(I will be a hypocrite and make this about cloning) I cloned one more before you stab uberchu so you stabbed the clone!!
I seal Uberchu into an electric proof box, then wrap the box in chains, then put it into a bigger box which is made from lead and replace all oxygen with poison gas. Then I bury the box under the sand in the deepest ocean. He can't float. He is underwater (no way to get out). I've checked there are no clones. He's locked, how will he get out?
