Sydney Lechoix used to be a weakling who was pushed around his entire life. He could never fight back because every time he did, he would get beat down. All this weakness made him one step away from doing something bad like causing a buying a gun to make sure no one would mess with him again. Unfortunately, on his way to a gun shop, the DNAftershock occurred and Sydney was transformed into a leech Hybrid. Considering himself a freak now, Sydney snapped and started attacking anyone around him and he found out two things immediately. He found that when he attacked people, his venom caused them to hallucinate and that his hands have become new mouths that he must feed from now.

Para-Psyche is probably the weakest enemy the Hybrids have ever gone up against but during the first time they meet, Para-Psyche gets them to fight on his turf in the sewers and he quickly defeats all of them. He used stealth tactics to bite them all one by one and caused them to hallucinate and be useless for fighting. If not for Komodo, then they all would of been trapped underground to be used as food as they're slowly drained down to mummified corpses.
