Mobile Suit Gundam: Ghost

Summary
Mobile Suit Gundam: Ghost takes place in a "what if" variation of Universal Century in which the Unicorn Gundam and it's pilot, Banagher Links, failed their purpose and brought forth the improper use of the contents of Laplace's Box, resulting in utter chaos. Neo Zeon now had a new and undeniable reason to justify their war and with renewed fury launched a string of several successful attacks on Earth, eliminating several critical mobile suit manufactoring facilities and dealing a major blow to the Earth forces. In response, the ESFS imprisoned Banagher Links and began launching their own counterassault.

The series depicts the struggle of civilian Marcus Reval as fate brings him and the new Ghost Gundam together. The fate of the universal century rests on Marcus as his actions begin unlocking the Spirit+, a backup plan should Laplace's Box fail that would either spark the redemption of both sides by restoring the human heart, or unlocking Pandora's Box and finally annihilating both sides as hatred and rage consumes them.
