Mortimer Goth is a sim featured as a supporting character in A Sim's Tale series. He is the only child of Sunset Valley's co-founder Gunther Goth and his wife, Cornelia.
Mortimer first introduced in Book 1 as an antagonist and enemy of Leona Redfield for the first half of the story, but later became a main supporting character until the end. He also once again a supporting character in Book 2 and a minor character in Book 3.
In Book 2, he started a romantic relationship with Bella Bachelor.
Mortimer was first seen sitting alone at the corner of the cafeteria. Jean could see that Mortimer was very lonely. Bella approached and asked him to join her and introduced the Redfield twins to him. However, he act coldly towards them which led into his antagonistic relationship with Leona.
Later, during his family's feast party, Mortimer went into a fight with Leona. Both yelled at each other until they stopped by Mortimer's father, Gunther, who scolded him in front of everyone.
However, thanks to Bella's advice, two months later, Mortimer decided to made peace with everyone, especially with Leona. He admitted the only thing he wanted was "friends". Feeling sympathetic towards him, the kids promptly forgive him, including Leona.
Following the arrest of Nancy Landgraab, Malcolm absent from the school for weeks. Mortimer with Alex and Miraj made a visit, but Malcom didn't want to meet everyone.
After Jean's suggestion, he and the others decided to visit him once again together.
It was revealed that Mortimer and Bella finally became a couple. They even had their first kiss on their first date.
Mortimer was asked by his mother, Cornelia, to took a package which Katrina Caliente promised to her. Mortimer arrived at Caliente house, only to be seduced by the Caliente sisters, Nina and Dina, creeped him out. Fortunately, he was "saved" after Katrina arrived and gave him the package. He promptly left the Caliente House and returned to his manor.
Mortimer later was seen hanging out with Alex and unwittingly overheard Nina Caliente's conversation about her relationship with Malcolm. When Alex cursing Nina, Mortimer scolded Alex for his language.
Mortimer then informed about Jean's return and attended her homecoming party.
Later, Mortimer and Bella selected to became committees for an upcoming prom.
At the day when Curtiz family moved out, Mortimer and his family were present to bid farewell to the Curtiz.
Four years later, Mortimer enrolled in Sim State University along with Malcolm Landgraab. He was also still in relationship with Bella. During these years, Mortimer grown mustache (mirroring how his Original Counterpart looked like).
During the semester break, Mortimer and Malcolm decided to return to Sunset Valley.
- I was planning to made Mortimer as Jean's romantic interest, however, I dropped the idea and made Alex Curtiz instead.
- I made Chapter 7 of Book 2 as a tribute for The Sims 2 where he developed a romantic relationship with Dina Caliente.
