The Agents of PSI
Mastermind is highly trained in shielding her mind, but besides this she is an accomplished telepath and capable of low-level mind control. It’s through this she sends messages to her field agents, hijacking the mind of some nearby stranger and using him as a mouthpiece.
Mastermind is also trained in memory deletion.
Regina Richards, alias MASTERMIND, is a stern-faced woman who does administration at the Agency. She is in charge of administering and withholding information, for which reason she is extremely trained in shielding her mind.
Little is known about her personal life. She has the closest relationship with LINK, mostly because he is in charge of communications for his cell.
