Maybe there's a plot where Hermione starts researching a way to combine magic and technology after coming across some old texts about Inspector Gadget's world. She creates a device that allows the characters to travel between the two worlds. Harry then teams up with Inspector Gadget to stop a powerful dark wizard who is planning to use the power of both magic and technology to take over both worlds. This would involve a lot of action, with Harry using his magic skills and Inspector Gadget using his gadgets in a coordinated effort.
Well, it could be that some fanfiction writers might combine elements of the magical world of Harry Potter with the high - tech gadgets of Inspector Gadget. For example, they could create a story where Harry uses Inspector Gadget - like devices in Hogwarts to solve mysteries or fight dark wizards. Maybe the invisibility cloak could be enhanced with Inspector Gadget's technology to have additional functions.
Inspector Gadget himself is obviously very popular. His clumsy yet endearing nature makes for great storytelling. Penny, his niece, is also a favorite as she's often the real brains behind Gadget's successes. And of course, Dr. Claw is a key character, being the main antagonist.
One interesting story could be about Inspector Gadget getting a new high - tech gadget that has a mind of its own and causes all sorts of chaos in his missions. Another might be a story where he teams up with a young inventor who helps him upgrade his existing gadgets.
Perhaps Hermione, who is really into books and knowledge, stumbles upon an ancient spell book that contains the instructions to create a unique gadget.

Well, in the vast world of Harry Potter fanfiction, 'Inspector 13' could be many things. It could be a secret agent - like figure, working undercover to solve mysteries in the wizarding world.

Since it's fanfiction, the possibilities are really endless.
A crossover with Scooby - Doo would also be cool. Picture Inspector Gadget teaming up with the Mystery Inc. gang to solve a case. Maybe there's a villain using advanced gadgets to create spooky illusions, and Inspector Gadget's own gadgets add to the chaos and comedy as they try to unmask the bad guy.
In a crossover with the Transformers, Megatron could be the main villain. He might be interested in stealing Inspector Gadget's advanced human - made gadgets to use against the Autobots. Inspector Gadget would have to use his wits and his gadgets, along with the help of the Autobots, to stop Megatron's evil scheme.
