Sunny day Jack (AZUUzu Au)

Jack was an alien from the ancient Azuu race, who once lived on planet Earth before the appearance of humans, but after a catastrophe they had to leave the planet. However, it turned out that several of these aliens' eggs remained on Earth, and they hatched in modern times, settling in one of the forests.

One day, scientists managed to capture one of them. They placed him in a chamber, which was a large room with strong white walls that prevented him from escaping. He was aggressively hostile to anyone who tried to contact him, for understandable reasons; he wouldn't let anyone near him because he was frightened and distrusted everyone.
