It's any% NG+, reapermon isn't available with a new instance of the game. Haven't watched other replays tho'

If you start a fresh file of the game then there is no mega level digimon available, at all.

Considering this any% is pretty much any% NG+ and any% (rookie) the real any% because you have to choose a digimon which is available from the beginning.

Good point, but I don't think these category names are appropriate because NG+ might be confusing on this game, because there isn't much that you can unlock anyway. But any% (mega) and any% (rookie) describes the categories quite well.

My opionion though.

P.S. welcome to Digimon Rumble Arena
