Well.. i actually do thinking a lot about refrencing to the future:

Fenrir is actually
Spoiler
Show
King Furry ancestor! Who have found the seven dragon balls and wished to be king of Earth!
and on Fenrir's arc I'll also use the shape****ers

I WAS also considering to create an ancestor to Pilaf...

At a very far future from a paralell universe- Empress Burgunda! The daughter of Champa!

I have two lores which I gave a lot of thought- Trombone and the Nyagato.

About future... Hmm still a LOT can change.

Actually I thought that the RA will try to build an alternative to the empire
