Guy unleashes his deadliest gate at the cost of his own life, tearing through Madara's body with dragon-like force and speed, before Naruto arrives to shield the fallen master and step forward carrying a newfound power.
Sensing his foe's dwindling chakra, Madara judges that Guy's incoming blow will be his final one. As Naruto and Sasuke stir and ready themselves to rejoin the fight, Lee and Gaara look on at the brutal duel. Guy's body ignites and pours out an enormous aura shaped like a dragon, thrilling the Ten-Tails' jinchūriki until Guy's blinding speed and space-warping motion leave him stunned in the middle of a counter.
A single tremendous kick shatters the left half of Madara's upper body, nearly finishing him and punching a gaping hole through the Ten-Tails' tree form. The effort ravages Guy from within as the vital point above his heart fades and his body starts breaking down. Madara answers by hurling a black orb meant to claim Guy's life, but Naruto appears out of nowhere and boots it back at him.
