Neo Human Casshan

The brilliant Dr. Azuma created many robots to aid humankind. However, during a thunderstorm his lab was struck by lightning, corrupting the programming of one of his robots, BK-1, who renames himself Braiking Boss and declares that instead of serving mankind, mankind will now serve him! He brings other robots together into an overwhelming army bent on enslaving the human race. Tetsuya, Dr. Azuma's son, asks his father to turn him into an indestructible android so that he will have the power to destroy the threat his father inadvertently created. Shortly thereafter, Braiking Boss captures Dr. Azuma and his wife, Tetsuya, now renamed Casshern, sets out to turn the tide of the war and rescue his parents, with the help of his girlfriend, Luna, and robot dog, Friender.

Hurricane Polymar

Yoroi Takeshi is a carefree and somewhat naïve youth, who works as an assistant to the bumbling detective wannabe Kuruma Jo (who frequently proclaims himself the heir apparent to the title of Greatest Detective “Sherlock Holmes”). From their rundown and shabby office, they run a humble if not failing private investigation service. The spunky and cute Nanba Teru (who’s father owns the building when Jo and Takeshi reside in) frequently interferes in their affairs by threatening eviction (Jo is continually months behind in back rent). Since they rarely get any clients, they must resort to eavesdropping and spying on the Secret International Police Department headquarters, located in the building across from theirs in order to get their assignments. Unbeknownst to Jo and Teru, Takeshi has a deep secret. Not only is Takeshi the son of the International Police Department Chief but in times of peril and danger, mild-mannered Takeshi uses his trusty Poly-Met (Polymer Helmet) to transform into the Superhero “Hurricane” Polymer, a red suited masked man with incredible fighting abilities and superhuman strength. The only one who knows Takeshi’s secret is his lazy Saint Bernard, Daisaku, who always likes to provide cutting commentary to the audience (using his inner voice). Together Jo and Takeshi (as Polymer) confront and battle a myriad of evil organizations, criminal gangs, mutants and monsters as they fight crime in the future city of Washinkyo (Washington/Tokyo).

Eagle Riders (2)

After Leader X is seemingly destroyed for good at the end of Gatchaman II, a fragment of him that survived grows and mutates into Z. With the head of the Egobossler family, Count Egobossler (and his two subordinates Mechandol and Kempler), Z is bent on destroying the Earth, and the Science Ninja Team, once more. In the wake of Anderson's death, Dr.Nambu has become the new head of the ISO, while the team is now confined to the Gallatown (aka "G-Town") underwater base. Engineer Kamo is introduced, and after the New GodPhoenix is destroyed early on, the team receives the new Gatchaspartan as their mecha. The Gatchaspartan has a special mode as well, called Hypershoot, that can only be utilized by Ken (with his new "Gatchafencer" sword). As the series progresses, it is learned that the radiation exposure from constant use of the Hypershoot is slowly killing Ken, and that continued use would mean death. Meanwhile, Z plans to destroy the earth with an antimatter asteroid, codenamed "Poison Apple".

God Mars

In the year 1999, humanity begins to advance beyond the solar system. The leader of the planet Gishin, Emperor Zule, aims to conquer the galaxy and ends up in a conflict with Earth as a result. In an act aimed to eliminate the Earth, he sends a baby named Mars to live among humanity. Mars is accompanied by Gaia, a giant robot that utilizes a new power source strong enough to destroy an entire planet. Once Mars grows up, he will destroy the Earth by activating the bomb within Gaia. However, upon arriving on Earth, Mars is adopted into a Japanese family and given the name Takeru. Seventeen years later, Takeru has grown a love for humanity and he refuses to detonate the bomb as ordered by Zule. However, the bomb within Gaia is set to explode if Takeru were ever to die, which would ultimately result in the Earth's destruction. Takeru possesses psychic powers (ESP) and decides to join the Earth defense forces and becomes a member of the Crasher Squad (an elite space defense force) where he and his friends take a stand against the Gishin attack. Unknown to the Gishin, five other robots were created in secrecy along side Gaia by Takeru's father and sent with Gaia to protect Takeru. The five other robots are Sphinx, Uranus, Titan, Shin and Ra. Whenever Earth is in danger, Takeru is able to summon the five other robots to combine with Gaia form the giant robot Godmars.

Gatchaman

Due to dangers of decreasing resources and growing pollution, the International Scientific Organization is established to improve environmental conditions throughout the world. But an international criminal group, Gallactor, tries to achieve world domination by taking control of the ISO. Gallactor was created by a mysterious being from outer space known as Generalissimo X, who gives orders through its chief commander on Earth, the masked Berg katse. To fight Gallactor and its robot monsters, the ISO's Dr. Nambu enlists five brave youths into a combat squad called Gatchaman,the Science Commandos. Special scientific powers and dramatic birdlike costumes make the Gatchaman Squad a match for Gallactor, wherever on Earth it may strike. Ken(the Eagle) is the wise leader, assisted by sometimes-foolhardy Joe(the Condor), pretty Jun(the Swan), eager little Jinpei(the Swallow), and strong Ryu(the Horned Owl). Each has individual scientific weapons, but their main power lies in their aircraft, the Phoenix, which can transform itself into a fiery arrow capable of piercing the most massive threats. GATCHAMAN is a series of dynamic action and tension as ken, Joe, Jun, Jinpei, and Ryu hold themselves in constant readiness to meet each new threat by Gallactor to conquer the world.
