Meet Gatchaman, the Science Ninja Team
designed by the International Science Organization's chief of Science Spy stuff.
Then meet a Mecha, in this case the gigantic Robot Turtle King, operated by a commandor with an octopus mask/helmet on from Galactor
This episode cuts to the point: the dark and impulsive Joe the Condor ("Jason" from the US version) and Ken, the team leader ("Mark" in the US version), have power conflicts regularily; bad guys want to rule the world; and that isn't happening on a Science Ninja Team's watch.
Hell, the one female member of the team, Jun ("Princess" <wince> in the US version) is the explosives expert,
...and she loves her job!
The other guys are Ryu and Jinpei (Tiny and Kee-op in the US): the heavy-set Brooklyn-accented pilot of the God Phoenix and the weird, hyperactive kid. Ryu wore an owl bird costume, while Jinpei was the sparrow.
This episode is gold just for the sake of its showing some really kick-ass fight sequences, plus, an introduction to the requisite Firey Phoenix function that their air-tank-jet, the God Machine has, at the risk of the health of the team!
From Wikipedia.org:The Gatchaman team employed a unique style of highly violent and effective martial arts, developed by Dr. Nambu, that drew from their physical abilities to enable them to perform superhuman feats, akin to their avian namesakes, such as high-speed run and flight, high jumping, silent movement-attack and the like. This fighting system was known as "Science Ninja Technique" (科学忍法 Kagaku Ninpō), and it is mentioned in the original Japanese lyrics of the Gatchaman theme song. The team members also used various signature weapons and mecha-style vehicles; each had a more mundane-looking disguised form. To change modes, each member is equipped with a special wrist device that, aside from being a communicator and tracking device, enabled the change when the proper gesture and voice command "Bird, Go!" was given. Their vehicles were docked in the team's main vehicle, the God Phoenix, a supersonic plane capable of underwater travel and minor space flight as necessary. The God Phoenix was armed with an unspecified but large (roughly 30+) number of Bird Missiles that were fired from a rack system mounted atop the center section. After the original God Phoenix was destroyed by an octopus-based mecha, an improved version carried a pair of Super Bird Missiles in twin drop-down pods from the bottom center section, which could be fitted with either a warhead for attack or a manned capsule to carry a passenger for a boarding operation when it successfully impacted into an enemy vessel. The ship also could have an energy-beam weapon that was deployed by sliding, which opened the nose doors for the weapon apparatus that was mounted on the same frame holding Joe's car, but its solar power source was unreliable because of its sensitivity to any interfering cloud cover. In addition, when necessary, the plane was able to temporarily transform into a massive bird of flame like the legendary Phoenix to escape danger or as a powerful attack, although the process itself endangered the team because of the extreme pressure felt in the passenger cabin.
