Good question...
I actually don't know where "Flios" came from. The only thing I remember is that one of my elementary school friends was playing around and coming up with fake words. "Fleos" was one of them, and for some reason, it just made something click in my head. It just sounded... cool, so I changed the e to an i and now it's my pen name. People read Flios as Filos sometimes though... 
My actual pen name is a name from a yearbook i found in a free bin outside of a used bookshop nearly ten years ago. Most of my life I never went by my actual name anyway because its long and complicated and never sounded like my name outside of the mouths of Spanish speakers. I always found it hard to respond to because I would never listen for that pronunciation.
My pen name sounds like a real name which was important to me for my comics. I’ve been using it as my name in real life for nearly a decade. In my day job, its easy to introduce myself quickly and its very easy to google. In my hobby where I perform on stage with the name, people end up remembering me very well. I have lost count as to how many people have stopped me in public to ask “Are you _____?” I think its in large part due to the simple and easy to recall name.
My pen name is just my first name and the first letter of my last name 
I know it’s not very imaginative, but I couldn’t decide on what to choose so I just kinda settle on that. My name is kind of unusual outside my country anyway
My artistic name DarkSena I'm using was originally created back in early 2006. There was a character who's name was Sena and his story was so close to mine that I took this name as mine however... also the same year I wanted to join a forum and that name was already taken SO I was so utterly creative right 
so I had to improvise with an alternative and that's how I happened to create the name I've been using ever since
Ironically, the name RiidDisBuk (Read-Dis-Book) comes from being predictable in Smash Bros games. As in people reading me like a book.
I use the name everywhere I go on social media. And now that I am using the name to write books, people are gonna take me for a book lover. Which I am, but it's not where the name derives from if that makes sense 
My favorite camera is the Olympus Pen EE2. A half frame camera from the 1960s. The pictures look like something half remembered.
But it's really difficult these days to find one where the meter is still working so I haven't been able to use one for many years now.
I feel conflicted giving a heart to your comment.
On one hand, I like how you took a bad situation with good humor and now it's your strength.
On the other, I don't like giving a heart to the part that you had a heart problem for years.
I got my name from the planet I created called Cila which was the name of the main planet of the aliens in my first story Go Omega which was the foundation of the worlds I created.
Cila
I got the number 17 from my coach from high school who said the number 17 was the best number in the world. He had a quote on his wall that said, “The number 17 is responsible for insight, compassion and a desire for peace and love for humanity.”
Don’t know why specifically but it just stuck with me so I used the number 17.
Cila-17
My author pen name is the name of one of the first characters I wrote for a failed novel who was basically a self-insert/I-want-to-be-you character... hah... Use the name kind of as an inspiration and reminder that I can be who I want to be and not limited by the low confidence I restrict myself with.
My pen name on here is just a geometry joke because I'm a dork and it sounds kinda cool. It's a circle.... an infinite line is just a circle. I wanted to do something with circles because I think they represent my style of storytelling well. I like to have themes from the very beginning show up again at the end.
It's fair. I'm in a much better place health-wise now so my 
is behaving itself. Stark's my reminder to keep fighting.
I got my name from my ability to do stuff like this:
(I feel like Adam West Batman naming every account “Axeman Rifflord” and I just realized someone else already used the name...)
"River" comes from my Vietnamese middle name "Ha" which means "soft like a slow overflowing river" which is something Ive been trying to be more of in recent years
Stolen from a dnd character! from there i shortened to a nickname and yeah thats how im known in artist circles now lol
My pen name is MarcelotheProducer. I technically just go by Marcelo but I decided on "the Producer," aspect because I needed a username longer than just Marcelo.
I delve into all sorts of art forms, not just drawing, so "the producer" part of my name fits.
My name is Marcelo and I produce art, so the name is "MarcelotheProducer." Pretty simple but I think it's a catchy name! Lol
I used to watch ownage pranks on youtube a lot, something one of the characters used to say alot was hippity hopitus. I turned that into Hipiticus cause I liked how it sounded
I created my pen name when I was in Junior High School, so I didn't give much thought to making something that has meaning to it.
It's honestly just a combination of my name and a KPOP idol I used to like, haha! I've always wanted to change it, but people already recognized the name, so I guess I'm keeping it...
My name Mars comes of course from my love of the roman/Greek god of war, I have an oc named Mars as well and his last name Luna is the Latin name for moon, I love space. As for kitty my oc is also a Japanese cat god of fortune, whether good or bad doesn't matter. I was young when I made him and his whole family story up but maybe one day I'll write it out into a novel
