The fandom still largely does not understand what Dark is. It IS commonly understood that "this creature uses underhanded tactics to win" is a theme that cleanly applies to 95% of Dark Types, but that also isn't the full story. Sit down and I'll school you.
Dark Type is a sort of negative energy Type, it's based on a conglomeration of oriental superstition and philosophical thinking. It's VERY common over there for people to think unluckiness or suffering is a direct result of "negative energy". When you break your leg, that happened because your body had too much negative energy, due most likely to your own actions. When an otherwise good person appears to do something wicked, it's because his negative energy built up too much. People in Asia/Japan historically really thought this was a universal FORCE, like gravity. Bad things happen when things are not "in balance". Dark Types are am extrapolation of this superstitious thinking.
Nearly if not all the 18 Types have innate "superpowers" or magic powers that are common amongst them and easy to pick out. Electrics generate electricity, Fighting have super-muscles or are unusually gifted in physical combat, and so on. Even Dragon Types have a sort of arcane energy thing going on where their "superpower" is being filled with abundant magical life energy that makes them grow huge and formiddable and have long lifespans etc. Dark Types DO have a superpower despite not seeming to have one. They all have an affinity for negative energy like Water Types do for water.
