Sure, that's why the SF and its characters have aided Raiden in saving Erarhrealm for years and succeded, as of the last game.

Black Dragon and its members have done literally nothing since MK1. They're the ones overstaying their welcome, as well as the purposeless lackeys like Reptile, Baraka, etc.

It wouldn't be so bad if they had some interesting members, Kabal is the only member I like and he isn't even a member anymore, so until they do something or have some more interesting characters ill go with yes, they have lol.

No, a couple of chosen warriors that happened to be from the SF had a somewhat relevant role in MK, and, going by your logic, the White Lotus was the one who ultimately succeeded. Furthermore, The Black Dragon also had a role aiding the Outworld Empire.

They are mostly relevant in relation to each other, his cat and mouse game is tired as hell and needs some serious development and creative writing. I do agree with you about the purposeless lackeys though.

Besides Kabal and Kano, the Black Dragon members are bleh

Im the Biggest Kano fan there is! And even I admit the Black Dragon has just been a name for for quite some time. W know very little about the BD except that they broke away from the Red Dragon bc they were Outsiders that didnt agree with how the RD was operating. Then everyone was just about killed or incarcerated with Kano being the only "Member" left.

MKX would be a great time for them to give the BD more substance/depth even.
The only reason why I believe it is a Faction in the game is bc its been around since day 1!
