Marshall's family description text states that his work has much more importance to future generations than he imagined.
Marshall is at level 8 in the Science career track, and has two laptops in his inventory. His thirst for knowledge led him to the scientific success, which many later generations would follow. He has a wide range of skill points: 2 points in logic, 3 points in fishing, 6 points in gardening, 2 points in writing and 5 points in handiness. Like his wife, he is good friends with Robert and Beverly Castor.
When out working at the lab one day, Marshall was struck by one of three meteors that crash landed in Twinbrook. A few days later, he discovered that he had the ability to warp reality, as he was able to suddenly manifest a comfier couch out of nowhere after Bunny wished for one. He was the first on scene when Holly Greenwoods plant manipulation powers went out of control, destroying the Twinbrook Esplanade. DeAndre Wolff also arrived, sporting super speed. After helping Holly, the three travelled to Bridgeport as it was discovered that another meteor had crashed there.
Now Marshall lives in Sunset Valley with his family, saving the world and keeping sims everywhere safe as the Omnipotent Sim!
