M4A1 is the leader of the AR-Team, but lacks experience. Therefore, she is often described as a rather unreliable T-Doll lacking in decisiveness. M4A1 has a tendency for self-blame and second-guessing herself because she was told she is more important than other T-Doll since her creation. Her insecurity lead her to putting much less importance on her own life than others do, especially her team members. In simulated instances where she was separated from AR Team's protection, she chose to die in a dignified fight to save her allies instead of putting them in danger to save her.
