The theory that Adrien Agreste from "Miraculous Ladybug" might be a Sentimonster is quite intriguing and centers around several pieces of speculative evidence within the show:
1. Creation by Emotion: Sentimonsters are beings created from emotions through the power of the Peacock Miraculous. Adrien's life, as portrayed in the series, is filled with emotional manipulation, particularly by his father, Gabriel Agreste, who is known to possess the Peacock Miraculous. This connection suggests that Adrien could have been created as a perfect son in response to Gabriel's grief over his wife's condition.
2. Lack of Background Details: Adrien's past is somewhat vague. There are very few details about his childhood, and most of what is known centers around controlled environments orchestrated by his father. This lack of a detailed history might hint that Adrien does not have a past because he was created, not born.
3. Gabriel’s Overprotectiveness: Gabriel is extremely controlling and overprotective of Adrien, more so than a typical parent. This could be because Gabriel is not just protecting his son but also a creation that is crucial to his plans or emotional state.
4. Connection to the Miraculous: Sentimonsters are connected to an amok, a magical object that sustains their existence. If Adrien were a Sentimonster, it would explain his deep connection to miraculous-related events and characters, and possibly his uncanny ability to be in the right place at the right time.
5. Emotional Resonance: Sentimonsters reflect the emotions of their creator. Adrien often displays a perfect demeanor but also deep, unresolved emotions, mirroring Gabriel’s hidden feelings.
While this theory adds an interesting layer to Adrien's character and his relationship with other characters, it's primarily based on conjecture and fan interpretations rather than concrete evidence from the show. Nevertheless, it's a fun and popular theory that adds depth to discussions about "Miraculous Ladybug" and its complex narrative.
