I don't see XZ or DY doing it, but...Originally Posted by CC
GJ did a roar when he was 33 at the very beggining of ROCH to try to force LMC to compete with him.
Shenshan was able to do a impressive roar.
After the 1st meeting with the 3 Du Monks, ZWJ left roaring to try to scare the monks and make them treat Xie xun better.
Not sure why JY sticked it in. Probably to show that this isn't compete BS thought from his mind. And it also shows that YG is already pretty acomplished internally.
