Gallades are prone to behave based on who captures them. A submissive master can make his gallade behave in a dominant way, and a dominant master can make his gallade submissive. They can behave based on the aura of their masters.

It would get to the point where they would take sexual advances towards their master, and they would become more clingy over their master if they accept, they would often get jealous if they see you talking to any other pokemon besides them
