this depends on circumstances imo.....
if its freddy CM then BA every time..............
if captain marvel is sharing his power then BA takes it every time.....
if BA is sharing his power then CM...................
if both are sharing there power(with one other person each) then it's a tie.................
if Black Adam is fully enraged and Cap does not want to kill then it's 6/10 BA(and vise versa CM wins)........
if it's both P'Oed then a tie............
and if it's both at full power then it's a tie.................
