Sun Wukong and his friends face a life-or-death crisis against the unimaginable power of Wang Woo! To protect his friends, Sun Wukong casts a spell. Iron Fist! Fist, gwon 拳! Wang Woo has grown stronger with the essence of numbers and the power of his mechanical armor. Sun Wukong's group fights back with all their abilities, but they are eventually cornered by Wang Woo's overwhelming strength. Just then, Aramchi awakens a special power and discovers the energy of the number essence embedded in Wang Woo's gauntlet, revealing his weakness to everyone. Right on cue, Saion joins the battle and temporarily halts Wang Woo's attack with his nullifying ability, but the situation doesn't improve. With no time to catch their breath, as Wang Woo's final blow approaches, Sun Wukong remembers Samjang's words that gathering the essence of the Five Elements will restore his original power. He then casts the Chinese character spell he once used in the Jade Emperor's realm... "Gather the energy of nature, engrave its true meaning, and fill it with unshakable will! Come forth! Iron Fist! Fist, gwon 拳!"
