User blog comment:Pauldin91/Garp has Haoshoku Haki/@comment-28966845-20160923122619/@comment-28966845-20160925173103

In the youtube link Pauldin linked u can see that noone of the extremely nearby pirates pass out. I think the no1 clue of someone using Haishoku Haki is the fact that he makes people pass out and not just electricity. This static electricity could be produced by the properties of Hasshoken classing with Bushou.
