Dragon Force

 

• Hidden Fire Form - Crimson Lotus: Phoenix Blade("不知火型" - 紅蓮鳳凰剣 "Shiranui Gata" : Guren Hōō Ken): Natsu ignites his entire body with fire, and then charges towards the target, sending them into the air with a sharp uppercut. Natsu then, in a similar manner to Fire Dragon's Sword Horn, headbutts his target. This spell appears to be Natsu's strongest, as it was able to overpower Zero's strongest spell, Genesis Zero, something that Crimson Lotus: Exploding Flame Blade could not, although, this could be because Crimson Lotus: Phoenix Blade relies on piercing power, rather than explosive power. This destructively unstoppable spell was used to defeat Zero.
