Being a variant of Bonkers, Spark Bonkers has a similar build to him. Spark Bonkers is a gorilla-like being with black eyes, a small, round nose, a large mouth that is constantly in a frown, and slightly pointed ears. He wears black jeans with torn legs, and a blue piece of clothing with slits for his arms to go through. He has spiky, blue hair with yellow tips and sideburns, and he wields a gray hammer surrounded by spikes with a green star on both ends that is covered in electricity.
Spark Bonkers appears in Super Kirby Clash as a boss, where he is fought in Seaside and The Ruins. His known attacks include spinning around while swinging his hammer, and finishing off by swinging it into the air, leaving behind a small pillar of electricity that damages anyone on contact, as well as using an electrified Hammer Flip attack and throwing coconuts.
The strongest yet, this hammer hooligan's current is overflowing! Dodge his lightning and smash him to smithereens!”
