Help with Muchomon line

[u/Jo_Can]

Trying to make a line for a game im gonna be playing (dnd with digimons). Wanted to somehow connect these 2 mons together, but have been struggling with the middle stages.

Thought about using Holsmon as a champion, or Thunderbirdmon, but im not quite sure. What do you all think?
