1. Adam vs Zeus
I could be bias for this one cuz Adam is my favorite character from the series. The fight is intense, emotional roller coaster and Adam's death is absolute peak fiction.
2. Sasaki vs Poseidon
This was a very close choice. I could have put this fight as number 1 if it wasn't for Adam. Anyway, two of my second favorite characters fighting against each others, very enjoyable, Sasaki is goat. Poseidon is by far the best god. Love his arrogant and superior complex personality.
3. Jack the Ripper vs Heracles
Jack is by far the most developed character in the series, tragic backstory, very intelligent, unique fighting style. Heracles is ok, I wish we could see more of his other Labors that he haven't use.
4. Lu Bu vs Thor
Very hyped fight. Although I'm not a huge fan of both characters, the fight is still pretty good.
5. Raiden Tameemon vs Shiva
Raiden is a meh character but Shiva is goated. Shiva's backstory is good and his comrades trust him greatly. The fight is ok. Most people say it's shounenish but that's alright.
