'Malcolm Landgraab moved from Sunset Valley in order to extend the reach of the Landgraab family. With good looks and a sharp wit, Malcolm has carved out a nice section of the town as his own. Now he has his eyes on the mayor's office as he grooms his son to take over the business centers in town.'
Malcolm appears in The Sims 3 as the only child of Geoffrey and Nancy Landgraab. He would presumably be an elder, or close to becoming one, by the time of The Sims 2, but he does not appear in The Sims or The Sims 2.
He lives with his parents in a large house in Sunset Valley. He is different from his parents, as he is a good, ambitious bookworm. However, he is more like his father, a family oriented doctor, than his mother, who is a snobby businesswoman. According to his mother's bio, she often neglects Malcolm because she is overly concerned with her looks, job, and social life.
In his relationship panel, Malcolm starts off with a higher relationship with his father than with his mother. Also, if his father gets promoted, he will likely get a lifetime wish to become a surgeon, but he doesn't get any related wishes if his mother gets promoted. This suggests that he aspires to be more like his father than his mother.
Although his parents are rivals with the Altos, he seems to have no current conflict with their daughter, Holly Alto.
Malcolm lives on the cliff-side of Moonlight Bay on a large lot with his wife Hannelore, and his teenaged son Adrien. The house includes a pool and many palm trees. The description of the home describe it as an 'exotic getaway'. Malcolm and his family is rich and they are presumed to own many of the businesses in and around Moonlight Bay, notably the library.
Malcolm possesses both the Snob and Good traits. Malcolm moved from Sunset Valley for a better life; and desires to provide his son, Adrien, the best for him so that Adrien may be as successful as him. Presumably following his mother as a succesful businesswoman, or following his father's own footsteps, Malcolm pursued to establish a high level in the Political career. When the game is started, Malcolm is a Local Representative and he often is the boss of the player's Sim when they join the career. Malcolm and Tyler Vasquez are co-workers
Malcolm is the son of Nancy Landgraab who, like most other Landgraabs, expects her son to inherit her family's dynasty. (His father, Geoffrey took the Landgraab name when he married Nancy.) However, he looks unhappy about the thought and obviously isn't happy about the family rivalry. The connection between this branch of the family and the one in The Sims 2: Open for Business is unspecified, but it is likely that he and Malcolm Landgraab III are contemporaries. He may be the great-nephew of Malcolm Landgraab I, the second cousin of Malcolm Landgraab II, the cousin of Malcolm Landgraab III and the second cousin of Malcolm Landgraab IV, but that is not certain. It is also possible that he is a younger version of the Malcolm Landgraab in The Sims: Bustin' Out and/or The Sims (console), and therefore the father of Mimi and Dudley Landgraab, but that is speculative.
