I myself don't really do that, I enjoy making characters that could be useful to rp as, I do have 2 characters named Shadow though and my user is ShadowMT13, but that is a bit different and I did not intend it to match my user more so the other way around since Shadow is a nickname I was given by some friends years ago, sadly I don't talk to them anymore. I stopped being their friend around age 14 and I am 19 now.
