Drakien ( greek), Fafnir ( mythology), George ( English), Ryuu, Siegfried, Sigmund, Sigurd, Tatsu all mean Dragon
Slayer was harder most of these mean Kill or Killing: Voar, Vorey, Svafnir, Valr, Bana, Drepa
Hmm, where did you get that information? All those names beginning with Sig- mean victory-something. For instance http://www.behindthename.com/name/sigurd. He WAS a dragonslayer, though, slayer of the dragon Fafner/Fafnir (hence his name "Fafnesbane", where "bane" means the same thing as in English).
Magnar sounds good but Stormblade's a bit cheesy.
A couple different websites. Some on this sitehttp://www.babynamespedia.com/search/m/dragon, and http://www.vikingsofbjornstad.com/Old_Norse_Dictionary_E2N.shtm mostly. I read the Sig, names wrong... what I get for multi-tasking. my chocolate cake came out good though...lol
