European fighters all lose
Japanese fighters will all win
The author is such a hack
Let's summarize the fights thus far (
strikeout = defeat):
Lü Bu (Chinese) | Thor (Norse) |
Adam (Hebrew) | Zeus (Greek) |
Kojiro Sasaki (Japanese) | Poseidon (Greek) |
Jack the Ripper (British) | Heracles (Greek) |
Raiden Tameemon (Japanese) | Shiva (Indian) |
Buddha (Indian) | Bishamonten (Japanese) |
Qin Shi Huang (Chinese) | Hades (Greek) |
Nikola Tesla (Serbian) | Beelzebub (Hebrew) |
Leonidas (Greek) | Apollo (Greek) |
As for the statistics.
I'll assume Hebrews are European (I'm not too sure about that classification, but I have to choose either or)
European defeats:
European fighters account for 67% of all defeats (6/9), 60% for humans (3/5), and 75% for Gods (3/4).
Of all European fighters, 55% lost (6/11), 75% of European humans lost (3/4), and 43% of European Gods lost (3/7).
It is worth noting that 44% of all fights were European vs European (4/9), where a European loss was the only possible outcome. This means 67% of all European defeats were at the hands of other Europeans (4/6).
Out of all participants, 61% were European (11/18), 44% for humans (4/9), 78% for Gods (7/9).
While the majority of losses can be attributed to Europeans, they also contributed to the majority of fighters.
Japanese victories:
Japanese fighters account for 11% of all victories (1/9), 25% for humans (1/4), and 0% for Gods (0/5).
Of all Japanese fighters, 33% won (1/3), 50% of Japanese humans won (1/2), and 0% of Japanese Gods won (0/1).
It is worth noting that 0% of all fights were Japanese vs Japanese (0/9), so all Japanese fighters could've theoretically won (but they didn't).
Out of all participants, 17% were Japanese (3/18), 22% for humans (2/9), 11% for Gods (1/9).
The Japanese contributed very little to the fights, and even less to the victories.
Asian victories (under the mistaken assumption that "Asians are all Japanese"):
Asian fighters account for 44% of all victories (4/9), 75% for humans (3/4), 20% for Gods (1/5).
Of all Asian fighters, 57% won (4/7), 60% of Asian humans won (3/5), and 50% of Asian Gods won (1/2).
It is worth noting that 22% of all fights were Asian vs Asian (2/9), where an Asian victory was the only possible outcome. This means 50% of all Asian victories were against other Asians (2/4).
Out of all participants, 39% were Asian (7/18), 56% for humans (5/9), 22% for Gods (2/9).
While the majority of human victories are thanks to Asians, most of the human fighters were Asians.
Conclusion:
Your claim would be true if it were "Most European fighters lose" and "Most Asian
human fighters win".
But let's not forget that the majority of fights were European vs European or Asian vs Asian (6/9).
If we ignore these fights, Europeans lost 67% of their fights against Asians (2/3). While the percentage may seem high, the low sample size means that a single additional victory would equalize the score. So there is no real bias towards Asians or Europeans in terms of victories and defeats.
Thus your claim is simply wrong by any possible metric I can think of. But I'm sure there exists a way to interpret your claim in which it isn't
completely wrong.
