Gundam: The Crimson Will

When the genius quantum physicist Dongfang Yi, from the year 2050, awakens during the Battle of Loum, the bloodiest battle in the history of humanity in the Gundam universe's Universal Century, he discovers that he has transmigrated into Will East, a Federation pilot and spoiled heir to a family representing one of the Earth Federation's G8 nations. This isn't a simulated game. It's a real hell of blood and iron. When a scientist's extraordinary intellect combines with an ace pilot's combat instincts, and the potential of the legendary Newtype awakens within the two fused souls, a hero destined to save the Universal Century is born! (The protagonist will transmigrate into parallel counterparts across different Gundam universes and timelines. The first world is UC. P.S. Some settings will draw on 0079, while others will be based on GTO.)
