Here is a ref of Lucia. As always, this took me a while to do.
I like how I drew her back side xD
I redesigned her a tiny bit, like her gloves, but it's not a big deal.
I hope you find this helpful.

Name: Lucia
Species: sheep (computer/robot)
Sex: ewe (female sheep)
Weight: A bit heavy, since she is made of metal (you can't really tell, her design is very sleek, not rough and rusty looking)
Age: 150 years old
Created: June 3rd, 3087
Family: her creator, who is dead, and her current master Venice.
Residence: She doesn't have one. She travels around the world (likes to fly)
Job: she guards these nuclear weapons from falling to anyone's hands (good and bad hands) in a dark underground laboratory.
Likes: Being outside, nature, animals, flying, outer space.
Dislikes: Violence, weapons (especially the ones she is guarding) mean people.
Abilities: flying since she has those boosters under her feet, turning her arms into anything, like a gun, blaster gun, machine gun, and a chainsaw (rarely uses chainsaw though)
Personality: shy, very curious, innocent/naive, easily bored, kind, lonely, and sometimes happy and hyper at times. She has feelings, she is a self-aware machine.

Bio

There was a horrifying nuclear war which started in the year 3084. Scientists from countries all around the world were competing, for the bigger and deadlier bomb.
These bombs destoryed a few major cities around the world, and the majority of the eastern world was dilapidated because of the terrible fear that spreaded there.
In 3085, a scientist named Prof. Laurel the Cat created the deadlist bomb ever, a bomb capable of destorying an area the size of Rhode Island. He made three of them.

He conducted a test on his creation. Laurel had a adopted daughter, a tough "Rosie the Riveter" soldier named Lucy the Sheep. The test killed his adopted daughter, who was "accidentally" locked in a warehouse, which that warehouse was the target. The person who locked Lucy in there was her "best friend", who envyed her for some reason. That girl who locked Lucy in there was eventually caught, and sentenced to a forced labor camp for 30 years.

Laurel was so devastated of his daughter's death, that he swore to end the creation of nuclear weapons. He did so in 3087, by creating a computer/robot named Lucia.
Lucia was programmed to guard the remaining weapons he created, since they cannot be dismantled.

The government eventually found out, and shot Laurel, and then came for Lucia, determined to disactivate her.
Lucia, saddened, and furious at the government agents who shot him. She killed all of them, by chopping off their heads with a chainsaw (the first, and last time she used one) when they were ready to attack her in her laboratory.

Afterwards, she locks herself inside the lab for 140 years, never seeing the light of the day.
How she was released into the daylight, and what happened to the weapons is a mystery, even to her, since part of her memory was destoryed (probably from a fight from another machine who might of discovered, and invaded her eerie dark lab.

<sub>Idk, you can crit if you want, I don't really care, just a ref.
