed charges and pile in 6" and has 2 attacks that scores 2 hits on a 6. Spam them for maximums RAGE as your opponents get tarpitted and drown in an ocean of giant mites.

In 9th Edition, they are the only pests without shooting. However, they have a passable melee attack with Rending. In addition, if attacking an enemy that's already lost wounds, you can give either an extra attack or make your attacks Lethal 5+ so you can make even more crits. In either case, they absolutely need protection in order to avoid getting blasted to bits.
