Nagato (Earth-11201984)

Nagato is a descendant of the Uzumaki Clan, making him a cousin of Naruto Uzumaki and Karin. After he became an orphan, the legendary Jiraiya adopted him and his friends Yahiko and Konan. After they became of age, the three friends became the assistants of world renown scientist Dr. Gero. The three, along with Gero's other assistants Hachiju and Nanaju, helped create Android 13, Android 14, Android 15, and Android 16. Eventually, Gero was roped into a secret society called the Android Army, with other members including Danzo Shimura, Dr. Wheelo, Sektor, and Dr. Kotchin. At first what they did was work on robotics and bio engineering, working on Project: Cell, however, Danzo and Dr. Wheelo started distorting the views of the Android Army, eventually becoming a terrorist organization with aspirations of world domination. When Dr. Gero tried to speak out against the other members, the retaliation was Nagato having his back broken, and Yahiko recreated into Pain, a modern day Frankenstein's monster. Nagato was tended to by Konan, who eventually helped him create a back brace to help him walk, and he started to help Dr. Gero instigate the downfall of the Android Army with the aide of the Z Fighters and Android 16. After the downfall of the Android Army, Nagato and Konan joined the Z Fighters in fighting off a freed Cell. Afterwards, Nagato and Konan found an egg laid by Cell, and out of the egg came Cell Jr., which Nagato and Konan adopted as their son.
