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.


Harry and Hermione walked through the crowd on the train platform at Hogsmeade Station, heading towards the hairy man who towered over the students calling out for First Years. Hermione was slightly intimidated by the big man, but compared to Wrex when he was drunk the man, introduced as Hagrid, was not that intimidating to Harry. Hell Tali, when she was going off at a stubborn piece of equipment, was more intimidating.

They were led down to a series of boats that floated out across the lake. The view of the castle with the windows lit up and was probably the third most spectacular view Harry had seen while on a planet. Nothing terrestrial could compare to some of the stellar phenomenon, such as the Citadel sitting in the middle of the Widow Nebula or the sight of the entire Migrant Fleet floating through space.

On the far end of the lake, the students were escorted up a long set of stairs, which most of them struggled significantly with. While the students, except Harry and a red haired girl, were recovering their breath they were introduced to Professor McGonagall who gave them a rundown of the four Houses and then left them to get themselves together.

"So, you're the one who brought the freaks into Diagon Alley." A snide voice came from behind Harry. "Who the hell are you?"

Harry turned and saw a scrawny bleached blond flanked by two larger boys, who were all about as intimidating as an a non-Biotic Volus with a malfunctioning environmental suit.

"I am Harry Shepard nar Normandy of Clan Urdnot." Harry replied. "And those 'freaks' are my crew and family."

"Do you know who I am?" The Blond said, stepping forward.

Taking the move as a threat, Harry did as his family had taught him. Firstly, he threw up a Biotic Barrier between the confrontation and the rest of the students. The Barrier was weak, it would not hold up to any gunfire or serious Biotic attacks, but it was good progress for an eleven year old and would separate the conflict from the innocents.

The second thing Harry did was activate his Defence Drone. He had gotten the program for it from Tail and it was designed to learn patterns the more specific actions were used. Harry's drone was simply set to mildly shock the two bookends whenever they approached him. Leanna had always wanted pets but they were not allowed onboard spaceships, so she named Harry's Defence Drone 'Puppy' and later, when she got one, her own was dubbed 'Kitty'. The two boys were too dumb to realise how it was set and were getting shocked ever second or so.

For the Blond boy himself, Harry stepped in and gave him a headbutt, Krogan style. Nothing said 'Don't fuck with me' like a Krogan Headbutt. It was an almost perfect Krogan Headbutt, just the way Wrex had taught him, and the Blond went sprawling onto the ground. Harry walked forward and knelt down in front of the prone Blond.

"I don't particularly care who you are." Harry said. "But there's two things you should know. Firstly, no one insults my family. Entire Planetary Governments have learnt that one the hard way. Secondly, I was not born Harry Shepard. Captain John Shepard adopted me as a baby, but you may have heard my real name. I was Harry Potter. Whatever you think or have heard about Harry Potter, be clear that Harry Shepard nar Normandy of Clan Urdnot is significantly more dangerous."

"Mister Shepard, can you please let Mister Malfoy up and release your classmates." Professor McGonagall said from the door to the Great Hall.

Harry stepped back and dropped the Biotic Barrier.

"Puppy, heel." He ordered and his Defence Drone stopped shocking the two boys and moved to Harrys shoulder, bobbing up and down slightly like a happy puppy.

"Wait until my father hears about this." Malfoy said.

"Wow, daddy's boy much, you little Pyjak." Harry said. "Does he tuck you in at night too? Bosh'tet."

An embarrassed blush washed over Malfoy's face as the rest of the class, except his two book ends, laughed. Harry led the students into the Great Hall behind Professor McGonagall. Hermione was walking just behind and to his right while Puppy floated just over his left shoulder.

The Sorting proceeded quickly but Harry only absently paid attention. The redhead girl who had not been exhausted by the climb of the stairs went into Hufflepuff. The Blond and his bookends went into Slytherin. Hermione sat on the stool with the Sorting Hat on her head for quite a while before being sorted into Ravenclaw.

"Harry Shepard." Professor McGonagall called out.

Harry walked up and the Hat was placed on his head.

"Interesting." The Hat said in his mind. "The sense of duty of a Quarian, the discipline of a Turian, the aggression of a Krogan, the curiosity of an Asari and the adaptability of a Human."

"Of course." Harry replied silently. "They are my family."

"Well, I can firmly say the only House you aren't suited to is Slytherin." The Hat replied. "It's not that you can't be ambitious or cunning, but it is not what drives you. You are brave, smart and hardworking, so you would be suited for any of the other Houses."

"So… If I am suited to the other three, how do we choose?" Harry asked.

"It is which suits you most." The Hat replied. "An in this case, I think the answer is based in one of your father's sayings. 'An N7 can be a lot of things. Brave, aggressive, calm, technical or biotic. But the one thing an N7 can't be is stupid. You can accept a stupid soldier, but not a stupid N7'. Despite not having the formal training, in your heart you are an N7, so the only choice is…"

"Ravenclaw." The Hat called out through the Hall.


"The two troopers who were holding the entranceway become the Rearguard as the extraction force bring the VIP's to the extraction point." Tali said.

Tali and John Shepard were the only ones standing around the holographic table in the Normandy's briefing room, with the holograph showing the proposed mission area.

"Estimated Mission Time, from touchdown to extraction, is estimated at one hour and ten minutes." Tali continued. "I am ready to brief the extraction team as soon as you give the word, Captain."

"What extraction?" Liara asked from the door, looking at the display. "Is that Hogwarts, John?"

"Captain?" Tali said, an angry tone to her voice. "You said this was a sanctioned mission."

"Liara, shut up." John snapped. "Tali, finalise your report."

"It's all in there." Tali growled, throwing a data-slate onto the holographic table, disrupting the image. "I don't like having my time wasted, Captain. I have not slept for the last three days to get this plan and my gear ready. I thought you trusted me to get it done, not to make me look like a complete Bosh'tet."

"Tali, this was not designed to make you look like a fool or waste your time." John said. "Liara was not in the loop on this issue. There are seven children of Alliance Military or Government Officials who are attending Hogwarts, including Harry. Your plan is to be the emergency extraction plan should the Alliance need to get them out for any reason, ready to go at a moment's notice."

"So, I'm not going to lead the team?" Tali asked. "But you said I would."

"One of the first things they teach you in Officer Training School, and beat into you in N7 Training, is always plan any Op as if you were going to personally lead it doing the most dangerous tasks. That way you plan to have the mission completed with the highest chance of everyone getting out alive." John explained. "I'm sorry that you feel I deceived you, but this was something I was confident you could do well, which you did, and Alliance Command agreed with me. Alliance Command knows this is your plan and are willing to accept it without revision. And Harry's life may depend on this plan, so I could not think of a better person to plan it."

Tali semi-stormed out of the briefing room, still upset that it had not been a mission she was going to lead but still somewhat proud that Shepard trusted her enough to plan a contingency to get their Harry out if things went bad. One the door closed behind Tali, John rounded on Liara.

"What the hell was that?" John demanded.

"Well…" Liara began.

"Stop." He interrupted. "I love you, you know that, but that was unprofessional and a security breach. You are never, I repeat never, to enter the briefing room while it is in use unless you are invited to said briefing, XO or no. You potentially compromised not only our working relationship with Tali but also the plan to keep our son safe. No one, outside of Tali, myself and Alliance Command, was to know that a plan like that even existed."

"I'm sorry." Liara said in a small voice, sounding much more like the young archaeologist he had met years ago than the confident XO and wife he had come to know and love.

"Just think in future." John said. "And give it a day or two and then go apologise to Tali."
