Can You Get Rid Of Pokemon In Skyblock?

I have a Pokemon I don't want in Skyblock. I tried just about everything from throwing it off the edge. To jumping off my island. But can't find a way to get rid of it. So I was just wondering if there was a way to get rid of Pokemon you don't want.

 

You have two options, other than deleting your island of course You can pretty much just put it in a chest and leave it there forever, OR you can sell it to someone for a bit cheaper than you bought it for, that way people will but it from you instead of the shop
