Icosahedron 

An icosahedron is a 20-faced polyhedron.

Examples include the decagonal dipyramid, elongated triangular gyrobicupola (Johnson solid ), elongated triangular orthobicupola (), gyroelongated triangular cupola (), Jessen's orthogonal polyhedron, metabiaugmented dodecahedron (), nonagonal antiprism, parabiaugmented dodecahedron (), 18-gonal prism, 19-gonal pyramid, regular icosahedron, and rhombic icosahedron.

It's the only shape with equal power to the octahedron, and was used by Meme Man to defeat Orang.

you cannot defeat me, orang, for i have the icosahedron of capacity.
