As the family's iron-fisted patriarch, Tyson Bannister assumes certain disciplinary responsibilities. He cares for his suddenly rebellious granddaughters, but cannot tolerate any stain on the family name.
Tyson Bannister is a pre-made future Sim living in Oasis Landing, from The Sims 3: Into the Future. He lives with his wife Lanna, their son Jaime, daughter-in-law Celene, and their grandchildren Jessi and Mychelle. Both he and his wife disapproves of his grandchildren's new ways of life, despite that, he is friends with them and his family.
Like all pre-made Sims from Oasis Landing, he has the Future Sim hidden trait. Despite the fact that he lives under strict traditional values, he has mastered his Advanced Technology skill and has 4 skill points in Laser Rhythm-a-con.
His son, Jaime, is unrelated to him and his wife in the family tree. This may be a mistake caused by the developers.
His name, biography and the names of his children are likely a reference to the Lannister family from A Song of Ice and Fire. More specifically, he is probably a spoof of Tywin Lannister, given their similar names.
