This is not a single whole story. This is a series of sometimes unrelated stories revolving around the idea that the power of the AllSpark that Sam Witwicky destroyed, went somewhere, to someone: Harry Potter.

Snippets of Harry's life with three giant robots. Who said that the life after Voldemort was boring?

Jazz's broken body was put back together into his alt form. The wrecked silver car was accidentally hauled to a scrap yard, where an unwitting Harry Potter took it & restored it to working order, and with a little bit of magic, Jazz's Spark was revived...

Harry makes friends with a giant, alien, robot. Who happens to be frozen and hidden inside the Hoover Dam. But don't worry, Harry doesn't mind the lack of response. And Megatron only seems to mind the annoying little flesh bag a little bit.

MOVIEVERSE. HP crossover. When a Transformer crashes into Harry Potter’s garden, neither wizard nor machine know exactly what they’re letting themselves in for. Especially one unsuspecting Barricade.

IT’s one thing to be tossed thru the Veil for something he didn’t do. It was quite another to wake in his animigus form in a world not his own. Harry just knew someone was laughing at him somewhere. Mech/Mech pairings inside.
