It's called cauliflower ear! It's a common thing for mma fighters to have from getting hit so constantly on the ears.
The trauma causes the ear to fill up with fluid which can only be drained manually but most fighters choose not to drain it since it happens so often and they see it as a badge of honour :)

I'm too late for this but now that it has ended i still can't help but notice...
AM I THE ONLY ONE WHO THINKS THAT JAEKYUNG'S EAR IS WEIRD???!
or maybe it exist in real life but i just haven't seen one that's the same idk ╥﹏╥
