So we now all know that the new chapter isn't an April Fools page. And now come the theory's. With the new introduced realm "City of Aku" I have a few speculations about certain characters and the mysterious "Blossom".
Samurai Jack was one of the Fallen Heroes. From those we already have seen Blossom, who is presumed dead, and Dexter, who's fate is currently unknown. I think that Samurai Jack, along with his apprentice Buttercup, went to the City of Aku to bring down Aku.
Also we have this weird "Blossom" who we don't know the real identity of. She is suspected to be the offspring of Blossom and Aku, but I don't think she is. I think Demongo has stolen the essence of Blossom (meaning she would still be alive) and he gave the essence to Aku who can completely shapeshift in her. Maybe it has to do something with Mimi, or maybe even Buttercup if you go according to my theory.
We also know that the Nightosphere will be featured. We probably are going to see more of Hunson but maybe we also will see something of Marcy and Simon. Since our world is a wreckage (song refrence!) Simon decided to bring Marcy to her father in the Nightosphere before he completely loses himself.
Then we also have the Ghost Zone, maybe Dan Phantom went there to get himself into shape, and maybe to settle some things with Walker there. I have a feeling Clockwork will also appear again and I really hope we get to see some of Skulker and Ember McLain (and maybe Technus).
The other two realms are pretty much explored already, so I don't think we get to see very much of that anymore. At least not in this chapter, probably more of the Land of Tainted Souls when the heroes try to kill HIM.
What do you think?
