While the Games themselves are a major obstacle, President Snow is the mastermind behind them and the driving force of the oppressive Capitol regime. He is the ultimate source of the fear and control that defines the lives of the citizens in Panem.
Here's why he's considered the main antagonist:
* He orchestrates the Hunger Games: Snow created and maintains the Games, which are designed to keep the districts in line and prevent rebellion.
* He is a symbol of oppression: Snow represents the Capitol's cruelty and ruthlessness.
* He is the ultimate threat: Snow's power and influence are vast, making him a constant danger to Katniss and the rebellion.
While characters like Cato and Marvel are formidable opponents within the Games, they are ultimately pawns in Snow's larger scheme. Snow is the true architect of the suffering and injustice that Katniss and the other tributes face.
