The most underrated characters

[D-ray]

Hi y'all! Since I love character design, and have an interest in deep or just particular characters, I wanted to know which one (from any serie) is considered the most underrated one.

For underrated, I don't mean only by the community, but generally from the show itself (For example: Usagi in the 1987 serie, who is barely used and barely taken in consideration).

So who do you consider a very underrated character? If you can, explain why you think that he shouldn't be, talking about his role, importance or whatever!
