That's because I've been training the newest addition to my lineup, my Duskull.
Like Electro when he was just an Elekid, my Duskull is simply a joy to behold. He looks adorable following me around like some evil spectre of death. Of course, raising him has been something of a chore. Since he's still in his basic evolutionary stage, he's pretty weak and susceptible to KO's quite often. Still, I know that all the bumps and scratches will be worth it, and he'll realize his true potential, just like Electro and Moloch have before him.
Anyways, here's a picture I drew of my Duskull, Ryuk, devouring the souls of his enemies.

Welcome to the lineup, little man! Hope you survive the experience!
