Calm and serious, Zuphlas is extremely protective to Irene and other team members, despite his natural weakness to many Pokémon types in battle. It's hard to imagine Zuphlas in a romantic way, but he indeed fell in love with a beautiful Froslass in the past, only to discover that she was only acting sweet to him because she was gentle to everyone, but she already had solid relationship with a Glalie... Even today, when the days are clear and you can see the top of Mt. Coronet, Zuphlas can look at it for hours, thinking about his old life and love there.
