Dolph

Dolph is a character in Wullfworgenthaler and Dolph & Wulff. He is a blue, psychotic, aggressive, hotheaded hippopotamus who is basically both a Ninja and soldier. He often hangs out with Wulff who is basically the opposite of him (a calm nice guy). Wulff dislikes Dolph's violent attitude which sometimes leads them to an argument. The typical plot is that Wulff tries to interview people and attempts to get on their good side while Dolph breaks in by beating them with his baseball club or just yelling at them.

Despite being an aggressive psychopath, Dolph appears to care about Wulff, and deep down sees him as a friend. He always follows him wherever he's going, and gets jealous whenever he hangs out with someone else.

Some scenes might actually show that Dolph is a good at heart person. He once apologized to Wulff for abusing him, and started being more friendly with him for some time. However, it did not last long before he went back to his violent ways.
