I used to be a huge Pokemon fan as a kid and Manaphy was one of my favorite legendary pokemon at the time. I found out that Manaphy was used a lot so I decided to go with Phione and added baby behind it because it is actually the baby of Manaphy. I added some random numbers because the name was bank for me at that time and since then the username has stuck with me and I use the username most of the websites I joined.
So about 4 years back I went under the username xXFrostZeroXx in Minecraft (Total Weeb I am), and I realized how stupid it sounded with the "xX" So I sought out to find a better username, something that sounded better at easier.
So as I was thinking, I realized why not combine my name with something reletable to make it sound cool. My IRL name is Kyle btw.
So then I realized that in the name xXFrostZeroXx the word Zero stood out pretty well. I combined the first word of my name, Ky, and replaced the Z in zero. Ky+ero == Kyero.
About a year ago the game "Dex" was relased on Steam and I really liked the trailer so I decided to buy it. The game's protagonist's name is Dex and I thought it was a really cool name so I decided to have that as my username. After a couple of weeks I wanted an original username that could only be inspired by Dex's name so I added "enta" to is because of my entomophobia.
I've been called Elly/Ellie my whole life (typical shorter version of my first name)) I was looking up Japanese versions of names one day and wondered how mine would look , and since Ellie is always taken "Erie" came into play besides.. I think it's short and cute ^-^
