The player who reveives damage gets his BB's filled really quickly.
I came across a point where a player had Cerebella(Armed Forces) on Gold Prize Fight Mode and she had a lot of HP and Defense.
With my top tier characters I couldn't harm her at all and so she kept filling her BB's.
By the way some regulations regarding characters' upgrading stats have to be considered because if the Defense and HP is really high no one would win and we would simply run out of time.
