Pokemon: My Name Is Damian, Pleased to Meet You

[Legendary Pokemon raising power fantasy + starts in Sinnoh + emotional bonds with Pokemon + long series + System + a young Legendary Pokemon (note: still in its juvenile stage, not fully grown, and raised by the protagonist) + god-tier Trainer + Mei as the sole female lead + travel + everyday growth + original main plot + Legendary Pokemon instance arcs + Pokemon battles + Galarian dog-abuser Leon]

My name is Damian. In a later era, I transmigrated here by accident after an aviation disaster. Since I'm here, I might as well make the best of it. I had no ties holding me back in my old life, so coming to a world I love might not be such a bad thing.

By the way, Tobias is my uncle, and he's really strong. My goal is to surpass him...

System: “Arceus, he's with me. Surely it isn't too much to let him have a Legendary Pokemon?”

Arceus: “Just don't cause too much trouble.”

System: “You got it!”
