Scenario 1: One at a time, all bloodlusted
Scenario 2: All at once, BL
Joke Scenario : How long can he last without getting hit? He's IC, Touhou is BL.
You certainly have a reputation for making mismatches. :\
From what I know, Touhou caps off at planetary with some very broken abilities but all that means very little when considering Alphamon Ouryuken is a universal+ being with time-space manipulation, a good deal above many universal class digimon, transcends time-space, most of the lower and weaker digimon have a majority of the hax possessed by the Touhou characters and Alphamon O is leagues above them, etc. Plus, NLF in effect.
He solos. IC, he probably won't kill them but they won't be doing anything either.
