Naruto: Uchiha Shentian

After transmigrating into the world of Hokage, he finds himself as Uchiha Shenten, the younger brother of Itachi and Sasuke. Uchiha Shenten is five years younger than Sasuke and ten years younger than Itachi. On the night of the Uchiha clan's massacre, Itachi is thirteen, Sasuke is nearly eight, and Shenten is almost three. Yet no one could have imagined that a baby not even three years old would awaken the Mangekyō Sharingan. Shenten even kills Uchiha Itachi in an instant, then obtains the Eternal Mangekyō Sharingan. This Shenten is truly extraordinary: his Mangekyō Sharingan abilities are resurrection in his left eye and death in his right. His Three-Tomoe Sharingan also has Kamui and Kotoamatsukami. One glare is all it takes to kill Itachi, and then Shenten uses Kamui to fuse with Itachi's Mangekyō Sharingan.
