I could easily be ignorant of some work that's been done on this subject, but, at least in my experience, the evidence for the Jesus of Revelation has been neglected. We hear a lot about the Jesus of the Synoptics, the Jesus of the fourth gospel, or the Jesus of Paul's letters, for example, but seemingly far less about the Jesus of Revelation. Given how much Revelation has been criticized over the years, even by professing Christians at times, and given the importance of what Jesus says and does in other contexts in the book, the evidence for the Jesus of Revelation ought to get more attention.
