^^ I'm pretty sure that's Hoho. Initially, I thought it was Ed, but I figured it was Hoho because the facial structures are different and by that small scrap of raggy-looking clothing pretty much confirmed my thoughts.
And I think that Hobo is Hoho. Probably crossing the desert from his destroyed homeland of Xerxes to either Amestris or Xing. You can barely tell by all the context clues in the majority of the ED and those little blonde strands of hair poking out.
