Can you think of Athos- or D'Artagnan-like characters elsewhere in literature? (The Phoenix Guards and further volumes do not count because I've already thought of them.) Gender is no object if the author doesn't make it one. Half-credit for Porthos- or Aramis-like characters. Quarter-credit for a) other characters that remind you of specific Dumas characters; b) other characters that seem like they belong in Dumas, even though you can't quite say where; or c) comparisons that make me giggle madly.
ETA: It occurs to me that my internal automatic mappings of this question onto Margaret Cho's proclamation about "The Sweet One, The Smart One, and then there's The Ho" may say very disturbing things about what I consider sweet.
