Angels in the Bible, can look like you or me. We never know whether we are "entertaining angels" when we do unto others, which wold make one believe they can be like us in appearance. Secondly, they were in O.T. times large and intimidating and their countenance was frightening. I do not find specifics about their look, but they are bodily and "like us" in appearance when here to do God's intervention and ministering work.
