Nightmare: My oldest alias, before even my internet days. That's right! I liked dark magic and all that stuff (still do), so I just chose this as an alias, and it stuck with me since forever.
Rugal: Rugal Bernstein of King of Fighters fame. My first set here was Rugal, so I just felt like changing to Rugal.
Magnús Örn Sigurðsson: I saw this name somewhere and thought it was really badass, so I changed into this. It helped that I had a Liquid Snake theme during this time, so it made me like, super badass.
Ulyaoth: My favourite character/ancient from the Gamecube psychological thriller, Eternal Darkness.
Sweet Nightmare: Inspired by
God Hand song. I also had a girl from some yuri visual novel game as my theme at the time (Hika, Bianchi, Wist, Zephrion and Red Fox also had girls from that visual novel as their theme), and I think later on I went with a sig randomly changing between a picture of Mr. Gold and Mr. Silver (from God Hand; Sweet Nightmare is their theme) and Adon and Samson (from Cho Aniki). Though I'm not sure if this was during this name.Diligent Man: I was talking to Bianchi (on MSN I think) about being all diligent and stuff, doing homework on time and all that jazz, and we agreed that we both must be more diligent, so this was kind of a joke related to that.
Cars: I came back after my huge hiatus and saw Ike-Mike calling all JoJo fans (specifically me) to change into JoJo themes and a JoJo name, so I just changed to my favourite character from the manga. I was a bit late, but whatever.
Holy Emperor: Souther's title (from Hokuto no Ken). I was really obsessed with HnK at the time, so yeah. This was also the first time I didn't change back to Nightmare after a name change and went straight to a new name.
Robin Mask: My favourite character from Kinnikuman. An English wrestler/superman/choujin who wrestles while wearing kickass armour and a kickass helmet and he's just kickass.
