In the original Ultraman setting, Alien Zarab is the name for an individual representing extraterrestrials from the planet Zarab.
That being appears to be a modernized take on Alien Zarab, a multi-eyed foe of Ultraman.
Shin Ultraman and other “Shin” reboot projects like Shin Godzilla are being incorporated into a new, unified initiative called Shin Japan Heroes Universe.
In the original series, the Science Patrol is hoodwinked by Alien Zarab, who poses as a friend of Earth.
