Adrien's bodyguard is a serious, grim, and stoic man who never talks or express any emotions. He takes his job very seriously and is quite protective of Adrien, threatening Simon Grimault when the latter just wanted to shake hands with Adrien. His suspicious nature also thrives outside of his job as he glances at Marinette from a distance because she is talking back to her purse, where Tikki is, in "Guitar Villain". He isn't afraid to stand up to what he considers dangerous to himself or others, like Simon Says and Darkblade, but he becomes fearful in particular cases he is endangered. While not openly genial, the bodyguard obeys his boss Gabriel and Nathalie. He follows through on requests on others, such as delivering Marinette's Christmas gift to Adrien in "Santa Claws".
Underneath Adrien's bodyguard's intimidating exterior, he is shown to be gentle and kind as briefly played with action figure dolls and secretly allowed Adrien's friends into the Agreste mansion in "Party Crasher". He can also be easily moved as seen in "Reflekdoll", when he sees the girls sincerely beg him to allow Adrien to have fun with them.
