Ava Cadavra

Ava Cadavra is an Urb from The Urbz: Sims in the City, who works as a cashier. She also moved to Strangetown during the events of The Sims 2 for Game Boy Advance and for Nintendo DS.

The Urbz: Sims in the City (handheld)
Ava's sprite character made her first appearance in the handheld version of The Urbz: Sims in the City, where she serves as a cashier in Phoebe Twiddle's shop. However, unlike her appearance in The Sims 2, she has short purple hair, and is wearing a white tank top instead of a black coat. She cannot be interacted with at that time.

The Sims 2 (Nintendo DS)
Years later, Ava has moved in to Strangetown, in search of "history." She demands to stay in the Penthouse and is the second antagonist in the game.

She commands the player's Sim to build a cave where she tricks people into worshiping a statue of the Prime Heifer. She also demands the player's Sim to get her a mystic cowbell and a tube of "rotting eggplant" lipstick. She tries to bring the Prime Heifer into the physical world, but, after listening to Horus Menhoset IX, the player's Sim destroys the statue, which causes Ava to furiously leave the hotel and set the Penthouse on fire.

The Sims 2 (GBA)
After the events of the previous game, Ava is now a homeless Townie during the story. Like other Townies, at the beginning of the game, she is unaware of the fact that the area that they live in is part of a TV series and that they are being filmed. She can be found in the Gothic Garden.

According to her bio, she used to be a drummer for a band called The Germinators. Her favourite TV show is "Chaz Dastard's Intergalactic Star Safari" starring Kent Hackett.

Trivia

 * Both she and her boss, Phoebe, had their debut appearances as shopkeepers who had no major role in the game, but later became interactable characters in the subsequent appearance.
 * Ava Cadavra is possibly based on the Aramaic עַבְדָא כְּדַברָא, avda kedavra, meaning "what was said has been done." This phrase is also the origin of abracadabra.
