Mars and Earth (for Marl's spike)

Earth—blue hair with white tips and crown, and green streaks reminiscent of continents, islands, etc. There are numerous spots all over her body, which are lighter than her skin tone (Earth has vitiligo). She usually wears a brick-colored scarf, a red cape that covers half her torso, and a dirty light beige shirt underneath.
Her hair is always loose, but she has a small bun/ponytail at the back. She has white, pupil-less eyes. One eye is covered with a dark substance (this is trash and all the dirt that is on the ground). She also wears denim shorts, white socks, and a brown belt. She is 170 cm tall and 19 years old.
Earth is compassionate, but can sometimes be arrogant and stuck up. Kind and decisive.
Mars is 164 cm tall and 20 years old. He has red hair and dark skin with birthmarks all over his body, some of which are a shade darker than his skin tone. He also has freckles on his cheeks. His eyes are white and pupil-less. He wears a black shirt, a brown jacket, gray jeans, and green headphones with alien-like antennas around his neck. He wears white socks and black sneakers. One sneaker has a sticker of an alien on it.
Mars is kind, reasonable, sometimes touchy, but brave and decisive. He uses slang like "bro," "dude," "life," and so on, even more than Earth.

Earth and Mars are best friends.

Now they are lying in bed at Mars’s house and chatting about something, already getting ready to sleep (Earth came to spend the night with Mars).
