In Pikmin Chronicles
Two types of Parasitic Pikmin appear in Pikmin Chronicles: Bulbmin, the Pikmin that infect bulborbs, and Green Pikmin, sometimes known as Dwarf Bulbmin, the result radiation exposure has on Bulbmin.

Bulbmin are bright orange, have hair-like protrusions on their heads, sharp claws, and lightly bloodshot eyes with pink irises. They are very aggressive and live in bright orange Onions, which may appear at random in some environments, and do one of two things: they land on the ground and release Bulbmin, or eject seeds, both of which contribute towards the limit of on-field Pikmin. Since they share the same plant-animal heritage, Bulbmin and other Pikmin will not attack one another. They are aggressive toward leaders even when plucked from the ground by them. Leaders can shake off attacking Bulbmin to defend themselves and can punch them until they die, although they can be led into hazards they would normally avoid while passive. The Bulbmin Onion can be attacked after it lands, and if attacked sufficiently, it will fly off to land in a different location in the same environment.

When exposed to radiation, Bulbmin shrink to about half of their original size, making them the smallest of all known Pikmin, and turn a strange shade of green, with their hair falling out, claws lengthening, and eyes becoming yellow and blank, to become Green Pikmin. Aside from their speed and hostility, Green Pikmin are especially dangerous in the sense that they can control other Pikmin. These Pikmin are viewed as threats by other Pikmin, and so will attack one another.

In Pikmin: Advanced Online
Parasitic Pikmin appear in Pikmin: Advanced Online as the Pikmin species that parasitizes grub-dogs to create Bulbmin. Their Onion is found at the Snowtop River Palace.

In PNF-404 Pet Shop
Bean Pikmin are a type of Pikmin that parasitize small creatures, mostly members of the grub-dog family, but could theoretically parasitize any creature. They are taller and lankier than the average Pikmin, and are green in color. They are seldom seen not a part of a parasitized creature.

The only way to see a Bean Pikmin is by awakening a bean Dormant Onion.

Description
"The lanky Bean Pikmin are seldom seen in the flesh, and usually parasitize smaller creatures, usually juvenile grub-dogs. Dispite their lanky appearance, theoretically, a Bean Pikmin could parasitize any creature and transform it into a Pikmin, mostly because of their ability to root itself inside the creature’s body, leading to the sprout of the Bean Pikmin burrowing out of the skin of the affected creature."
