Harry always thought that Mrs. Figg was just a batty, cat-loving neighbor on Privet Drive, but this year he learns that Mrs. Figg is actually a Squib (a non-magical person born to magical parents). She's the only person around connected to the Wizarding world when dementors attack Harry and Dudley, and her anger shows that she cares deeply for Harry's safety. She later testifies at Harry's hearing, and though Harry isn't sure how much good her testimony does—she only poorly describes what dementors look like—Harry gets off.
