Mr. WPNZ (short for Mister Weapons) is a charismatic yet sociopathic, ruthless, and bloodthirsty cyborg assassin. He initially comes across as smooth, charming, and approachable, which helps mask his violent nature. Beneath his charm, he is short-tempered, reckless, and genuinely enjoys inflicting violence and murder. As the ex-husband of Karen Katphish and biological father to Zack, Katie, and Cory, he attempts to "bond" with his children by raising them to be cold-blooded assassins like himself. He views them less as kids and more as living weapons or soldiers. He is intensely fixated on Karen and his children, using extreme tactics (like turning innocent bystanders into live-fire practice targets) to force them into his life. Despite his brutal history, he experiences deep internal conflict, displays emotional flooding over lost family memories, forms a genuine friendship with Mr. Puzzles, and ultimately tries to make amends or sacrifice himself to protect others. Mr. WPNZ is a tall and bulky humanoid cyborg with a shark-like appearance. Stands at roughly 6 feet 8 inches tall with a heavy, muscular cyborg frame. Features silver skin, sharp jagged teeth, thick black eyebrows, and an X-shaped scar on his forehead. Yellow triangular or pointed-oval eyes that can turn red and white when he is enraged or feeling intense emotions. His upper eyelids are dark gray and his lower eyelids are dark blue. Wears a white shirt paired with a grey collared jacket and matching pants. Sports a tie shaped like a knife (or a dagger around his neck), a pair of goggles resembling turrets on his head, and armored shoulder pads and leggings. Features a silver glove with a spiked thick wristband that can transform into various weapons (guns, chainsaws, flamethrowers) and rocket-powered feet.
