The Hungers Games: The Ballad of Songbirds and Snakes features the character of Tigris Snow, who appeared in the original Hunger Games series. Serving as a prequel to the first four films, The Ballad of Songbirds and Snakes centers on the early days of President Coriolanus Snow. Decades before becoming the power-hungry President of Panem, Snow was a mentor during the 10th Hunger Games, and The Ballad of Songbirds and Snakes dives into the character’s life as a teenager, in part by exploring those Snow was once close to.
