When Max builds Markov, a miniature robot capable of real human emotions, he is hesitant to even reveal him. After helping prevent a computer virus from wiping the school's servers, Principal Damocles instead confiscates Markov, thinking that he's a toy. Separated from his friend, Markov even becomes akumatized, and Hawk Moth converts him into "Robostus", a techno-threat capable of giving life to mechanical devices. When Hawk Moth tells Robostus to bring him the Miraculouses, he mistakenly informs him of their power to grant wishes. Robostus takes Max with him in his new mega-sized body to the stadium, where he ambushes Ladybug and Cat Noir. When Robostus is about to obtain the heroic duo's Miraculouses, he intends to take them for himself to gain mortality; only for Max, wanting his friend back, to free Ladybug and Cat Noir, who capture and de-evilize Markov. Marinette later asks Master Fu, who elaborates the Miraculouses' ability to grant wishes. Due to the universe needing to maintain balance who ever is granted a wish, someone else must lose the very thing wished for. Marinette promises Fu to not allow this, and continue guarding her own Miraculous.
