Honestly, I hope Neodevimon and MagnaAngemon get their own counterpart to Mastemon

In Adventure 2020, they debuted NeoDevimon and Donedevimon as a new evolution line for Devimon, with NeoDevimon being TK's temporary partner. In the context of the show, I kinda wish they had gone further with that for TK as a character, maybe having Angemon + Devimon as a co partners or make Neodevimon+Donedevimon an alt evolution route for his Patamon that he could choose to go into.

I feel like the set up is there for MagnaAngemon + NeoDevimon to have their own jogress form down the line. Lucemon Chaos Mode could potentially work, but I feel like the two of them should have something unique to their form as well.
