The Shopkeeper, or more properly Shopkeepers, are a group of supportingcharacters in Double Dragon Neon. They are five identical (presumably twin) brothers who each runs a "Curio Shop" in one of the levels of the game. They can be found attending the shops in Missions 2, 3, 5, 8 and 10. Each of these shops sells power-ups, extra lives and its own special selection of mix tapes.
Unused concept art for the game (possibly of an enemy that didn't make it to the final release) includes sketches of two creatures that strikingly resemble both a mogwai and a gremlin, further reinforcing this reference.
The Shopkeeper is voiced by Len Smith, who also voices Abobo and Williams.
According to him/them, the Shopkeeper(s) is/are the father(s) of all the different Shun enemies encountered in the game.
