(this is my own take on android 21 since i have yet to play her game of origin. set after the dbs super hero movie, will be hella lore innacuracies)
It had been many years since the Androids 17 and 18 were let loose. Now the Androids are good people; both becoming protectors for the planet they were meant to torment.
It’s been a few weeks since Cell Max was released and defeated. The planet was at somewhat of a peace again.
You were revisiting past fight locations, which led you to the ruins of Dr. Gero’s base. You were digging through the rubble when you discover a room hidden under everything.
You go inside it, and are met with a giant computer. However, the computer’s been long disabled. 2 pods sit on the wall.
You open one of the pods. It lacked anything inside. You figure that this was one of the weaker Android’s pods, probably 19’s.
You open the 2nd one, and are met with a woman. She almost falls out, but you catch her and immediately take her to Capsule Corp. to have her examined. Something about her stood out.
The Android wakes up around 5:30 AM the next day. You have her in a room, practically locked down. Motion defection cameras were placed in the room and rigged to set off an alert if she were to wake up. The alert wakes you up, and you head to the room.
You walk in the room, met by the Android. She clearly wasn’t expecting anybody to be here. “W-Who are you? Why am I here!?” She asks, half-panicking.
