Sasha

Sasha is an inorganic dragon and power plant. She is the size of a building, macro if you will; very friendly; and enjoys gardening. To fuel her large body, she uses nuclear power, but used to use fossil fuels. She lives in an open field and spends a lot of time making the land habitable for plants again after the damage she unintentionally caused.

Appearance
Sasha, when lying down and curled up, is the size of a wide, three-storey building (like a factory). She is bipedal and resembles a dragon. Her top 'lip' has two fang-like protrusions on either side facing downwards. She is made of concrete, but the concrete has a special additive to make it flexible. Her body is mainly a near-white grey, but her arms (except for her elbows and shoulders) are a slightly darker grey. Her body is very rigid and 'boxy', making her appear muscular. Her ears look like and act as two cooling towers. She has four horns between her ears: two vine-like front horns, each wrapping around one tower twice, and two short back horns that go straight back and curve upwards slightly at the end. Her front left and back right horns are a dark red, and the other two are black. Her tail is a hose that can release nuclear waste at will. Her pupils, inner mouth and other insides are glowing neon green. She has three digits on each hand; her left hand has three long claws, and her right hand has two claws and a black water cannon replacing the would-be middle claw. On each of her shoulders and the top right of her chest, Sasha has an atom symbol (with three orbits at equal angles from each other). Just below each of her shoulders, she has outer cooling fans.

However, Sasha's appearance looked different when she was running on fossil fuels: Her main body colour was grey, and her chest, stomach and tail were black. Her cooling towers were also black but with two red stripes going all the way around each. Her arms are red except for her elbow and shoulder which are black. Her now red horn was instead a very light grey, and she lacked the atom symbol, instead having "64" marked on each of her shoulders (and not her chest).

Biology
Instead of eating food and respiring, Sasha produces energy through nuclear fission. Sasha eats enriched uranium (sometimes in the form of cute snack bars) and drinks water for cooling her internal reactor. The radioactive waste products are expelled through her tail, and the water leaves her cooling-tower ears as steam. Water can also be expelled through her water cannon, but she mainly uses this for watering her plants.

When she ran on fossil fuels, she instead ate coal and caused a lot more environmental damage due to pollution. People protested against her very existence for damaging the climate, and she wasn't very fond of herself either. She feels happier after being upgraded to nuclear power. Her cannon also used to shoot explosive shells meant for actual destruction instead of just a stream of water.

Backstory
Sasha was created by a 'power-hungry industrialist' who wanted to create a living structure to further industrialism. She became an abandoned project after her creator was exiled and had to leave her behind. She was eventually found and powered on, standing up and crashing through the ceiling. She went off to find someplace that had more space for her: an open field, which soon became more of a wasteland. Today, she still calls the area her home, but now that she doesn't produce as much pollution, she's able to help the plants regrow. Sasha has taken on the label "structure creature" to describe herself, embracing her identity as both a dragon and a power plant.
