Not likely to take orders from just anyone, Headmistress is tough as nails and ready to take it to anyone who crosses her. She was able to hold her own against the soldiers fighting to keep Bruce Banner prisoner. She was prepared to take her revenge on the Leader for his lies. She was all set to face off against Betty Banner for not telling her and her teammates, the Headshop, the Leader had already met his demise, proving Betty was only using the group to liberate her husband. However, Headmistress was kept in check by team leader, Largo, but she swore that her differences with Betty were far from over.
*Note: Since these events, the Leader has been returned to life, so it remains to be seen if the Headshop will renew their plans of vengeance.
