He features a vintage 1970s CRT television set for a head, a bowler hat with rabbit-ear antennae, SMPTE color-bar teeth, and puzzle-patterned clothes. Left lost and burdened by his past crimes as public enemy number one in the Mushroom Kingdom, he is offered a fresh start by a mysterious corporation. He teams up with Mr. WPNZ and a new cast of characters.

A bulky, humanoid cyborg-shark assassin with a mix of mechanical parts and sharp, jagged teeth. Equipped with jet-blaster feet, turret-like goggles, and a detachable left hand that transforms into various weapons like guns and chainsaws. He starts out as an imprisoned criminal partner and reluctant ally to Mr. Puzzles. After surviving a universe-destroying rift together, the two find themselves in a strange new world.

A small, bipedal, rodent/rabbit-like creature with soft pink and white fur, four large ears, sharp teeth, and pink-rimmed glasses. She wears a black trench coat with cardboard shoulder pads, a skull-buckle belt, black boots, and has a long prehensile tail that functions as a third hand. She is a peppy, nerdy bookworm in her mid-twenties. Despite her enthusiasm, she comes across as adorable.

He is a massive, towering robotic demon built with bronze armor, chains, razor-sharp claws, talon-like feet, and a ripped gray cape covered in spikes, a sword, and arrows. His design draws visual comparisons to General Grievous. He acts like an over-the-top, violent, cruel brute. However, he struggles with an internal split personality—he is torn between an urge for total destruction and a secret desire for love and kindness.

A green, mantis-like robotic being. Wears a torn dark green fedora with a feather, round red glasses, green and black clothing, and spiked crystal leg protectors. Has long, elastic antennae hidden under her fedora. Holds a stylized lime falchion (a short, broad-bladed sword) with small wing-like appendages.
