Lightning Flame Dragon's Roar (雷炎竜の咆哮 Raienryū no Hōkō): Natsu's alternate, lightning-enhanced version of his Fire Dragon's Roar. Natsu gathers and combines lightning and fire in his mouth, subsequently releasing them in a large, destructive, sparking blast. This spell is capable of traveling great distances, wreaking havoc wherever it passes, as shown when it crossed half of Tenrou Island, generating a large explosion. In spite of the fact that this spell is potentially powerful enough to kill a person, a single use is enough to heavily strain Natsu's body and completely drain him of all his Magic Power.

Lightning Flame Dragon's Fist: Natsu's alternate version of his Fire Dragon's Iron Fist. Natsu engulfs his hand in lightning and flame, and, in addition to being burned after being struck, his opponent's are also struck by a bolt of lightning.

Lightning Flame Dragon's Firing Hammer (雷炎竜の撃鉄 Raienryū no Gekitetsu): Natsu engulfs his fist and forearm in fire and lightning and devastatingly strikes his opponent. Even with its power diffused by Minerva's defense, it was still strong enough to blow away most of the top floor of a large building.

Lightning Flame Dragon's Brilliant Flame: Natsu's alternate, more powerful version of his Fire Dragon's Brilliant Flame. Natsu engulfs his left hand in lightning and his right hand in flames, and, after bringing the two together, generates a large, destructive, sparking blast around his opponent

Dragon Slayer's Secret Art Revision (滅竜奥義 改 Metsuryū Ōgi Kai):

Crimson Lotus: Exploding Lightning Blade (紅蓮爆雷刃 Guren Bakuraijin): Natsu's alternate, lighting-enhanced version of his Crimson Lotus: Exploding Flame Blade. Natsu engulfs one hand in lightning and the other in flames. By swinging his arms around, Natsu creates a highly destructive vortex of fire and lightning, which greatly damages the opponent and pushes them away with tremendous force. This spell is powerful enough to defeat the almighty Guild Master of Grimoire Heart, Hades, in a single hit.
