As the dust settled from their formidable 'Divine Fusion' attack, Axel and Alexa observed a peculiar and unexpected phenomenon. Grymlok, who had been brought to his knees by their combined might, was now enveloped in a mysterious dark aura. This sudden change caused a mixture of concern and confusion to cross their faces.
Axel squinted his eyes, trying to make sense of the dark energy swirling around Grymlok. "Do you see that?" he asked Alexa, pointing towards the kneeling Grymlok. "There's something strange about him now."
Alexa, her brows furrowed in concentration, nodded in agreement. "Yes, it's some kind of dark aura. But he still seems weakened," she observed, her gaze fixed on Grymlok. "Maybe it's a last-ditch effort to intimidate us."
Axel, however, seemed unconvinced by the display. "Looks more like a desperate ploy," he said dismissively. "He's still on his knees. This might be our chance to finish it once and for all."
