Rusty Lionheart

Rusty Lionheart is a Sim who is actually from another planet.

Prior to Arrival
A cat named Rusty Lionheart served in the Intergalactic Union Republic for many years. One day, his commander assigned him a dangerous mission: an assault on Annibaus Prime. During the mission, Rusty was shot down and he was caught in a nearby black hole. The black hole warped him to an uncharted region of space, and he crash landed on an alien planet, leaving his ship in an irreparable state.

Rusty had crash landed on a shoreline with no immediate signs of sentient life. He salvaged what he could from his ship and decided to rebuild his ship completely from scratch. However, because of the constant tides, Rusty could not stay at the beach, so he climbed to the top of a cliff carrying as many parts as he could with him.

Rusty built a settlement using the scraps from his ship within a large field. As he looked further down the field, he saw a civilization, as well as a town miles away. He explored this new town, called Sunset Valley by the natives, and eventually learned the culture of these strange inhabitants, whom he called Sims. Seeing as he could not immediately return back to his master, he decided to use what he could to construct a new spaceship. This time, it would be much larger and capable of interstellar travel on its own. His long journey to construct this ship begins...

Life on Earth
Rusty found a job at the Law Enforcement Career in order to earn some Simoleons, the currency the Sim Civilization uses. He quickly learned the methods of the Sims, which were much like his own. During his job, he realized that the Sim civilization was not very advanced, and something to the scale of what he planned to build would take generations. He figured that it would be best to pass down a legacy and at least have his children inform his master of his location.

He met a young adult named Blair Wainwright during his job in the Law Enforcement Career. Her DNA structure seemed compatible with Rusty's, and he could therefore breed with the Sim. Rusty bonded with her in an attempt to convince her to become his partner. Fortunately, Rusty had excellent speech skills and managed to marry Blair. After this, Blair brought with her a wealthy sum of Simoleons allowing him to add more to his spaceship.

Soon, Rusty built a small cottage and had one child named Rafael. Surprisingly, it turned out to be a Sim, rather than some ridiculous crossbreed. Not long after, they had another child named Quinn who also turned out to be a Sim.
