oker initially appears to be easy going, cheerful, and a clown, as shown when he intentionally drops balls he was juggling on his head for the amusement of the audience. Despite this outer appearance, though, he is very serious and does not easily give in to emotions. He does seem to care for the other members of the circus, but he puts pleasing Baron Kelvin, no matter how abhorrent he finds his requests to be, above them.
