I think my favorite part of dc comics is its history and relationships between characters, so I wanted to do a poll and I guess discussion on peoples favorite mentor relationship. Basically heroes training other heroes and the friendships/respect that they develop through training and such.
For me my favorite will always be Wildcat training Batman to fight. I like it because Batman is generally treated/depicted as this ultimate fighter, someone who has planned for everything and even though he is a mortal man is still someone not to be trifled with. But there is something I like about the idea that at one point Bruce before he was Batman had no idea what he was doing, so he approached a golden age hero/boxer to help train him how to fight. That to me establishes what I like about DC history, there was a golden age that came before the modern age and they helped inspire and train the heroes that we know today and nothing says that more to me then the training of Batman.
Anyway like I said feel free to vote and describe in a post who you like.
edit: Meant to have an other option on the poll, my bad. Just write in the comments if there is a relationship you like outside of what I listed.
