Malicrocious are malevolent undead entities formed by some vile infusion of a dead body with surges of pure evil and fiends. A malicrocious's body does not contain the soul of its previous owner. It is a new evil spiritual entity formed from the spawn of darkness itself. The Malicrocious looks nothing as it did in life. The tranformation has greatly physically altered it. Its legs and arms are stretched and warped, its body is bigger, it has wide flap-like wings and glowing purple eyes. Most undead kill the living because they miss life and envy them for it. This one simply destroys because it wants to and get a great amount of warped pleasure from it. It attacks undead and constructs just as eagerly as it does living creatures.
