Super Dimensional Cavalry Southern Cross

In the year 2062, the world's two superpowers are fighting a long and brutal war. In a desperate attempt to win, pilot Kei Katsuragi is given the mission to detonate a super weapon called the Space/Time Oscillation Bomb. The bomb explodes but the results are completely unexpected: a multitude of dimensions, times, and realities are unleashed into the world. Can Kei reverse the effects and bring life back to normal?

The year is now 2041 AD. A new enemy called Zeravire suddenly appears in the solar system, destroying all military installations it comes across. However, a wealthy man named Klein Sandman is already aware of this planned invasion and had been secretly preparing his army for battle. His trump card is Gravion, a giant robot that utilizes gravity as its source of energy. Meanwhile a young man named Eiji secretly enters Sandman's base in search for his missing sister. It is there that he meets another young man by the name of Toga... These two must now fight together with four other individuals aboard the super robot, Gravion to fend off the Zeravire threat.

For 200 years they lay deep beneath the earth or silent on the ocean bed. Now two opposing armies race to unearth these massive engines of war, devastating weapons known as Decimators. As more of these vast robots are reactivated, the world moves ever closer to another all-out war, drawing innocent victims into the deadly conflict.

In 1999, a giant alien spacecraft crash lands on South Ataria island. Humanity proceeds to attempt to rebuild this marvel, but political conflicts centered around the Macross result in a global war. After 10 years, the Unification Wars are finally over, the new Earth United Nations Government is in power, and work on the Macross is complete. On the day of the launching ceremony, its main cannon fires on its own, destroying an alien spacecraft. This fateful day marks the beginning of the war between the humans on the Macross and the Zentradi, a race of humanoid aliens of giant proportions.
