I also have to agree with Haruki and Lion. There's also really no point in having more than one person basically pointing out the same thing that's already been said before them, really it just makes it look like everyone's ganging up on one person...
Anyway, going on topic, I've had several experiences with this e_e
Originally my name was "Raven" but so many had it, of course, so I had to mix it up a bit until I finally decided to change it altogether haha. You can't really make people change their names, of course, especially if they're very popular characters, but that can't keep you from hoping, eh? xD
There was only one time I saw someone with the name "Katsa", and they had both "Katsa and Fire" in it which are two characters made by the same person, it made me slightly annoyed cause I thought I had finally come across a name that was hardly used but even so it was only once x3
