I don't think that Koby is the one leading the attack because he's a Rear-Admiral. But unless it's Garp, Tsuru, or one of the admirals (which is not) Koby ain't touching Hancock, Hancock is on another level especially if she's powerful as she is in Stampede.
I said this before but I think Oda is just using Koby as a "narrative resource" in order to inform Hancock about the situation in Wano, keep my words, she'll join the war and it will be HYPE.

Kizaru, Green Bull weren't shown. While Fujitora is shown on a ship and stainless leading the fleet against Buggy.
