He might be a Nordsee promotional figure; Playmobil have linked up with the Nordsee chain of fish restaurants in the past and created figures which appear nowhere else. They had three pirate theme figures last year (two pirates and a Spanish soldier) with a mini-game, and the pirate theme seems to tie in with their nautical nature.
Alternately he might be a figure representing a historical personage or theme, like the Knight of Malta figure. I have a couple of these, but they are not made available through the normal channels. There was also that Prince of Somewhere figure they did for a particular museum in Germany.
The Pharoah figure which was similarly packaged for a German Toy Show last year (I forget the exact details) has turned out to be much more common than I expected, and is now available as figure 7382 in the UK, so I'm glad I didn't spend £££s trying to snap him up on evilBay.
I don't think this is intended to be coloured with marker pens, or why would the legs be black?
