A/N

So, I am thinking of adding the movies into this story, you know...if I can make it that long. But I need help tracking down the timeline they would fit into.

I apologize for anyone who follows my other stories right now...I'm not gonna lie, I've had a few new ideas for stories, but don't want to follow through with them...so I've written them down for later viewing so my attention hasn't been where it should be. I will get back to my other stories soon.

I do have a major question though, I recall a time where Lucy had traveled back in time sometime after the GMG, I want your guys' opinions, should I save her, or let her die like in cannon?

I do not own Harry Potter or Fairy tail.

"What?! Are you saying that it still exists?!" An elderly man asked standing on top of a magic circle, "but that is impossible! We destroyed everything related to the project."

A woman standing next to him sighed and shook her head, "when construction of the R-system began we quickly destroyed all seven towers...however, it would appear that we missed an 8th one, not far from Akane resort."

A shorter old man sighed and stared at the magical orb that showed a completed tower, "I'm not sure what's more concerning, the fact that the thing looks close to being done, or the fact that intelligence shows that the black magic cult is no longer within the tower."

Another woman scowled, "that's true. It says here that a man named Jellal is heading the project now."

The entire council turned to the blue-haired man, "your twin brother?"

Jellal smirked a little and nodded, "unfortunately..."

A white object burst into the room and came to a halt in the center of the council meeting. The misty dragon turned towards a short older man and to the amazement of everyone in the room it spoke, "my name is Harry Potter. I am an S-Class mage of Fairy tail. Do not trust the one known as Segrain. He is an astral projection from Jellal, trying to manipulate the council to do his bidding. I and a few other mages of Fairy tail are on-site and ready to take the man down.

The misty dragon faded and the elderly man smirked slightly, "I can vouch for that boy. He is one of Fairy tales strongest, and one of the few with a head on his shoulders concerning collateral damage. I might wish to pick his brain about the magic he sent us through. So fascinating."

The blue-haired man had a full-blown scowl on his face when all but Ultear turned to him, magical auras flaring. "Thought you could trick us eh?"

Ultear stepped up beside him, "you'll need your strength. With this falling apart it all depends on you."

Jellal nodded and his body faded into dust, "I'm afraid I can't allow you to interfere with him."

"You two huh Ultear. Such a shame."

Jellal knocked the chessboard he had to the ground. "Some kind of communication magic. The council is on high alert now."

Harry sighed as he stepped onto the island, everything was dying around them. "This thing is sucking the magic out of everything around it...forbidden magic." He growled. He wasn't sure what this tower did, but only the darkest spells sapped the life out of everything around it. The only piece of magic he had come across that was positive when involving sacrifice was whatever his uncle Remus had done the night the red-eyed man came and killed him, resulting in a thin membrane of magic surrounding his body. Master and Porliusica had said that the closest spell they had ever seen to it was the Fairy sphere. One of the three sacred spells to fairy tale, ones he had studied extensively.

"You are correct." Harry whirled around and a blade of ice erupted from his hand, the man froze and raised an eyebrow. "Very good control for a slayer. My name is Simon, an old friend of Erza's."

Harry scowled, "the same 'old friends' that kidnapped her and brought her to the place she had been enslaved for years before she came to fairy tail?"

Simon's eyes widened and he stared intently at the man, "she must trust you quite a bit to tell you that. The answer is yes, however...I am the only one who didn't fall for Jellal's act. I only played along because I knew you would follow us, and together we could take him down."

Harry raised an eyebrow, "say I believe you...Jellal is the same person as Segrain. Declared one of the 10 wizard saints, it won't be that easy, especially if Erza freezes up from the crush she had on him as a child."

"True, but between the Yuuki, the Salamander, the maker mage, and even the celestial mage of Fairy tail we have a chance."

Harry held up a hand and mist began erupting from his hand, opening it showed the fairy tail symbol. "Take this, it'll convince my friends you're on our side." Simmon nodded and vanished in a black mist.

"You are one tough bastard to hunt down Yuuki." Harry whirled around growling, sick of people sneaking up to him.

His ice weapon shattered in surprise as he came face to face with Black steel Gajeel. "What are you doing here Gajeel?"

He scoffed, "what did I just say? I've been looking for you since Salamander beat my ass."

Harry frowned, 'why?"

Gajeel grabbed his cloak, "the drive spell you taught Natsu. He told me all slayers can learn it."

"Heh. Pathetic. And here I thought I'd get a challenge from another Slayer." He grabbed ahold of the Salamanders' head, lifting him by the hair. "Well, I guess Yuuki will give me that challenge."

Natsu chuckled as his eyes opened, "you want to fight Harry huh? Get in line buddy. Harry's taught me quite a bit about dragon slayers. Stuff Igneel never covered. His mother was a genius, even among the dragons. Shall I show you a little something he taught me?" His skin was incased in flame, "Lucy, stay back. You may get burned from if you get to close."

Fire drive.

Gajeel was forced to release the kids' head as the heat erupting from his skin melted the metal on his hand. "What the hell?"

Natsu grinned and cracked his neck. "Oh, man. I haven't used this spell since I trained with Harry, I forgot the boost it gives me." Lucy blinked and her eyes widened as Gajeel was sent flying into the wall, the metal protecting him cracked and some pieces falling off.

Gajeel grunted as he got up, at least one broken rib with that last hit. "Impressive. Yuuki developed that spell?"

Natsu smirked, "no. All dragon slayers can use it. Harry just taught it to me." Natsu raised his hands and a massive swirl of fire erupted over their heads.

Gajeel lost consciousness as he was consumed by the fiery vortex.

Lucy Ran forward as soon as the heat died down, Natsu chuckling. "I also forgot how much it drains me if I overdo it while in that mode." He collapsed.

Harry was confused, "did Metalicana not teach you that? I mean...if you have the lacrima he gave you I can teach you but...I'm kinda busy with that."

Looking around Gajeel growled and took a small silver lacrima out, "what's this got to do with the spell?"

Harry smiled, he truly did love teaching others...and it made it even better than Gajeel was the same age as him. "Drive is a Dragon Slayer ability, it is a type of Magic-amplification technique that brings out the true power of our capabilities as users of Dragon Slayer Magic, excluding the power boost granted by Dragon Force."

Gajeel looked confused so Harry sighed, "in essence, once that thing is embedded in your body upon activation of your drive spell, the Lacrima will release a bunch of dragon slayer particles into your body. Enhancing all of your attributes."

Gajeel growled, "that's true. The moment he said drive, the heat burned through my steel skin and his speed went through the roof. If I help you take these punks down, you will teach me."

Harry blinked in surprise, "deal. Let's go."

Gajeel smirked and his entire body was encased in steel.

Natsu, Lucy, Grey, and Juvia climbed off the boat and looked around. "This place was crawling with guards," Grey mumbled as he saw piles of bodies and even some magical beasts.

Lucy nodded, "we should go in another way, Harry is taking this route. We should make sure Erza or the two cats aren't on a lower floor."

"Right. Good thinking Lucy."

Juvia emerged from the water, "I have found an underwater path into the bottom of the tower."

"That's great!" Grey said.

Juvia smirked at Lucy, "hear that Lucy? Grey complimented me!"

Lucy deadpanned, "that's great...but let's talk about how we're going to get through this path."

Juvia held up a bubble, "I can form these so you guys can breathe."

"That's great. Let's go." Grey said.

Harry growled as he came into a cage where a young Blonde boy was talking about magic destroying humanity. He froze his legs and Gajeel sent an iron spike into the back of his head, knocking him out. "Erza! Are you ok?" He ran up and froze the ropes.

"Is he going to be ok?" Erza asked as she knelt next to the kid.

"He's just knocked out Titania. He'll have a hell of a headache when he wakes up, but he'll be fine."

"What are you doing here Gajeel?" Erza frowned.

"He followed me here. In return for his help taking this place down, I will teach him the Drive spell I taught Natsu."

Erza sighed and nodded, "I can only assume the rest of them are coming too?"

"Have you met Natsu?" Harry raised an eyebrow.

Erza closed her eyes and equipped her armor again and ran off. Harry shook his head, I understand that that armor is a coping device...but she would be so much more eye-catching without constantly wearing it. He and Gajeel ran after her.

The rest of the team Natsu were plowing there way through the wizards at the bottom of the tower, "man, how many people are here?" Grey asked as he crushed a group of bad guys with a giant ice hammer.

Lucy sighed as Virgo knocked the last one out. "We have to find Erza and these guys just keep getting in the way."

Virgo appeared, "princess, that bikini leaves little to the imagination."

Lucy jumped, "what am I supposed to do?! I left my other clothes when we swam down here."

Virgo had a wide smile, "let me help you, princess!"

Grey, who had been eating from a table nearby got wide-eyed for a second, which ticked off Juvia.

Lucy was now in a green dress, "don't I look cute? Thanks, Virgo." She smiled, but then frowned as Virgo vanished, "should I have asked her to bring you a set of dry clothes too?"

Grey, sans a shirt, was fanning his Jeans next to Natsu, who had encased himself in flame, "Nah. This will do."

Lucy frowned, "he's not a dryer." A nearby statue opened up and the platform lowered. "That's weird." She said.

Natsu shrugged, "Hey if they want to get there butt kicked by fairy tail they're doing a pretty good job at asking for it." Natsu said as they ascended through the door.

Unfortunately, they didn't count on a trap as they had been surrounded by the bad guys. Before they could do anything, the group in front of them had been cut down by Erza, and the group behind them either froze, or a steel spike smashed into them.

Natsu looked confused, "I know I've seen that before."

Harry and, to everybody's surprise, Gajeel, emerged behind Erza. "What's he doing here?!" Natsu demanded.

Harry raised an eyebrow and Natsu was instantly shivering as the flames that engulfed him turned white and everyone but Grey and Harry could feel the cold from them. "The same thing Juvia is here for would be my guess. Calm down Natsu."

The pink-haired man growled as his flames came back. "Don't know how you did that."

Gajeel smirked a little. He would never say it out loud, but seeing someone so easily beat Salamander pleased him.

"You all need to leave. Now." Erza said.

"What? No way. We cant do that." Grey and Natsu said at the same time.

Lucy nodded, "it's true! They took both Happy and Aika to Erza."

Erza frowned and shook her head and turned around, "then it's probably Milliana. She's loved cats since we met, they won't come to any harm with her around. Get out of here."

"No way. I owe that blockhead for shooting me in the mouth." Natsu shouted back as he had already begun running off.

"That idiot," Lucy mutters.

"We wanna stay and help," Grey said.

"You all need to leave. Now. With you and Harry, Grey, you can avoid triggering the motion sickness that seems prevalent with dragon slayers."

Harry sniffed the air."salty...why are you crying Erza?"

Everyone else visibly startled as she turned around, tears streaming down her cheeks. "This is something I have to take care of myself. Because win or lose, I'm staring death in the face..."

Harry growled darkly and his fist met her cheek launching her headfirst into the wall. "And what? You're just going to walk into that death due to some childhood crush you had?! You're not at fault here Erza. I've met with Simon, he explained everything from their point of view. You aren't the same little girl who couldn't use magic. You're the girl who was rivals with she-demon, the premier Requip user on fairy tail. You're a member of our family. and if there's one thing I've learned about family, you don't ever give up on them. Funny how the only person who ever got it is Natsu, and he was taught by Lissanna. I will not let you throw your life away due to some stupid cult who brainwashed the kid you knew. Nor will I stand over your grave because you are too stubborn to accept help. Pack your pride away Erza. Jellal is one of the 10 wizard saints. You cannot do this alone, even if you somehow managed to beat everyone else."

Grey, being the only other fairy tail member their other than the two S-class mages to know Lissanna personally flinched. A piece of Fairy tail died that day. "He is right Erza. We want to help, and nothing you say can stop us."

Erza sighed and stood absently rubbing the forming bruise on her face. It took a lot to make Harry angry like that, and suicide was one of those things. "Very well. Since you are here, I should tell you all my story."

She went on to explain the tower they were in, and how the black magic cult had kidnapped her and hundreds of others to build the damn thing, until Erza sparked a revolt and they beat that colt, only to find Jellal had become the same as them. "There was only one way to describe what Jellal had become. Pure, unadulterated, evil."

"Which is why we are taking him down Erza. When have any of us abandoned a friend in need? I seem to recall Lucy challenging the authority of the king of the celestial world for Leo, I know we rag on Grey's little habit, but we stood by him when his friend Leon came along and tried to free Deliora. You know what Natsu and I both did when he was going to throw his life away Erza?"

Erza sighed and did remember the bruises Grey had on his face when they had found the guy. At the time she didn't care, when she was bringing in rule-breakers. "Same thing you did to me I'd imagine."

Harry nodded, "exactly. The difference here is I used my magic to numb the area for you. Couldn't do that for Grey."

Tears streamed down her face again, this time in happiness. "Alright...let's go."
