Allow me to interject, if I may.

Although these characters tend to irritate me as well, creating a "long-lost relative" to a canon character doesn't necessarily mean instant condemnation, though it does factor into the overall criticism of the character. However, people typically view the character as being part of the entire fandom instead of being exclusive to the creator's reality. Sonic might have thousands of brothers and sisters introduced by the fandom as a whole, but they don't exist in the reality of a single individual.

I suck at explaining things, sorry.
