Avenger (Japanese: アヴェンジャー, Hepburn: Avenjā) is an anime series, produced by Bandai Visual, Bee Train and Xebec, and directed by Koichi Mashimo. It is set on post-apocalyptic colonized Mars. The series premiered across Japan between 1 October 2003 and 24 December 2003 on the TV Tokyo network. It was later licensed for North American distribution by Bandai's distributive unit across the region, Bandai Entertainment.
The story is set on a colonized Mars at some unspecified point in the future. The majority of the human population is divided up into a number of small domed city-states. Those who live outside the domes in the harsh wildernesses of the planet are known as Barbaroi. Resources are scarce, and supplies are divided out between cities based on the outcome of gladiatorial battles between representative fighters from each. Adding to the problems of the colonists, no children have been born on Mars for a decade. The cause of the infertility is unknown, but people have turned to robots called dolls as a substitute for the presence of children in their lives. And a red moon, Earth's moon, hangs over Mars, drawn towards the red planet after the destruction of Earth and ravaging it with lunar storms caused by gravitational fluctuations between Mars and its unwelcome satellite.
You see the chaos in the streets
You feel your world is ending
So much violence has begun
Nowhere to turn your hope is gone
Yes there is something you can do
To pull you through the last days
Oh yes it's true believer
Take up arms and fight
(Arm yourselves and fight)
(Stallions dressed in white)
(You can choose your side)
Angels Of War
You feel the darkness fill your soul
You feel your life is ending
Angels Of War
