Aiden is Lifesimmer's definition of a "bad boy". Once a needy child, Aiden has developed into a musician with an attitude and an aloof nature. Lifesimmer has described him as somebody who would tell you to "F*** off", because "that's Aiden".
Aiden Santiago was born to Penelope and Zane Santiago in Part 12. He received the Easily Impressed and Neurotic traits. Aiden aged up into a Toddler between Parts 17 and 18. He was often a source of annoyance to the Santiagos as he was such a whiny kid; however, this simply may have been due to the fact that everyone disregarded his needs. Aiden aged up into a Child in Part 23, and gained the Technophobe trait due to his difficult upbringing.
Aiden appears alongside his parents and siblings, sans Kendra, in Maple Cove. He joins the Music career and begins to pursue his interest in the Guitar skill. Aiden will usually wake up halfway through the day and go out at night.
- Aiden is named after the character of the same name from Beyond Two Souls, only his name is pronounced differently.
- Aiden's appearance is very similar to that of Tucker Martinez from diamonddx's Anon. This is because Lifesimmer based his father, Zane, on Tucker.
- Aiden appears in a Season 3 teaser alongside Lindy. The teaser promoted the idea of Aiden moving to Bridgeport to pursue music which may still happen in future.
- Aiden inherited his grandfather's hair color, like most of his siblings.
