Appleseed

After facing massive destruction from a devastating war, the city Olympus has become the last stronghold as the center of command for the world. In order to protect the city from a group of terrorists known as the Argonauts, former LAPD SWAT member, Deunan Knotts, runs special military forces consisting of Biroids (cloned humans) and her cyborg partner Brialeos. Knotts must protect the city at all costs but is met with difficulties when Al Ceides, the Argonaut leader thought to be dead, resurfaces and causes problems.

Growing out of the chaos of a global war, the city of Utopia is populated by humans and bioroids (artificial humans). On the surface, everything is harmonious, but tensions lurk. Into this seemingly perfect society comes a survivor of the wars, Deunan Knute, who carries a legacy that will turn out to be of critical importance to the future of humanity.

Appleseed Alpha depicts the early days of Deunan Knute and Briareos in the 22nd century, as they embark on a journey throughout dystopic ruins of New York in search of the city of Olympus. They are hired by Two Horns, the warlord of the ruined city, to eliminate bipedal combat machines. During the fight, they encouter Iris and Olson, both on a mission. Deunan and Briareos befriend with them and decide to join their mission. Iris is tasked with preventing the malevolent cyborg Talos from capturing a secret weapon humans were building. Talos uses Iris to activate the gigantic war machine.

Deunan, a young female warrior, and Briareos, a veteran cyborg-soldier, are both partners and lovers. As members of E.S.W.A.T., the elite special forces serving Olympus, they are deployed whenever trouble strikes. The two fighters find their partnership tested in a new way by the arrival of a new member to their ranks - an experimental Bioroid named Tereus.
