The ringleader of the nightmare world that he trapped Aqua in, believing she was completely weak after fighting in the Dark World for so long. He was waiting for her in a giant circus tent as a figment of all her doubts, which transformed into a nightmare, so he could confuse into vulnerability. Unlike others of his kind, he is very intelligent and can speak like a human.

-Stomp Parade: Kingabocky stomps around 12 times, each one leaving a shockwave.
