"You've been naughty, haven't you?!"

Director Maria Hill is the leader of S.H.I.E.L.D. She's probably very cranky.

Fiction

Director Hill observed the conflict between Latveria and Symkaria spurred by Megatron and the Decepticons, and worked in conjunction with the Avengers. Man and Machine, Part One

Maria Hill's presence in New Avengers/Transformers is due to the then-concurrent status quo in Marvel Comics where Nick Fury was ousted as leader of S.H.I.E.L.D and replaced with Hill. Her full name is not mentioned in the miniseries, her only being referred to as "Director Hill".
Maria Hill has been voiced by Transformers alumni Kari Wahlgren and Tabitha St. Germain.
