The Strong Brothers are the rough, tough, biker gang that everyone, including themselves, hate composed of Strong Bad, Strong Mad, and Strong Sad. Their fairytale-like names make them seem harmless at first, but they can cook up a mean pot roast. Being brothers, they obviously share many similar qualities, besides just being total eggs who ride Harleys.
When they aren't bringing chaos to Free Country, USA, they're bringing it to Everything Else. There have been numerous attempts to arrest this diabolical group, but to no avail so far, because of the fact that Strong Bad only claimed this was the truth in his The History of the World. Strong Mad and Strong Sad have both denied this.
