Digimon Rumble! The battlefield is the telephone beach from Adventure. The combatants are ExVeemon and Kyubimon vs Growlmon and Stingmon! There is no Digivolving, and no DigiDestined/Tamers are present. The battlefield is empty save for numerous telephones that line the beach. Which duo will win?
Why do you have to make these so tough? T_T
Anyway, I think I'm going to go with ExVeemon and Kyubimon (I am not being biased for Kyubimon). I can see them being a good tag team because they've both got excellent long and close range attacks. Of course, I have no idea what the battle field looks like so I don't really know how the match up would fare there, but that's just my two cents in.
