I'm starting this thread to see if there is any interest in the discussion on the topic of younger people being trained for a life of crime fighting, or a life of crime.

the heroes/villains in question can be from any comic universe, and the training can be one-on-one (Batman & Robin, Wolverine & Kitty Pryde), sidekick situation (Wendy & Marvin, Wonder Twins) or a school setting (New Mutants, Generation X, The Hellions).

Discussion can be about the specific training the young people received, or how they used that training in the field. What did you like/not like about these situations? Did you find them realistic/unrealistic?
