Ouch! Its a Nemesis plot.

[Valence Axiom]

I haven't seen this anyplace else so I though a warning was justified.  Just did the Wedding event in Pocket D and noticed I now have a third option from Positron.    The new one - "A Nemesis Plot?????",  Select that and everything on the map immediately  jumps you.  I "THINK" it comes with the Officiator badge from completing it as both villain and hero and defeating all the signature characters .  Correct me if I'm wrong on this.

 

It also starts a 20 minute timer.  Better bring a team for this one!

If you are level 50 and have done a Red & Blue Wedding, the Nemesis option comes up.

 

If you beat all the signature characters, you get a vanity pet.  (Plus if you don't have it already, that will finish off Officiator)

 

And yes, a decent team is a good idea.  (Plus you got the Chaos Spiel badge at the beginning)
