Take note that Helios Head and Zeus' Rage are not unbreakable, so your opponent is able to break those two moves if they want to. That would be less than desirable, because they lose two bars after already taking 32% unbreakable damage from B2, Apollo's Inferno.I was in the lab trying to come up with a good BNB unbreakable combo, and the best I've found is:
B2, Ex Appollo’s Bow, Helios Head, dash, Zeus Rage – 43% | (46% with jip)
1 bar of meter. Any other suggestions?
Hmm.....you can try:
B2, Apollo's Inferno, Helios Head, JIP,F+2~HDC, F+4,2(hold 2), 4 – 53% | 32% if broken after Apollo's Inferno
(Though I can't remember if it is 53 or 54% when the combo is completed)
If your opponent decides to break the combo after Inferno, they save at least 21% health for two bars, but not after already losing 32%.
