User blog comment:Stone Roger/Natsu and Zeref have somekind of relation?/@comment-86.161.239.29-20130606112107

i have to agree. The two of them look a like in my eyes, so i thought that maybe they were brothers. There may be a chance that Natsu is his brother and either he was made to sleep for 400 years and doesn't remember it or Zeref was re-born as his twin brother. There is also the slight chance that they are father and son. But taking into account Zeref's personality i doubt that is the case.
