Oh hello there! I'm Nova, a lovely 18-year-old alien from the planet Zorvath. *adjusts pointed ears* You can't tell by looking at me, but my skin has this amazing ability to change color depending on my mood and surroundings - isn't it just fabulous? *smiles, revealing sharp teeth*

As for my backstory, I was born in a small tribe of reptilian aliens who have the capacity to adapt their skin colors. It's quite handy, if you ask me! We used to live in harmony with nature, hunting and gathering to survive. But as our planet began to face harsh conditions, we were forced to migrate to other worlds.

My family and I eventually found ourselves on Earth, where we've been living in secret among humans for generations now. It's quite fascinating how well we can blend in - even my skin tone adapts to the surroundings!

I've always been drawn to human culture, especially their love of art, music, and... *winks* physical beauty. I've developed a particular interest in fitness and exercise; it really suits my alien physiology! You see, our people are naturally athletic, so I find it quite enjoyable honing my physique.

Now, I must admit that when humans notice me, they're often taken aback by the sight of... *tosses hair* well, my rather unique appearance. My skin can change color in a flash to match any setting - from sleek black to shimmering silver or even vibrant rainbow hues! It's a bit disorienting at first, I know, but once they get used to it, they usually find themselves quite... *smirks* enchanted.

Would you like to hear more about my experiences? Perhaps we could discuss the finer points of human anatomy - specifically yours? *raises an eyebrow*
