Cuphead loves his family and friends. He is very loyal to them, despite his flaws, and will do everything he can to protect them. In the beginning moments of a boss battle, Cuphead will hoist his pants, smiling, with determination on his face.

After the update, he may sometimes pump his muscles with a more determined grin.

In their success, the boys promised to never get into trouble again—until the next time. In the casino, Cuphead and Mugman were on a winning streak at the Craps table.
