The former BBC Grandstand presenter, who famously came out as a major conspiracy theorist during an interview with the late Sir Terry Wogan in 1991, was interviewed for a YouTube video shown by channel New World Order TV.
In it, he cemented his claims that the British royal family are descended from a reptilian blood line.
Icke subscribes to the Illuminati conspiracy theory that a secret society made up of the royals, political and business leaders actually pulls the strings of world, seemingly democratic governments, from behind the scenes.
But, he adds to this that members of the Illuminati, including all world royal families, and high powered business, and political families are the descendants of ancient hybrids between reptilian aliens and humans.
David Icke has claimed since the 1990s that the royal family are alien lizards.
Icke was asked by the interviewer if he genuinely believed in the theory and where it stemmed from.
He said: “Oh God yes. I did not sit in a dark room and come up with this theory nor go looking for it.
“I have travelled and been to 50 countries to research it.”
He said people all over the globe had provided the same evidence to back up the theory, including CIA insiders.
He said: “It took the form of meeting people who tell of experiences of seeing people, often in positions of power, change from human from to a reptilian form and back again in front of their eyes.”

Icke claimed that ancient texts across the world, including the Bible had accounts of reptiles interbreeding with humans to form these “hybrid bloodlines”.
He said: “The hybrids became demi gods – part human, part god. They were obviously perceived as gods.
“The hybrid blood lines were the ones that became the royal families of the worlds.
“In the Chinese empire, they claim the right to be emperor because they are descended from the serpent god.
“It is all founded on the myth of dragon and they all come from the reptilian connection to justify the right to rule.
“Look at ancient texts and the Bible. Do you really think that the snake in the Garden of Eden was really a snake?
“In texts around the world you find recurring these Garden of Eden situations involve reptilian entities.
“The Hebrew name for snake means two-legged standing upright humanoid reptile.”
Icke claimed interbreeding within the aristocracy was to ensure the bloodlines were not weakened.
He said: “The head of state in the UK is only the head of state because of genetics or bloodline.”
He said the bloodlines spread from the ancient world to the Roman Empire, to the aristocracies of northern Europe.
He said: “The whole obsession of interbreeding among royals and big banking and political families is to hold the genetic structure together because it would quickly be diluted if they bred outside it.”
In order to maintain control, Icke claimed the hybrids had to spread their bloodlines into top political and business families across the globe.

Icke was asked where the reptilians originated from and said it was in space “from outside of the human frequency, the range of visible light.”
He was also asked why, if shape-shifting lizards were running the world, was he able to talk about it and remain safe.
He said: “There are also forces on this planet that do not want this.
“Don’t get caught in the idea they are all powerful.
“If they were all powerful they would have taken over a long time ago, but there is an illuminate of interbreeding families.”
Icke was also asked what he thought of critics of this far-fetched theory.
He said: “I don’t care if people believe it. I’m interested in what is going on not winning popularity contests.”
