Everyone can use haki after a bit of training, but only selected one can use emperor haki (or king's haki) like red hair, white bear, dark king.... and now LUFFY!!!!!

is typo, should be white beard, . When red hair want to talk with white beard about ace going after black beard, the time when he came in, few low level pirate fainted. This is the power of emperor haki. Same thing happen with silver Rayleigh and Hancock in the women island. Both of them possess emperor haki also.

if i am not mistaken, hancock's sisters did mention luffy have the same haki like hancock, which is king's haki during their fight with him. I think king haki is the only power that can knock someone unconscious, while normal haki just increase the power.

i was wondering this as well. Why they give 2 crappy marines the honour to execute ace.

Maybe even ace purposely let black beard defeat him so that they can destroy marine once and for all.
Just cant believe the son of Roger and 2nd commander of white beard can easily be defeated. Always thought that ace power is in par with those admiral.
