No sword, no arrow, no club in my hand,
But strength of sheer muscle foretold the beast's end.
Nine heads and more, the slithering beast had,
I called upon rocks to bury it dead.
The goddess felt so lonely I had to spend a year,
To capture gold and bronze on top of wounded deer.
A huge a fearless beast was trapped in a snow mound,
I caught it in my net, oh, great was my reward.
A man just got my help to clean all of his mess,
But I did gain just nought, though river I posessed.
The iron birds afly, my arrows turned them down,
A rattle as reward, they ran not to be found.
Fire in its eyes, pouring from its nose,
Throttled with bare hands, fear me, who oppose.
Eating human flesh is a monstrous thing,
Fight fire with fire, devoured was the king.
The women who fight not less than the men,
Had belt I desired so fought for it then.
Three heads or three bodies are not enough for me,
I could kill a star, so god rewarded me.
The gold, the ladies, the dragon-like guardian,
The trick, the apples, the enormous burden.
A puppy you'd call it, too many is three,
I leashed it from under to surface for free.
Replace the owner's or place's sole head
With one that is half of the journey ahead.
Agrnudgh is my name, just know my full story
Of pain and the labour and strength and the glory.
What/who am I?
NOTE Please try to explain each stanza even if you know the final answer already.
Hint (especially for those, who answered already):
The last two stanzas explain the name Agrnudgh used there. (notice the "cipher" tag)
