Geyser

The Leonel of the past might have really been surprised by this turn of events. In the world he was used to, even if people held such greed in their hearts, they wouldn't display it so openly. But, after his run-in with Thunderous Clap, he had already come to accept it. This was his new world now. 

"I will be taking this Beast Crystal as it's useful to me. I'll also be taking a few of its scales and meat as well, but with a beast of this size, there's more than enough to go around for us all."

Leonel said words he was planning on saying anyway before King of Seas spoke. If he really wanted to slight these people, he could easily take the entire beast into his Segmented Cube. With his strength and means, would any of them even be capable of stopping him from doing so? 

The fact he hadn't was already an act of kindness.
