Sigurd, he was kinda badass
Yeah, just a little.
Sigurd the VolsungKilled Fafnir the Dragon.
Then bathed in and drank its blood; and ate its heart. (Which made him nearly invincible, gave him the power of prophecy, and let him talk to birds.)
Gets a Valkyrie to pledge herself to/fall in love with him.
Kills a berserker who attacks him in his sleep.
Also possessed a magic sword (Gram), except this one was given out by Odin, not some chick in a pond.
For further reading, he is Siegfried in the German Nibelungenlied
Sure, he's no Heracles, but Sigurd was "just a man."
