Homsar's speech consists almost entirely of non sequiturs, seen when he claims to be the captain of the "Gravy Train" and a "song from the sixties," more often than not prefaced by a bizarre "ah-ahh-ahh!" uttering, although it is revealed in Strong Badia the Free that Homsar is actually an intelligent being, with his way of speaking being a language of his own. However, he has also shown to be capable of speaking coherently over Marzipan's answering machine, during which he refers to his usual manner of speaking as "garbage."
He seems to have the super power of being incredibly awkward, and often defies the laws of physics. In most of his appearances, his hat will either change shape to something, or move around on its own, often orbiting his head. He was created when a fan accidentally misspelled Homestar Runner's name in the second Strong Bad Email, "homsar".
