Disturbing Video Game Music 193: Dream Eater - Pokemon Mystery Dungeon Red and Blue Rescue Team
Perhaps the best spin-off in the Pokemon franchise, the Pokemon Mystery Dungeon games are roguelikes where you actually play as a Pokemon and with your party explore big randomly generated dungeons to complete quests and face bosses.
In the first game in the series you are a human who is turned into a Pokemon and with the help of your new Pokemon friends investigate what exactly has happened as well as help the locals. A constant thorn in your side is the villainous Gengar, while he initially seems to be a just a petty bully it quickly becomes clear he is more sinister than he seems and at one point he breaks into your house to use the move Dream Eater on your character.
Dream Eater has always been one of the creepier moves on paper in the franchise and now you get to experience first hand with some music that puts Lavender Town to shame!
