tbf on the fang and Waka, Ohma didn't really seem like much of a threat beforehand. Remember that he was seeing Nikos ghosts constantly, while also being nerfed until he regained all of his techniques and memories. The fang is very arrogant yes, but he had the right to be at that moment in time.
I agree with you tho. That moment when he bodied Raian was beastly, the moment they all realise who tf they contending with is beastly, and so was the fight between fang vs Goalang.
Basically anytime the fang was getting pressed hard was super beastly.
