[HakuUzumakiNamikaze]

Sakura Haruno, Bluma Brief, Rukia, and Nami combined into one character.
Hinata, Chi-Chi, Orihime Inoue, and Boa Hancock combined into one character.
Naruto, Ichigo, Goku, and Luffy combined into one character.
Sasuke, Vegato, Uryu, and Zorro combined into one character.

Better yet, what if we take your combinations and then combine them all into a single character, how would that look?
