In the Metroid series, the main character's, who is a combat fighter like the Master, last name is Aran (Samus Aran). He also shares his name with "the Aran" of Maplestory, which also uses combos and animals as a part his fighting style.
Aran (อรัญ; meaning: forest) is one of common first names for a Thai male. A variant form, which is Hebrew, means "mountain of strength".
Aran was originally meant to be shirtless in the original game. However he was later given a shirt before release for unknown reasons.
It is hinted he is Thai, from the fact that he does kickboxing, as well as his name and appearance, but both his house blocks and his fighting style (Sim Fu; obviously based on the Chinese Kung Fu) suggest he is Chinese.
In his tasks, he only requires a Training Dummy the whole time. He also asks for essences for all six interests, with the exception to his hated interest: Cute.
In MySims Agents, it is revealed that he has a tattoo of a tiger on his back, which is the same picture as the one on the back of his shirt.
Like Shirley, he first arrives at Star Level 3, but you cannot complete his final task until Star Level 4.
