Weeellllll...When I first started playing on my cousins' Xbox, I created a temporary profile named after the Iron Man villain Crimson Dynamo, partially because I kinda liked the way he looked, but it was mostly because it was the coolest sounding name I could think of at that moment. However, I guess that profile had some interactions with Xbox Live, which meant that when I got an Xbox of my own I couldn't create a profile under the same name, so I did the most creatively bankrupt thing I could do at that moment and changed it to Crimson Dynamite. I didn't like the way it sounded, so I then changed the Crimson to Envy because Envy was a shade of green (my favorite color) that sounded more dramatic than just saying green (altough upon reflection, I guess I could've gone with Jade or Emerald, but Envy is shorter than Emerald, and it sounds better than Jade Dynamite, at least in my mind).
After that, the Dynamite in my username seemed unnecessary since I'm not particularly explosive or dangerous, and the symbol stuck in my mind (which you see as my avatar) looked like a mix between a compass rose and a shuriken, I got to thinking: "Compass roses and shurikens are kind of circular, and so is the letter 'o'. Hmm...is there a cooler sounding word for 'o'? Maybe one that's in another language? Perhaps Greek?" So, through my own incredibly warped, bizarro-world logic, I came to the name: ENVY OMICRON!
