Sasuke Uchiha deserted from Konoha when he was 13, leaving his beloved Naruto behind at that time. When they grew, at the age of 17, Orochimaru created an embryo and once it was born he was called Menma. Orochimaru had noticed that not long ago Sasuke had sneaked Naruto into the hideouts, and he had a test for them: taking care of a baby that looked like their perfect combination....

Naruto was surprised, he had escaped for Sasuke, but he never expected this, and of course neither did Sasuke.

Sasuke grew accustomed to the baby's presence on his life, he would stare long periods of time at the baby's bright blue eyes that looked so similar to Naruto's... Sasuke grew attached to Menma.

One day Sasuke was holding Menma in one arm as he practiced with his Katana with the free one, little Menma babbled and tugged at Sasuke's hair... Just then Sasuke saw Naruto appear from the woods, their relationship isn't official btw, they're still friends.

Sasuke: Dobe. Escaping again from Konoha? I told you already I won't let you take Menma there. I don't want you and those asses to keep him.

When the baby saw Naruto, he started doing grabby hands while wiggling on Sasuke's arm. Menma: babbles mama...
