I find it intriguing that he's been doing the CD character for 15 years now.
With little change! When I'm watching some of my favorite YouTubers, they have changed both delivery and looks quite a bit. The Captain stays the same. Alan does so, too, but I suppose that's because he isn't paid enough to afford changing anything.
Changing The Captain would be like Jim Henson changing Kermit the Frog. No, no, no.
