Anderson wields ultimate authority as Director of the International Science Organization (ISO) during the original series. He chairs meetings with international representatives to combat global threats like Galactor and oversee initiatives such as the Mantle Plan. Despite his leadership role, Anderson possesses significant scientific expertise, understanding complex concepts including nuclear power and neutron reactions. He personally handles critical ISO operations, transporting sensitive components like the ultracomputer core aboard his specially equipped private jet. This jet features an ejector seat with a built-in radio for Morse code transmission and secure storage compartments. Anderson enjoys cigars during downtime. Initially unaware of the Science Ninja Team formed by Dr. Nambu, Anderson later learns their civilian identities but cannot issue direct orders. Operational command remains solely with Dr. Nambu, though Anderson requests their assistance in crises, developing respect for their capabilities over time. He defers to Nambu's scientific and security judgments, consulting closely on Galactor activities. Anderson maintains oversight of allied forces like the Red Impulse Squadron through the ISO's Information Bureau. Anderson sustains critical injuries during a Galactor attack on the 1st Naval Command in *Gatchaman II*, where he supervised development of specialized radar technology for the Science Ninja Team. This attack introduces his grandson, Sam. Anderson succumbs to these injuries off-screen between series. His death results in Dr. Nambu becoming the new ISO Director in *Gatchaman Fighter*. In the OVA series, Anderson retains his role as ISO Director. He attends high-level meetings where Nambu briefs officials on Galactor threats, witnesses military decisions jeopardizing the Science Ninja Team like the premature attack on BC Island, and participates in strategic discussions during Galactor ultimatums. His presence remains consistent across all three OVA volumes, though narratively minimal. For the *Battle of the Planets* adaptation, elements of Anderson and Dr. Nambu merge into "Chief Anderson." This version heads security for the Intergalactic Federation, serving as direct superior to G-Force. He briefs them on missions, occasionally accompanies them aboard the Phoenix, demonstrates extensive scientific knowledge analyzing enemy technology, and oversees projects like the Lorelei rocket program. This Anderson acts as a mentor to Mark (Ken), having raised him after Colonel Cronus departed. His personality is stern and rule-oriented, prioritizing protocol even during crises.
