Bridget is the mother of Oliver and the main antagonist of the Arcturion Arc (the second half of the second season) of Mighty Med. She is secretly the supervillain Mr. Terror, a feared crime lord who is searching for the Arcturion, an ancient artifact that will grant her superpowers to become the most powerful villain on Earth and conquer the world.
She succeeded in manipulating Horace Diaz to fall in love with her, knowing she would die and he would resurrect her after using the Arcturian's power. Bridget was eventually defeated by her son and his two best friends Kaz and Skylar Storm and imprisoned. However if it wasn't for her the trio would have perished when Mighty Med was destroyed by Roman and Riker.
