Arthur is also dominant over others, especially over Merlin as Merlin is his servant and because of his position as a prince/king, and can be inconsiderate to him sometimes- particularly in the first series. Arthur is also virile and has a love interest in servant Guinevere (who eventually becomes his wife). He also cares about his appearance a lot, we learn this through his dialogue in a scene where Merlin is having to put another hole in Arthur's belt, because that he's too big for it, and Arthur says to Merlin 'not a word of this to anyone'- this suggests that he is worried about what people think of his appearance. The character is also quite intelligent, this is shown through his actions at times and his dialogue at times, particularly in his cleverly worded insults to Merlin.
However, Arthur has many qualities that don't conform to the male stereotype. He becomes more considerate as the series goes on, and becomes increasingly caring and a lot less arrogant. He has dialogue with Merlin sometimes which shows his more caring side towards him. You could say Arthur is independent to some extent, however he does depend on support from his men, Guinevere and Merlin. Furthermore, Arthur breaks the stereotype by not hiding his emotions all the time.
