Cupid's main weakness is that he is easily duped and can be manipulated into becoming a pawn in others' schemes. He is also quite proud of his abilities as the God of Love.
This vulnerability makes him susceptible to being used by those who wish to exploit his powers for their own gain. His pride, while not strictly a weakness in combat, can cloud his judgment and lead him into precarious situations.
-
Being easily manipulated: Cupid's naiveté and inexperience make him a prime target for manipulation. Those aware of this weakness can use deception to control his actions.
-
Overconfidence: Cupid's pride in his abilities can lead to underestimating opponents and making poor decisions in conflict or schemes.
The reference material specifically states: "Weaknesses: Easily duped to be a pawn in other people's games. Also very proud of his skills as God of Love." This highlights his susceptibility to manipulation and his potential for flawed judgment due to overconfidence.
