Tarrasque

Spawned from the Prime Material Plane
Sent to punish nature entire
The reptilian destroyer has been sent
By the Gods to end this world
He is a scaled biped
A true killing machine
With two horns upon his head and a lashing tail

He has claws akin to steel
And a reflective carapace
He'll trample the weak under and foot
His name is the Tarrasque
He sends fear throughout the valley
Though dormant half the turn
He arises to annihilate the ancient ways of old

His chest shall wield 100 gems and his body 10 magic shields
His scales are like pure rock forged from the deepest Abyss

Immunity to the heat and cold
The weak shall paralyse with fear

He devours from endless miles around
No shadows from his sight
Enshrouded in mystery
A hideous abomination of God
From the Elemental Princes of Evil
A gift of no return
