Hero unit with versatile psychic powers.
Weirdboyz are the most psychically attuned of all Orks. They are capable of vomiting blasts of Warp energy that can reduce foes to molten goop in seconds. Weirdboyz unconsciously channel the background mental emissions of nearby greenskins. Even a close-run squig-eating contest between two rowdy Boyz will cause waves of energy to pulse through any Weirdboy that strays near. Unless the Weirdboy finds some way to release this pent-up energy his head will explode, detonating the heads of nearby Orks into the bargain. This can prove highly inconvenient.
