Twoheads were a species of cobweb spider closely related to the Pumpkin Twohead, the Ariados, and to a lesser extent the Happy-faced Spider. It was endemic to the Johto region. It was discovered only briefly in 1997, and evidence of its existence was revealed in 2018. It is now considered to be extinct, possibly out-competed by the much more successful Ariados.
When a Twohead is born it is know as a Kokumo. These juveniles are difficult to differentiate from the juveniles of Ariados, known as Spinaraks. Notable differences are that the tip of their abdomen is slightly more pointed instead of the rounded edge of a Spinarak's abdomen, and their fangs are black instead of red. Since all known images of Twoheads are monochromatic, it is unknown if their colors were different than their contemporaries, though the related Pumpkin Twohead is known to be primarily purple and red.
Similar to Ariados, Twoheads have lost one pair of legs which never develop in the egg and do not grow in during any of its moults. The same has happened with six of their pairs of eyes, and as such they only rely on their primary base of eyes. Facial markings on the back of the body make it appear that they have a second set of eyes, but these are false and presumably meant to deter predators.
Upon reaching maturity, the juvenile's singular horn splits into two and their fangs lighten in color. The abdomen markings become more dreadful in appearance.
