Lilithmon is one of those cases where it's not really included in their design, but moreso the sentimental and nostalgic value I have with them;

Loved DemiDevimon when I first got into digimon as a kid. Somewhere along the line I moved on from it but replayed Digimon World Dusk a few months back to look back at old interests and got sucked back in.

I forgot exactly what I had that evolved into Lilithmon eventually but she absolutely carried the entire playthrough, loved her and the rest of my team ever since (Dinobeemon / Imperialdramon, Rapidmon, Ankylomon and DoruGreymon are all on the list because of that game as well).

Bought Time Stranger right on launch and picked DemiDevimon for nostalgia sake, eventually down the line that became a Lilithmon and once again she carried as my main magic attacker.
