At this moment, I'm wondering where I got this name from.
It was like 2013, and I had a certain obsession with Pokemon and Nintendo. I tried to create a channel on YouTube using strange combinations of Japanese, until one that I liked a lot and related to the thunder, which I liked very much: Radrion. Obviously this was incomplete and I decided to put my birthday on the name: 0507, but I thought it was too long, so I reduced the number to a "557". Over time, my dream of YouTube and having Nintendo consoles (I am middle class) vanished and the "Alpha" was born, which I took thinking of a username that would be simple, attractive and disused. I looked for meanings and I said to myself: "You are a person who leads and always seeks the best not only for you, but for others, you are the Alpha of a pack". I mixed it with the legendary number 557, and that's where the "Alpha557" was born. Sorry for writing so much.
