Colonel Sanders

Colonel Sanders (1890 - 1980), yes, that Colonel Sanders, is the figurehead of Kentucky Fried Chicken (KFC) and was at one point a real person, making a few cameos in Dynamite Düx for no real reason, other than (presumably) product placement. In the Achacha World, the Colonel apparently never died, unless the player is to assume that Düx takes place in the past, or that history is different over there.

Wait, what?
Many people are, quite rightly, confused as to why he's in the game in the first place, and no amount of research online has been able to explain how Sega AM2 were able to use the likeness of the colonel in the game, so one is left to assume that either KFC allowed Sega to use it as a form of cross-advertising and had some sort of brand deal with KFC, or this was done illegally without the expressed permission of the company and Sanders' family, which is presumably not the case. It would explain why the colonel was removed from the ports, though.

Physical description
Colonel Sanders appears in his trademark white suit, with black-rimmed glasses and black cravat. This depiction of Sanders is the one that is generally associated with KFC, i.e. how he looked in the late 50s until his death in 1980, though his facial hair has been toned down slightly due to sprite size limitations.

Role in the game
The Colonel referees the Bin vs Pin boxing match bonus stages that are present in the arcade version of the game, outside of his brief cameo at the start of the game. This leads me to believe that his inclusion was a joke by the developers, and a fully licensed one at that, as it doesn't really make much sense to believe Colonel Sanders would referee a boxing match, but then again, him being in the game at all doesn't make much sense.
