Edo is a character from the Ultraman manga and its anime adaptation, presented as the last known survivor of the Zettonian race. His people were nearly wiped out during a failed invasion of Earth, an attack that was thwarted by the original Ultraman. In the modern era, Edo has taken on a position of authority, serving as a key representative for the Star Cluster Alliance and acting as the head of the Science Special Search Party, or SSSP, the organization tasked with protecting Earth from alien threats.

Edo’s personality is defined by a complex blend of diplomatic pragmatism and underlying ambition. He is highly intelligent, calculating, and displays a manipulative streak, often orchestrating events from behind the scenes to achieve his goals. While he initially appears as a calm and supportive mentor to the protagonist, Shinjiro Hayata, his methods can be ruthless. He has been known to stage public battles involving hired aliens to forcefully accelerate the development of Shinjiro’s powers and to expose humanity’s reality of extraterrestrial life. Edo’s motivations differ between the manga and the anime. In the manga, his role is more aligned with that of a shrewd strategist working to secure Earth’s place within the intergalactic community. However, in the third season of the anime, his role shifts dramatically, revealing him to be an overarching antagonist whose true intention is to dismantle Earth’s peace and corrupt Ultraman’s legacy as part of his own species’ resurgence.

Within the story, Edo is the de facto leader of the SSSP, a position that puts him in charge of operations and the development of the Ultraman suits. His most significant relationship is with Shinjiro Hayata, whom he recruits, manipulates, and mentors as the successor to the Ultraman title. He works closely with the SSSP scientist Mitsuhiro Ide, who acts as his assistant and confidant, as well as with the field agent Dan Moroboshi. Despite his leadership role, which requires cooperation with the very organization that led to his species’ downfall, Edo’s interactions are often laced with a deep-seated, unresolved conflict regarding humanity and the memory of Ultraman.

Physically, Edo is a short, lightweight humanoid alien standing two meters tall and weighing only six kilograms. He uses a holographic mimicry device to project a human form, allowing him to walk unnoticed in society. In the anime, Edo possesses notable combat abilities, primarily through the use of a specialized Zetton Suit. This suit of armor is equipped with a visor capable of firing pink lasers, as well as four back-mounted mechanisms that can each deploy their own laser weapons.
