Captain Kirk (Star Trek), the Doctor (Doctor Who). When I started updating triangle caricature fanfiction cartoons under the title The Hero of Three Faces, I chose redrawing this gag from the previous history of my fanfiction cartoons as the initial one because I like it for including and contrasting Doctor Who and Star Trek, my two all time favorite franchises - or my two favorite fandoms as fandom these days is wont to express it. That first Three Faces cartoon included Captain Picard instead of Captain Kirk because Three Faces' crossover chronological continuity paradigm was different for the first few years of the title, as can be seen from the two diagrams at the bottom of the About page, or at cartoon aapv when the change was implemented.
