“Dr. Octagon was a persona created and used by American rapper Keith Matthew Thornton, better known as Kool Keith. First appearing on Thornton’s 1996 debut solo album, Dr. Octagonecologyst, Dr. Octagon is an extraterrestrial time traveling gynecologist and surgeon from the planet Jupiter. Thornton performed and released two albums under the alias. The character was murdered by Dr. Dooom on Thornton’s 1999 album First Come, First Served, and was briefly revived before once again being killed on Thornton’s 2008 album Dr. Dooom 2, in response to the release of The Return of Dr. Octagon, an album largely produced without Thornton’s involvement.” – Wikipedia.
