What would a 'Invader Zim Gravity Falls crossover fanfiction' look like?

Definitely Dib and Dipper. They are both curious and into the strange and supernatural. Dib with his alien - hunting skills and Dipper with his knowledge of the Gravity Falls mysteries would make a great pair.

Well, it could be really wild. Maybe Steven could use his gem powers to try and stop Zim's crazy plans for world domination. Zim, on the other hand, would probably be super confused by Steven's powers and the whole concept of gems.

Often, there's a theme of self - discovery. As Female Zim is a different take on the character, she might be on a journey to figure out who she is in this new form. Also, the theme of adaptation is common. Just like in the original where Zim has to adapt to Earth, Female Zim may have her own unique ways of adapting, whether it's to Earth's environment or to the reactions of the other characters around her. And there's also the theme of power. How does being female change Zim's perception and use of power? This is something that many fanfictions like to play with.

It would be quite strange considering Mabel's age in the show. But if it were to exist, it might explore how the other characters in Gravity Falls, like Dipper, Grunkle Stan, and Ford, would react. Maybe they would be shocked and have to deal with a situation they never expected.

A possible crossover fanfiction could involve Dipper and Mabel trying to get Rick to help them solve some of the really tough mysteries in Gravity Falls. Rick might initially refuse, but then Morty convinces him. And along the way, they get into all sorts of misadventures with Bill Cipher maybe getting involved and trying to use Rick's technology for his own evil purposes.

One interesting Gir crossover Invader Zim fanfiction could be one where Gir teams up with Dib to stop some new alien threat that neither Zim nor the other regular villains can handle. In this story, Gir's unpredictable and silly nature might add a lot of comical elements to the usually tense relationship between Dib and Zim.

I think Steven and Zim would be the most interesting pair. Steven's kind - hearted and positive nature contrasted with Zim's evil and self - centered personality would create a lot of comical and tense moments.

There could be all sorts of fun scenarios! Maybe the Doctor lands in Invader Zim's universe and has to help him deal with some crazy alien threats.

Mabel and Hilda would be fast friends. They both have a love for the strange and wonderful. Mabel would be excited to show Hilda her sweaters and all the cool stuff in the Mystery Shack. Hilda would share her adventures in Trollberg with Mabel. They might even come up with some new and crazy ideas for adventures together, like having a slumber party in a haunted forest. Wendy would probably be a bit more aloof at first, but as she gets to know Hilda, she'd start to warm up and they could go on some more adventurous outings, like climbing a really tall mountain in Hilda's world.

Well, I think Lance would be really intrigued by Mabel. He'd probably be impressed by her colorful sweaters and her positive attitude. Mabel, on the other hand, would be excited to meet a real - life space hero like Lance. She might even try to set him up with one of her friends in Gravity Falls.
