The Carbon Onion is a species of Carbonite appearing in Pikmin: Neo. They are bulbous objects displaying the same black-and-purple color scheme as the carbon fluid they produce and form when large masses of carbon fluid converge to spread further. They stay on the ground, their fleshy veins coming from their mass, assimilating the local environment into producing and spreading carbon fluid and growing their territory. These territories are classified as carbon biomes and tend to cause the local wildlife to risk contracting the carbon virus. The fluid they produce is indestructible and is fatal to all Pikmin types. Those that drown in the substance are assimilated, and the Carbon Onion creates doppelgangers called Carbomin, which protect their birthplace much like how a Pikmin protects their Onion. They are resistant to the extreme cold of ice and the extreme force of explosions, meaning they can dwell in any biome, although they are vulnerable to the energy of fire and electricity, as those substances instantly destroy them. Once a Carbon Onion is destroyed, all carbon fluid in its range becomes destructible, and all carbon-assimilated creatures and Carbomin created by it collapse into a light mist.
