Everybody know (maybe) this minifigure from the Pirates theme but....
It's not that!
Whit this post I would ask to eliminate the connection between the character of the "Lieutenant De Martinet" with the minifigure of the generic Imperial Officer present in the LEGO sets because don't exist!
In fact, there is no official reference to the fact that that minifigure is a representation of the character of Lieutenant DeMartinet present in various comics, radio dramas, books, etc. In no catalog or magazine that minifigure is connected to him! This is an inaccuracy transmitted by mistake over time! In addition, the minifigure in red mustache does not look at all like the character present in the various merchandising while other characters, like Redbeard, are very loyal to the minifigures counterparties!
