Disclaimer: I do not own Harry Potter or Mass Effect... I would buy them all but I am broke.

Summary: Harry Potter is not raised by his Aunt, instead he is raised by his Mother's Cousin and his friends on a little ship called the Normandy. Harry Potter Mass Effect Crossover

A/N: This Fic ignores the Storylines of Mass Effect 2 and 3. Don't get me wrong, I love the games, but Harry is raised by the crew of the original SSV Normandy SR1, so no Collectors and no Reaper invasion… at least not on the timeframe of the Games.


"Joker, bring us about. Target the one on the right." John Shepard ordered.

Liara turned to one of the comms tech, a Samantha Traynor. Traynor had been part of the fit-out crew for the new Normandy and had elected to stay on board when it was commissioned.

"What's the status of the boarding party?" Liara asked.

"Theirs or ours?" Traynor asked.

"Don't worry about us." Wrex said over the comms. "We're having fun. He He He."

Wrex and his four Krogan Battle Masters were on one of the pirate ships that were attacking the Normandy.

"We have five Quarian Marines and two Asari Commandos guarding The Loft. We have a squad of Alliance Marines protecting Command Desk. The other ten Quarian Marines are in Engineering under Tali's command. The rest of our forces are containing the boarders on Troop Deck." Traynor informed.

A shudder ran through the Normandy. It looked like the nanite enhanced Ablative Armour that Tali and Adams had come up with was holding for now.

"Is The Loft primed?" Liara asked.

"Yes. Primed and ready." Traynor confirmed.

The Loft was the name for the apartment up on the top deck for the Shepard family. It was the most armoured section of the entire ship and was also a massive life boat that, if ejected, was programmed to head back to Earth. Leanna was safe up in The Loft.

"We got the last ship." Joker reported. "Except the one Wrex is having fun tearing to pieces."

"Let's end this." Shepard ordered. "All forces on Troop desk, set armour to full recycle. Gas Troop Deck in ten seconds. Move in under the cover of the gas and take down any who are still standing."


Harry and Hermione were sitting in the Great Hall waiting for the Hogwarts Express to take them home for the holidays when Hermione's Omni-tool beeped.

"My parents said yes." Hermione said. "You and your family are all welcome on Christmas Day. Those who can make it."

"That is good news." Harry replied.

Most of the students, except the few who were staying at Hogwarts over the holiday, were getting up and moving out of the Great Hall. Hermione rose and Harry followed, but when they got out on the massive front lawn, while everyone else was making their way to the carriages, Harry waited by the doors.

"Aren't you coming?" Hermione asked.

"Nope." Harry replied as a deep thumping noise began to rise, felt mostly in the chest. "Here comes my ride."

The Alliance Shuttle came in from over the Forbidden Forest and touched down on lawn away from the carriages. As soon as it landed, two Alliance Marines jumped out to take up defensive positions as Harry rushed for the door. Once he was aboard, the two Marines backed into the shuttle and the door closed as Harry took his seat and buckled in.

"Hello Oma." Harry said, greeting Hannah Shepard.

Hannah nodded to Harry as the engines powered up and the noise raised with it. Harry looked out the window to see most of the other Students staring at the shuttle in shock. Hermione seemed to be rolling her eyes at him. The shuttle lifted off and began a steady ascent into orbit, the noise dying away significantly once they were airborne.

"Is the Normandy back in orbit?" Harry asked.

"No. But we do have a rendezvous to make." Hannah replied with a muted smile.

The shuttle exited the atmosphere and Harry looked around and his eyes instantly locked onto a ship in high orbit.

"That's the Neema!" he declared.

"Yep." Hannah confirmed. "They are delivering a package from the Citadel before returning to the Migrant Fleet, at my behest."

The shuttle docked with the Neema and three figures entered the airlock, which cycled through.

"Big Brother!" Leanna said, shooting towards Harry in her hardsuit.

"Uff." Harry grunted as his little sister barrelled into him.

After a second to recover his balance he looked up and saw the other two who had been in the airlock.

"Tel'Herra. Reli'Herra." Harry greeted.

"Harry'Shepard." Reli said with barely concealed excitement in her voice.

"Admiral Shepard." Tel greeted. "I trust you are well."

"Indeed, Tel'Herra." Hannah replied. "I assure you, I will treat Reli as my own, just like Harry and Leanna."

Tel nodded and started to turn back towards the Airlock while Reli stood nervously inside the shuttle.

"Reli, you are coming with us?" Harry asked.

"Um… yeah… I… Oh Keelah." Reli said.

"I have invited Reli to spend the next few weeks with us, while you are home from School." Hannah explained. "Unfortunately, the Normandy is on a… mission at the moment and I thought it would do you good to have some more company and Reli good to explore Human Culture a little."

Tel said her goodbyes and the airlock closed behind her, allowing the shuttle to undock from the Neema.

"Daddy and Mummy are going to Omega." Leanna supplied helpfully. "Something about Aria and a reminder that daddy's rule beats her rule."

"That pirate woman." Hannah muttered. "Sometimes I think she pisses off John on purpose so he will go put her in her place. I think she likes it."

The three youngsters sat down and chatted before Harry remembered something.

"Oma, will Reli be able to come over to Hermione's place on Christmas day? I know Hermione said we had permission but I thought it would just be you and me." Harry asked.

"Don't worry, Harry dear." Hannah replied. "I have already spoken to Miss Granger's parents. They are aware both Leanna and Reli will be joining us for Christmas Day. Mister Granger mentioned that their Quarian Assistant, Nori'Tenos nar Hellos, will be joining us as well. They assured me that they have appropriate food and facilities for Reli."

"This is going to be so much fun." Harry exclaimed.

Finally getting over her nervousness of her first time off the Neema, Reli did what she had wanted to do since she had stepped into the Airlock. She hugged Harry. After a few seconds she stepped back from the hug and cocked her head to the side.

"So Harry." She began with false sweetness in her voice. "Who is this Hermione?"

"Reli!" Harry groaned, gaining a giggle from both Reli and Leanna.
