From Homestar Runner Wiki
Strong Man (also The Strong Man) is the Old-Timey version of Strong Mad. He doesn't talk, so he just growls and moves his eyebrows. He doesn't really move his legs, so he moves around by sort of bouncing from side to side. However, he can dance fairly well. The fact that he is always facing the camera may be a reference to Marshmallow's Last Stand, in which his modern-day counterpart was only seen from the front. It should also be noted that Strong Mad misspelled his own name as "Strng Man" in Yearbook Character Page.
