Throws his lightsaber in the Lylek's Queen exposed mouth, guiding it with the Force to spin rapidly

She lifted him high and jerked him toward her slashed face, the ruin of her eye, her mouth opened wide to hiss, exactly as he’d anticipated.

“Finish her!” his Master shouted.

He threw his lightsaber at her open mouth, guiding it with the Force, causing it to spin as rapidly as a rotor as it flew into her gullet. She gagged, recoiled, one good eye wide with pain and confusion, as Vader maintained his mental hold on his spinning blade, cutting her apart from the inside out. Desperately, instinctively, she drove the spiked, poisoned tip of another tentacle at his chest.

Enmeshed in the Force, he caught the spike in his gauntleted fist and stopped it before it reached his armor. He grunted with pain, with exertion, the thick, muscular appendage of the giant creature straining against his Force-fueled strength. He was the stronger, and stared into her face as his lightsaber tore through her innards and his Master’s lightning charred her flesh.
