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 tells the player to build a cave in the hotel, which she uses to worship the Prime Heifer. She also asks for a mystic cowbell and a tube of "rotting eggplant" lipstick (which can be found on a cow and in the store, respectively). She tries to bring the Prime Heifer into the physical world, but, after listening to Horus Menhoset IX, the player destroys the statue, which causes Ava to furiously leave the hotel and set the Penthouse on fire.

After completing her section of the game, she can be stay in the hotel as a guest. When checked in, she promises not to cause any more trouble.

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.
