#2 Samoan Heritage
Roman Reigns is a member of the A'noai family, a clan of Samoan heritage who also boast some famous wrestlers besides the Big Dog. The Rock, Nia Jax, the Usos, Umaga, and Rosie were just a few of the wrestlers who have been part of the family dynasty.
While his cousin the Rock also represented the Samoan People, Roman is the one who has made it much more a part of his character and persona.
The "Island Boys" as they are sometimes referred to by themselves have been a part of wrestling almost since its inception. The Headshrinkers, the Islanders, the Samoan Swat Team and High Chief Peter Maivia are legendary in the sport for good reason. The Samoans bring a lot of power, perseverance, and attitude to their role as sports entertainers.
Roman Reigns represents not only the Samoan People but the A'noai clan as well. So when he delivers a promo or a Superman punch, he's speaking and striking with the cumulative voice of a traditionally oppressed people.
