Naruto

Masashi Kishimoto came up with narutos name while eating ramen, and based Naruto's backstory on his own past experience as a child.

Naruto's whiskers is missing when he accidentally kisses Sasuke.

In the Japanese version of the anime series, after Naruto does the Sexy Jutsu (in both the first and second episodes) there is blood coming out of either Iruka, The Third Hokage, or Ebisu's nose. In the English release of the anime, this was completely altered to make it appear that the characters were falling backwards (something that happens frequently in anime when an unexpected event occurs). But for some reason, in the episode 2 dub, after the 3rd Hokage "falls backwards", he gets back up, and there is a trace of blood on the handkerchief under his nose, suggesting that he was only bleeding a little bit.
