1. A Mary-Sue
Uchiha that Itachi
somehow missed during his massacre of the Uchiha clan, despite the fact Sasuke
is the only other to survive.
2. An Uchiha who is even more powerful than Itachi
3. Target practice for Itachi
when he realizes he missed one.
The Suchiha also survived Itachi's massacre, developed Mangekyou Sharingan, has a horrible past, and makes me want to strangle the author.
