A '''dodecahedron''' was a twelve-sided regular {{w|polyhedron}}, with each side a pentagon.


A dodecahedron is any polyhedron with twelve faces, but usually a regular dodecahedron is meant: a Platonic solid composed of twelve regular pentagonal faces, with three meeting at each vertex. It has twenty (20) vertices and thirty (30) edges. Its dual polyhedron is the icosahedron. To the ancient Greeks, the dodecahedron was a symbol of the universe. If one were to make every one of the Platonic solids with edges of the same length, the dodecahedron would be the largest.

Dodecahedron
Meglos and the Dodecahedron. (TV: Meglos)

A dodecahedron was a twelve-sided regular polyhedron, with each side a pentagon.

The Tigellans used a Dodecahedron as a power source. The Deons, a religious group, believed it to be a gift from their god, Ti.

The Dodecahedron atop the Screens of Zolfa-Thura. (TV: Meglos)

In 1980, the Zolfa-Thuran, Meglos, wished to steal it and use its power to conquer and destroy worlds. Under the guise of the Fourth Doctor, Meglos compressed the Dodecahedron and stole it. He took it back to Zolfa-Thura.

Using the Screens of Zolfa-Thura, Meglos was able to boost the Dodecahedron's power. He planned to destroy Tigella with it but the Doctor reverted the calculations so it destroyed Zolfa-Thura. (TV: Meglos)
