User blog comment:Thunderboltshock/How to make a good backstory for your character/@comment-5842470-20140312032925

Many of those long-lost canon-siblings are made for one reason; to explain the apparent absence from the games/comics. They're a way for the character to be related to mains without completely screwing over canon. Not saying I support such a thing (Unless it's done very well.), just tht that's the main reason fot it. (I, myself try to avoid using canon characters.)
