I'm running a super powers (anime style) campaign with friends, we've just begun and we want to keep the anime "vibe" alive for as long as we can, since Japanese Animation shows make use of several villians with diferent goals, and also introduce a LARGE supporting cast on the way.
I have introduced villian groups on my game, however tho they seemed nice at the begning, I don't know how to tie everything.
The players are all teen demigods, the game is based on the Scion RPG, using Savage Worlds as our to-go system. They have to stop the Titans from reviving by stoppeing the monsters they spawn on earth and dealing with the other villian groups. Which are:
Outer Gods: I have no idea why I even introduced them, they're supposed to be the most dangerous baddies, they want to make the Titans escape so they can use the chaos to conquer the universe but really, they're just boring, I just don't feel like I can cut them from the plot out of the blue.
Sapientes Gladio: A group of young women with the power of angels that want to kill demigods because they're supposed to be heretic. The most interesting group as a PC has a romance with one of them and she doesn't knows he's a demigod.
Shinsegumi: A bunch of over powered demigods leadered by a japanese schoolgirl with the powers of a Titan + a God who want to release the other Titans, and they are the main pain in the butt of the story; they're loved and hated by my players but I have no idea how they fit in or what I'm supposed to do with them.
13th Batallion: A group of american soldiers with hi-tech weapons built to erradicate the demigods since they're supposed to be too dangerous to exist.
And there, I have different villian organizations that are liked by my players, but I just can't seem to deal with all of them, specially since the supporting cast is comprised of almost 16 NPCs that are already loved by my players, and by me. I just don't know how to tie stuff without making plot points suddenly dissapear.
