Sai (Earth-11201984)

Sai is a genetic hybrid created between Danzo Shimura and King Cold, as insurance to a lasting legacy because they knew King Cold's children, Frieza and Cooler, would have killed each other one day. Danzo originally created Sai so that he could be a means of world peace, before Danzo's view of the world became corrupted, deformed, and mutated by war and his rivalry with Hiruzen Sarutobi into making Danzo obsessed with ruling the world, with the Android Army of Dr. Wheelo. Sai was left in hypersleep for years while Dr. Wheelo, and his assistants Dr. Kotchin and Dr. Gero worked on Cell. When the Z Fighters raided the mountain headquarters of the Android Army, Dr. Gero released Cell onto the Z Fighters. However, Dr. Gero, disgusted with what has been done to his dead son's memory, he released Sai as well, and Gero and Sai proved the deciding factor in the defeat of the Android Army, but was nothing more than a spectator in the Cell Games. Afterwards, Sai fell in love with Ino Yamanaka, with whom he had a son named Inojin, and both participated in the World Martial Arts Tournament with the other Z Fighters, and both aided the fight against Majin Buu.
