Horvitz Hullabaloo

Horvitz Hullabaloo are the 9th characters featured in Another Unnecessary Tournament, originating from The Grim Adventures of Billy and Mandy and Invader Zim series.

Bio
It's an alien invasion! The loud, short in temper (and stature) Invader Zim aims to take this tournament for the Irken Empire! He's even recruited a human to help him along the way, an idiotic child named Billy. Sharing the voice work of Richard Horvitz, this unlikely pair brings with them sources of death and aliens, alongside a surplus of music from dark and horror-based children's entertainment. When these two work together, prepare for doom; so long as hubris doesn't get in the way of progress. They've certainly got more than a grim chance at winning at least.

Physical Appearance
Both characters appear in Another Unnecessary Tournament as they does in The Grim Adventures of Billy and Mandy and Invader Zim respectively. Billy is a red-haired boy with a big pink nose and beady little black eyes. He wears a white short sleeved t-shirt with a thin horizontal blue stripe and a pair of blue jeans, alongside a brown baseball cap on his head and a pair of white and red sneakers on his feet. Zim is a short, green-skinned alien with ruby-colored eyes, zipper-like teeth, a pair of antennas, and a long, worm-like tongue. He wears a red tunic-like garment with three black stripes and a triangular pink collar and sleeves, as well as black boots, leggings, and gloves.

The outline of Horvitz Hullabaloo's internal component is light green, with the Irken Empire insignia on the bottom right and what appears to be a silhouette of the Grim Reaper.
