Well, I've got an idea. 

Since a few people offered. I'll put Jean against Schradinger. As he asked.
Important, Vordak, and Skallagrim can choose which one they would like to fight. If they wish to fight in a group, or if they wish to fight different ones.
As well, Green was looking for someone too. Since he finished off the Giantess, would you be willing to fight one as well?
