Rivalling Wills

Madara instructs Hashirama to follow his lead and uses Fire Release: Great Fire Annihilation on Hashirama's wood dragon to make the dragon so hot it glows red and attacks their opponent. Once the opponent is pinned down, Hashirama uses Wood Release Secret Technique: Nativity of a World of Trees to restrain the opponent while Madara uses Fire Release: Great Fire Annihilation to burn the forest. Hashirama then taunts Madara if that's all he's got by creating a deeper forest and Madara responds by creating an even bigger and stronger fire, resulting in a massive explosion.
