What is the name of Syndrome's island base?

What is the name of Syndrome’s island base? It is called Nomanisan Island. The remote island serves as Syndrome’s heavily fortified headquarters in The Incredibles.

Syndrome uses the island as the center of his weapons operation and as the testing ground for the Omnidroid robots. Its facilities include laboratories, guard stations, high-tech vehicles, and a monorail system. The island’s isolation helps him conduct experiments and lure retired superheroes into battles without public interference.

Bob Parr is first sent there under the pretense of stopping an Omnidroid. After completing the mission, he discovers that Mirage and Syndrome have been manipulating him. Helen later follows Bob to the island, with Violet and Dash hidden aboard the aircraft, and the family is eventually captured before escaping.

Nomanisan Island is easy to confuse with Municiberg, the city where the Parr family lives and where the final Omnidroid attack occurs. Municiberg is the urban setting; Nomanisan Island is Syndrome’s secret base and experimental facility.
