Kling

Klingard Bieckle, better known as Kling, is the main protagonist in the non-canon Just a Neighbor sub-series. Kling is a mineshaft gray penguin malino with a yellow beak and feet, dressed in a green checkered vest. He is mostly shown with a derpy face. But when ambushing enemies, he's always shown with a creepy grin. Kling, at first glance, appears as a welcome humble guy, hiding his true intentions from his victims that are either employees of Pretty Blood or those who are associated with people from the company with rouge intentions. As time progresses with their conversations, Kling would later on invite them to his house and assassinate them.
