I am 23 Yrs old & I am a Female.
My favourite Harry Potter characters are (not in any particular order):
Harry Potter, Sirius Black, Fred Weasley, George Weasley, Ron Weasley, Dobby, Minerva McGonagall, Filius Flitwick, Severus Snape, Voldemort, Luna Lovegood, Neville Longbottom, Bill Weasley, Charlie Weasley, Daphne Greengrass, Alastor Moody...
Dolores Umbridge, Bellatrix LeStrange, Rita Skeeter, Sybil Trelawney, Peter Pettigrew, Cornelius Fudge,
Ginny Weasley. (I find her very annoying and I am still not sure how JKR wrote about Harry falling in love with Ginny without him noticing her before his sixth year, and he went on only one date which was disaster... Anyway I cannot criticize a renowned author..)
