HK Harald was getting slashed up by Gaban and Shanks for a long time, mf just kept regening, but it's noted his regen factor was slowing down thanks to that before he fights Loki, as already commented by the two. He was getting stabbed and tagged by FODDER giants, ran through, that's not impressing me. Or are we ignoring this??
When Harald and Loki start the fight, yes Harald is still controlled by Imu. However, mid-fight he gains back the conciousness after he sends Loki flying, slashing him even, he stands there, and literally tells Loki to finish him before Imu takes over. Why? Cause once Imu takes over, Loki ain't doing jackshit, none of them bums are. lol
This fight is basically Luffy vs Kizaru, Loki fans being the Luffy fans in this case.
