The Thunder Drake.

The skies above the Grove churned with fury, swirling clouds thick with electricity casting an ominous glow over the forest. Thunder rumbled like the growl of an enraged beast, shaking the earth beneath Ethan's feet. He stood motionless, his fiery red hair dampened by the sudden onslaught of rain, as his silver eyes locked on the approaching figure.

The Thunder Drake emerged from the storm, its scales shimmering with a metallic sheen as arcs of lightning danced across its massive body. It was a monstrous creature, its serpent-like form extending over forty feet. Its eyes burned like molten gold, and jagged horns crowned its head, pulsating with electrical energy. A deep, guttural roar escaped its maw, sending shockwaves through the air and asserting its dominance over the battlefield.
