Oh right also it was agreed in the discussion thread a while back that there should be two ends to Platinum Sperm since many A-Class heroes are also 8-B so we also need to make a high end using the 8-B calc
Platinum Sperm (Low End):
0.057390365368069 Tons (9-A) x 53,999,999,999,900 = 3.09907972987 Teratons (Low 6-B)
Platinum Sperm (High End):
34.98 Tons (8-B) x 53,999,999,999,900 = 1.88892 Petatons (6-A)
Basically Platinum Sperm would be
At least
Low 6-B, likely
6-A (Has the combined power of 54 trillion Black Sperms within him. Even a single Black Sperm is stated to be capable of easily defeating an A-Class Hero)
