HP/Transformers crossover. After the War, Harry is betrayed by the Wizarding World (surprise) again. He, Hermione and Teddy are sent through the veil. In apology for his sucky life, the Powers That Be send him and his family into a new world, along with a dash of de-aging for a second chance. They may have failed to mention the upcoming arrival of extra-terrestrial sentient giant robots.

Prologue: The Last Trial of The-Boy-Who-Lived

"This court finds this monstrosity to be an affront against nature and magic," Umbridge said in that grating simper of hers. She was in her element. "The abomination will be disposed of forthwith."

Both silenced, Harry sent as much love and promise to where little Teddy was trying to disappear. And when a metamorphmagus tries to disappear they do. His arms had become wooden and flat where they were chained to the chair, and the rest of him was determinedly mimicking the grimy leather seat.

The masked figure of Walden Macnair stomped across the "courtroom". Harry knew this room, but it wasn't courtroom ten, it was the Veil Room. About half the Wizengamut was seated around the amphitheatre, though definitely biased against him. Harry was unsure why it would be so, why hadn't Umbridge just limited it to people she was sure back her if she wanted an audience? He couldn't really bring himself to care though.

Macnair hoisted the silently frantic toddler over his shoulder and tossed him through the Veil. Tossed him.

Harry's cynical resignation was washed away in a fury so intense he wondered if Voldemort was around. Some small part of him noted his shackles were humming with suppressed magic.

"Harry James Potter, you are brought before this court on charges of murder, line theft, practising forbidden arts, as well as other minor charges too numerous to list. How do you plead?"

"Not guilty," Harry ground out.

"Having seen the evidence, I bring this to a vote. All who find the defendant not guilty?"

Maybe a quarter raised the wands. None of them were happy. Harry managed a weak smile of thanks to them. Umbridge seemed unhappy that some people would dare disagree with her.

"All who find the defendant guilty?"

The rest raised theirs, vicious and triumphant smirks on their faces.

"This court finds the defendant guilty. And thus sentenced to the Veil. Blackhood if you would."

The moment the chains loosened, Harry stood and strode up to the Veil. He turned to face the assembly.

"Farewell, those of you who see the true monsters here, I plead you leave. Magical England is too sick to continue, I wish you the best of luck elsewhere. For the rest, magic as my witness I curse you, may you receive every suffering you so truly deserve."

Harry spun on his heel and walked through the Veil. Not bothering to witness their horrified faces as the cursed saw a lightning bolt appear on the back of their hands.

Harry wasn't sure what he expected to find on the other side of the Veil, but it he expected something. All he saw was white, and felt nothing but the brush of fabric as he moved. He was knocked out of wondering where the whisperers were by a child's cry.

Teddy!

Harry pushed his way through, and almost tripped over the wailing toddler. He'd sounded much further away than he apparently had been.

"Hush, little Teddy-bear. Harry's here," he soothed, rocking and humming. The little guy's crying subsided, to sniffling, and quite quickly he was curled up asleep against Harry's chest. Leaving him at a loss again. "Now what?"

We talk, my dear child.

The voice came of nowhere, and though every paranoid instinct war had ingrained on him screamed for him to tense, Harry felt himself relaxing. There was a warmth in the voice that he didn't quite recognise but reminded him oddly of Ollivander.

Perhaps you should explain, sister.

Another voice, cool and impersonal. Harry got the impression that the second speaker was a perfectionist, but the voice held promise of something else.

Oh yes, I am Maga.

And I am called Primus. I am to technology what my sister Maga is to magic.

"Nice to meet you, but since I went through the Veil of Death shouldn't I be talking with him?"

The Veil isn't just a gateway to death. What it is a gateway to here. The Forum of The Powers That Be. People don't come back from it because we judge and send them somewhere else.

Sadly people forgot its purpose, so all we've received in recent years were criminals.

Well... Maga began before breaking into a chime-like giggle. There have been one or two good souls, who have come before us.

"Hermione? Sirius?" Harry couldn't stop himself asking.

"Right in one, kiddo!"

Harry whirled to face his godfather. Who looked quite well, actually. The worn, haunted look he'd had for all the time Harry knew him was gone. His eyes glinted with mischief, something Harry had only seen a handful of times.

"So, what are you doing here then?" Sirius began, affecting a stern demeanour and shaking his finger at Harry, "I'm fairly sure I ordered quite explicitly in my will that we shouldn't meet until you'd raised some mini-Prongslets."

"What? I never heard your will, and closest I'm likely to get to a mini-me is Teddy here."

Said toddler was looking at Sirius curiously. He waved and his appearance changed to mimic a baby-Sirius. With bright green hair.

Sirius laughed at the young metamorphmagus' antics, then frowned, "Dumbledore barred you I take it?" He gestured vaguely. "Doesn't matter, so what was wrong with Hermione? You seemed to like each other."

Harry's confusion grew. "Hermione? Ewww, she's my sister. What happened to her anyway? She went through the Veil just before us."

Sorry, but she went on. Her tasks were done and she had no debts owed to her. Nor could Primus claim her.

Harry felt the patented crush of a Hermione-Hug and a whisper in his ear, "Don't worry, we'll find each other again. Look after yourself and Teddy for me."

"Of course," he whispered back. Then what Maga said triggered a wash of dread. "Tasks, debts," Harry groaned, "Why do I have a feeling I'm not going to like this?"

On the contrary, we think you will like it very much.

But before we get to that, I feel I should explain my hopes in your old life. First off, Dumbledore was meant to deal with Riddle. Then when it became desperate, I set up the prophecy.

"What!"

Calm down, I handed it off to Fate, who took some liberties with it. You were just meant to halt Riddle. The respite would give Dumbledore time to deal with the Horcruxes. But nooo... Fate had to... Maga's further comments disappeared into indecipherable rumbles.

Give my sister a moment to collect herself. You should know, you are one of her favourites. She did all she could, but the Dursleys' rejection of magic severely hampered her freedom to interfere. Worse still they didn't believe in anything to the point that no Power could act.

Thank you brother. As I was saying, Riddle's defeat shouldn't have been on your shoulders. Nevertheless you bore that burden and I can't describe how proud I am. No, the task I had in mind for you was safer, though much more complex.

Harry's ever present curiosity spiked, and he hesitantly asked, "And this task was?"

To prepare the wizarding world to rejoin the non-wizarding. Soon the muggles will uncover them, and would you consider the wizards ready to meet the muggles as equals?

"No, not at all," Harry replied without hesitation.

I asked my brother for help, he gave you a gift which you only really discovered after Riddle's defeat.

"The technomagic I was working on?"

Yes. Though I merely gave you a talent for understanding and repairing things, and prevented you developing a wizard's technological blindness. You deduced how to mix things.

"So you're going to send me back?" Harry subduely asked. Maga had outlined a task he had yet to finish, one he didn't even know he'd been working on. It had been nice to see Sirius again, and to see Teddy off into his care.

There was a silence then, Harry felt Maga's odd presence squeezing his shoulders.

My dear Harry, you really think I'm sending you back to help those poor excuses for beings? No, they've raised their wands, they'll have to weather their curses. And yours, I'm going to have so much fun with that.

As we said, the purpose of the Forum is to determine where to send you on to. Maga has released you from the task she gave you, and we've worked together to make up for what you've suffered.

"Have you?" Harry prompted slowly, he'd suffered quite a bit from people doing things for his own good.

"Yeah! They have, and I think it sounds really neat!"

Harry grimaced, he wasn't sure whether Sirius' seal of approval was a good thing or not.

We've organised a chance for you to experience what our mistakes destroyed; a normal childhood. Maga paused and Harry waited for the other shoe to drop. He was not disappointed as Maga's voice became apologetic and sombre, Not with your parents sadly. Even we can't bring them back without a sacrifice none of you would wish to pay. You'll see them eventually, and you'll have forever to get to know each other.

You won't be with your parents, but you will get a chance to grow up under Sirius' care.

Harry looked askance at Sirius who was dancing with eagerness. How was he meant to be a parent if he hadn't grown up himself? Slowly surrendering to the inevitability of this "final reward", Harry asked a couple last questions, "So, how is this going to work? How young am I going to be? And what's going to happen to Teddy?"

We'll be sending you to one of the worlds under my purview. Another Earth, without magic or Maga's children. However, I have my own, who you may meet. In fact, I will in a sense be adopting you all. Besides technology, my other dominion is change. Sirius learnt to change himself, and Teddy is almost nothing but change. Though you won't have magic, I hope my gifts will make up for it.

As for your ages. Teddy will stay four. You and Sirius will each have the twelve years you missed together returned to you. Leaving you nine and him thirty.

"Okay, sounds good. I don't want to go through toilet training again."

"Nor do I want to teach you, pup."

"So... what's the catch?"

Only that you take. Maga's unhelpful comment was all Harry heard as his world went white.

The plan is place Harry in an unusual position as far as these crossovers go. He'll know Sam (and the Witwickys) as Teddy's best friend, not a friend of his. Harry will be a few years older than Sam, and by the time the movie begins he's already a self-made software millionaire. I plan on skipping through most of the movie, with just snap-shots of the beginnings of the butterfly effect. Harry won't be following Sam's plot-line as per SOP for these crossovers, in fact he'll be with Maggie (the signal analysis lady). Teddy may-or-may-not tag along Sam's plot-line. Most of the story in my head picks up after the film, heading off in its own direction. Especially with significant events of Mission City going differently (the Cube? Not destroyed).
