Zangetsu cackles, his laugh unhinged and creepy, as he yanks on the clone's tail to knock it off its feet. It's a good thing these clones don't have Gon's steadfast belt; that would make this impossible.

He actually starts to spin in a circle, dragging the clone along as he goes. He saw this in a video game once. Super Mario something or other? There was a big spiky tortoise involved.

Zangetu spins and spins in a tight circle until he has the clone in the air with centrifugal force. When the clone is at the highest velocity that the Hollow can manage, he... lets go.

He sends the clone flying away from the prism.

And hey! If there just so happens to be another clone running this way? Well, then the collision will be all the sweeter.
