A light purple cat Furfected. Parts of its body are made of black crystal-like material. There is a yellow core-like object in the center of its body. It is a Crawler type among the Furfected. It possesses attack, infection, and Core Attack abilities. If killed by a Core Attack, the victim simply dies. Speed is normal. Infection: Occurs via the purple and black mixed crystals in the Crystal Cave.

A white cat- or fox-like Furfected. The tips of its ears and tail are multicolored. It is an Alpha type among the Furfected. It only has attack and infection abilities. Speed is on the faster side.

A white dragon Furfected with yellow patterns and yellow wings. It is a Flyer type among the Furfected. It has a standard attack and a bat embedded with yellow crystals. If killed by this bat, the victim turns into an Angel Dog (a quadrupedal dog). This weapon replaces its infection ability; therefore, if the bat is broken, it cannot infect others. Speed is on the slower side. Infection: Occurs via the 'Old Syringe' that appears in the closed facility during a blackout and the white sample always found in the lab. However, the syringe must be used first followed by the sample; if the order is reversed, the skin will necrose on the spot.

A hyena Furfected with yellow and orange fur, wearing a white mask with white horns. Buried Drakey is an Alpha type and possesses attack and suppression abilities.

Its pupils are usually black but glow red when using suppression. Speed is normal. Infection: Occurs via the orange liquid that occasionally appears in the Lab Test Room or Room 1 of the closed facility during blackout or carrot events.
