Since I've seen a few people bring up Rukodiora recently. I don't know about Ascendance, but I do think it is quite possible for it to appear in the Main Series in the future.

They can def play with his magnetism Narwa already do similar stuff to some extent

I saw the Ascendance logo, and the magnet-like colors immediately reminded me of Rukodiora. I know it's a long shot, but I really hope this monster makes a comeback in the main series.

To me the most obvious is still Akura vashimu

It does need some teeaks though

Peakodiora

To this day, I still dream of having a Paria Puria and Eviljho quest hunt 😫

I mean they have many of the Frontier Dev in the Main Game teams so i hope that over time we get more of the great Frontier monsters in the Main Games, a Guardian Version of the Scorpions would be cool or Abiorugu as new Pack Monster and it's HC Version as Alpha

I’d believe it for a late TU, maybe not for the release though
