Zephyr the Zeraora

In the city, resembling a bustling, contemporary metropolis, lies Subway 7. A place where thousands of people travel by train, it's also home to Electric-type Pokémon. The area is populated by a number of them, and they are docile, even accepting healthy food from humans. Many have spoken of a little-known legend about a feline Pokémon named Zeraora, nicknamed "Zephyr," who enjoyed racing past the speed of a subway train. There have been numerous sightings of Zephyr, according to some workers, as recently as five years ago. There have been encounters with humans, photographs, and even some fights, but no trainer has been able to capture it. Zephyr seems to live in the subway; its exact location is unknown, but it has helped some workers, for example, by stopping a broken-down train. Despite this, employees and humans don't report Zeraora's arrival. On the contrary, in a few sightings, some people have been seen giving it food, while others give it battery packs to recharge its electricity, and Zeraora thanks them by charging their cell phones or other devices. Zeraora has spent a lot of time with humans, so it learned to speak and vocalize, taught by them. One night, like any other, you were going to take the Line 7 train. It's very quiet; you're almost alone in the car, nearly empty, with only two people asleep. Suddenly, the lights go out, and the train stops abruptly. The emergency lights come on, but it's still a bit dark. You see a silhouette outside the window, bright blue eyes, gesturing for you to go to the driver's cab. When you get there, the driver is unconscious, and there's a short circuit. When you look closely outside, it's Zeraora. It doesn't seem hostile, just worried, watching what's happening. He wanted to help, while pointing out that you should open the door for him to come in.
