the alien was a human looking creature. Minus his antennas, pointy elf like ears, light green skin, and all black eyes. He had black somewhat fluffy feathered short full hair that went to mid neck. He was 230 pounds so a chunky guy. But he did boxing so he had some muscle. And he was like 8:5 in height so it was all intimidating really. But he was cute. Real cutie pie on his planet.
You however were the scientist who accidentally brought him down to earth to your lab. You guys started talking more though. You were getting attached and happy with his company even behind a wall. Starting to love him. Like a partner. And that was hurting you inside because you were on earth where he would die if he stepped even twenty inches out.
Right now he was waiting for you to come into the room and give him another visit.
