For Clarity, I want the pair of MENTOR, and APPRENTICE. If the character has worked with more than one, I will still force you to narrow it down to the correct one.

None from Japanese Media. All of them have fought against something, or someone. Unless stated they are all male. No Fighting Games No Superhero characters None from the Karate Kid None from Zorro, or any relation to.

*6.) The answer is Carol, and Mika/Lizzie Samuels, from The Walking Dead. Answered by /u/AweKartik777

*The character worked with two people at the same time. I will accept either one for the answer.

**I'm going to give just an extent, and a change to 4. The movies came out during 1976, to 1990 in the original series of movies. Everything else is still the same, I was under the presumption that it was different.

Four also has two movies in 2000's/2010's, but those are not counted because they do not involve the mentor/aprentice that I'm thinking of, even if they were mentioned in those two movies.

For 1 and Six. Both of there respective series are still going on, as said before. In both examples, a character dies. For One, the Mentor dies. For Six, the apprentice[s] die.

For 1. The game series is made by a famous developer of these types of games. And have worked with multiple other franchises in the past.
