Leon arrived at a waterfall spring in Rush Valley, ready to take the fight to the Lightning. Suddenly a blue transmutation circle opened up and pinned Leon to the water. Leon's gate was extracted, as the final sacrifice was collected, but without the Lightning's permission.
Meanwhile, The Lightning arrived in the middle of Central Park, realizing that the green light on his gauntlet lit up without his input.
"That's weird." The Lightning said. "The green light lit up without my input." A mysterious blue aura caught his eye and knocked him out.
Elsewhere, Edward, Winry, and the kids were returning from Arcadia to Amestris to finish off the Lightning. When they arrived at Central, Roy, Riza, Al, and Mei were there, along with Leon.
There was a rumbling in Central Command. A large gate opened, releasing a giant monster, a long and large blue serpentine dragon, the Lightninggeddon. It terrorized Central, using its Lightning Breath to set fires to homes, business, and government facilities. The Amestris Military tried to stop it, but their tanks and guns were no use. The Arcadian and Albion forces couldn't put up much of a fight either. Their planes were blown up by the monster. The Lightning was in The Lightning Wing, charging at the Lightninggeddon.
"You disobeyed me, stupid beast!" Lightning snapped. "Behold, your master's true power!" The Lightninggeddon just fired a lightning beam from his mouth and destroyed the Lightning Wing, while the Lightning escaped. He landed near Ed and the gang, with his gauntlet still on.
"Lightning, give up!" Edward said. "Call off this monster immediately!"
"I could do that if I had the power, but the Lightninggeddon is too powerful to control." Lightning handed Ed the gauntlet. Harry Potter arrived from a portal and joined in hands with Ed and Leon.
"Are you ready?" Ed said.
"Always." Harry answered. The five stones circled around Ed, Harry, and Leon, giving them spiky yellow hair and red eyes.
"LET'S DO THIS, MAGIC ALCHEMY STYLE!" The three heroes shouted in unison. Ed came charging at the monster, dodging his attacks and attacked his gut.
"Harry, you're up!" Edward said. Harry Potter dodged the Lightninggeddon's attacks and damaged his gut.
"Go, Leon!" Harry encouraged. Leon dodged the Lightninggeddon's attacks and damaged his gut.
Ed came back again, charging at the monster, dodging his attacks and attacked his gut.
"Harry, you're up!" Edward said. Harry Potter dodged the Lightninggeddon's attacks and damaged his gut.
"Go, Leon!" Harry encouraged. Leon dodged the Lightninggeddon's attacks and damaged his gut.
"TAKE THIS, TRIPLE FINISH!" Harry, Leon, and Ed said in unison. They charged in a golden flash of light, right into the monster's mouth, causing the Lightninggeddon to explode, leaving purple blood on the buildings and leaving body fragments crashing into cars and buildings.
Ed, Harry and Leon returned to normal state, restoring everyone who had their gate removed. With the Lightning still weak, there was one thing left to do. Sadly, the Dragon Lady stabbed the Lightning, impaling him in the chest, stealing the moment away from the Elric Team.
"When this is over, the world will not be big enough for all of us." The Dragon Lady said. Leon knocked the Dragon Lady out, making her fall to the ground. Harry and Ed shot fire blasts from Harry's wand and Ed's fist in typical Black Lagoon fashion but instead of guns they used magic/alchemy powers. The Dragon Lady was no more, and the war was finished before it could really begin.
"The fighting's over." Roy said. "Amestris has been beaten up very badly."
"Guess the Arcadian and Albion forces will have to occupy Amestris to build it back up." Riza added.
"The Cretan forces will occupy it as well." Ed mentioned. "For now we will just wish Harry and Leon a safe trip back to their world." Harry opened up a portal with magic, taking Leon with him.
"Good bye, Leon!" Ed said, waving to Leon.
"I have important Ministry duties to attend to." Leon said. Leon waved good bye as Harry and Leon went safely back to the Wizarding World.
"What do we do now?" Winry asked.
"We go back to Resembool, the town that's as cool as me!" Edward said, smiling. Everyone went to Resembool as "Let It Out" played in the background. The war was won, the Lightning was defeated, all was well in the world. For now, at least.
THE END
