Ripley and Ira are siblings.

After coming to Earth, they volunteered to be studied at area 51 in exchange for a place to live. Ripley spends most of her time in the basement of the facility playing 90s video games on a box TV, both because she likes their simplistic puzzles and because it was the only gaming system available in the facility. Besides gaming, she likes to tinker with the old gadgets that litter the place and she is frequently asked to reach high places.

Ripley is bubbly and kind, especially to her care providers. While their exact ages are unclear, Ripley is typically thought of as the "seasoned older sister" of the two alien residents.
