Combination by the Skin of Our Teeth

Synopsis

They finally defeat Gokuark and save Earth from the Great Demon World. Believing the job is done, the three hand their Ganbar Bracelets and Commanders back to Gon. Kotaro is a little bummed about losing his superpowers. But the fight isn't over. Yaminorius absorbs the remnants of Gokuark's soul and powers up. He turns fireworks into the super demon beast Dokan, which blasts buildings and houses into the sky like bottle rockets. Kotaro and the rest borrow their bracelets back from Gon and return to being secret heroes.
