Everyone has their own opinion of "hot".
In my opinion, Alex Evans http://images.google.com/images?q=Alex%20Evans&rls=com.microsoft:en-us:IE-SearchBox&oe=UTF-8&sourceid=ie7&rlz=1I7ADBF_en&um=1&ie=UTF-8&sa=N&hl=en&tab=wi is quite hot.
Also, Josh Ramsay (who isn't really considered emo, but does have blue hair) Is EXTREMELY attractive. -> http://youcantrewind.deviantart.com/art/Junos-08-Josh-Ramsay-141479469
So hope that answers your question :)
