Rhonder became my go-to username back at the end of middle school/start of high school when I needed a name for a MMO that I wanted to start

Prior to that I hadn't really used any one name too consistently. I had users ranging from pop culture references like "Hyper Lugia" and "Neji-san021" to "Raguna" which was the main character in the story I started writing in middle school. At the time I was starting to try and use the "Raguna" name more and more, but I found that it was semi-consistently taken on many websites already, and as well for this game. I mulled it over for a while and decided to try the name of the jerk-y anti-hero rival from my story, Rhonder, and it was available, so I went with it.
Over time as I started joining more and more websites I found that "Rhonder" was more often than not available, and so now it has become my primary username~ Nowadays if it's not available as-is for art account purposes, I just amend "_Art" onto the end, Rhonder_Art. It works well enough~
It was unintentional but it's also a partial anagram of my real name and has similar sounds, although rearranged so... I guess that's neat too? For my creative works I usually still write my real name on as the author, but like to hang out on websites with my username I guess.
