Preta Ghoul's ability, Decay, allows him to melt anything, or any one, he touches. Preta uses this ability by secreting corrosive liquid from the pores throughout his body. Mainly directing his power from his hands, rendering Preta untouchable. While this liquid is dangerous, it can not melt a special type of fabric, worn by Preta. In the anime, Sven discovered this, and used the Apostle's shirt to defeat him.
