Dr. Octogonapus is one of the main protagonists/antagonists created by Dom Fera in the YouTube animated series, The Lazer Collection.
Dr. Octogonapus's appearance consists of a grey-colored jumpsuit and four tendril-like appendages that protrude from his back. He wears shiny black glasses, and has orange hair. When expelling pure energy from his mouth, or "Firin' his lazor," Dr. Octagonapus obtains a larger jaw, and red colored lips and teeth . He also is seen with eyes, and is the only time he is temporarily seen without glasses, with exception to a photograph appearing in the Lazer Collection V where his son Randall took his sunglasses.
His third appearance in The Lazer Collection 3 delved into his backstory. First, however, he appeared out of a magic lamp upon being summoned by Aladdin, who badgered him about wishes before the doctor finally lost his temper. Roaring "DOCTOR OCTO-MOTHER-F***ING-GONAPUS!", he incinerated Aladdin in a Shoop da Whoop.
He then unexpectedly burst out of a superhero's chest before blasting his body to ashes.
Later he confronted Detective Randall at the crime scene of the superhero's body. He blasted a lazer at him, who retaliated by shooting at him. He escaped up a building, followed by Randall. He grabbed him by the neck, telling him briefly, "Embrace who you are, Randall," before hurling him back down the building.
Randall survived, and the young detective said that just because of that, things had been made personal.
Later, Randall stopped Dr. Octogonapus from shooping two people and held him at gunpoint, where he was being covered by a comrade of his in a helicopter. He asked the man who the man he was confronting was. In a shocking revelation, upon learning Dr. Octogonapus's name, he realized that he was the doctor's son, as HIS last name was Octogonapus. His tendril arms revealed themselves and his own inherited ability to fire lazers manifested. He was then urged by his father to come with him, as he had much to learn.
He appeared briefly in one skit where he shooped a guy after said guy observed how quiet it was before the doctor's attack.
In The Lazer Collection V, Dr. Octagonapus accidentally shooped and killed Randall, who unwittingly startled him by coming up behind him and saying "Good morning." He later brought out a gargantuan robot to shoop people. He attacked a hobo who was scavenging for food, a food critic who was complaining about having a "sort-of-rare" steak, and the Dirty Boy (only, when his robot smashed the Dirty Boy's piano, the latter was killed by a large splinter from the piano.). At the end of this episode, Cell declared that Dr. Octagonapus was now banished from the Council of Shoop for killing his son, since he had been essential to their "plan".
In the preview, The End scene that he had a head. In the real episode, he accidentally dropped a piano onto a boy that tried to play his trombone because he didn't have his tentacles anymore (a possible effect from having been banished from the Council of Shoop by Cell). Then HE was crushed by another piano.
