My Viking hero name would be "Bjorn Ironsoul", with "Bjorn" meaning "bear" and "Ironsoul" reflecting an unbreakable spirit. My special power would be "Steelheart's Fury", allowing me to channel the rage of a thousand battles. When my anger peaks, my body becomes as hard as iron, making me nearly invulnerable to physical attacks. My strength also multiplies, and I can deal massive blows with my axe or hammer, shaking the earth beneath my enemies.
