Wenders is a servant to the Darkness working for Sonatine. In one issue Jackie forced him to cooperate in a plan of his to battle the Angelus. He had to throw smoke bombs so that Jackie would be shrouded in Darkness so he could battle the Angelus during the day. For a little incentive to make sure Wenders did it, Jackie dropped a darkling in Wenders pants, if he didn't work with Jackie his penis would be bitten off. In the end Wenders did what he had to, but tried to escape soon after. So Jackie made the Darkling bite - which made Wenders into a eunuch.
Even though this happened, Wenders continued to serve Jackie in any way he could, he even offered him a solution to Jackie's no-sex problem. He offered himself to Jackie so he wouldn't have to worry about having an offspring. Needless to say Jackie tossed him out of the window into a garbage container. Soon there after Wenders was picked up by one of Appolonia's men and tortured him into telling him all he knew about Jackie and in turn he told her everything he knew about the Darkness and the Angelus. When Jackie was captured it was Wenders however who saved him by pulling the curtains closed and shrouding the room in darkness, restoring Jackie to his powers.
Afterwards Sonatine took control of Wenders body but he hasn't made an appearance again.
