Just based on physical appearance:

1. This one is hard, but I think I'll go with Ray. I think Sand is more cute than hot.

2. Top. I liked Mew's look when he had glasses and thought he looked sexy in those, so I had to drop him lower since he lost them.

3. Boston. Nick is adorable, no doubt, but Boston is just hotter.

4. April! Omg, she is so hot!

My hot king is actually.....Boeing. Seriously, he came on the scene like a wrench in a cog machine and looked fine as hell doing so!
