Need Help Decideing on A Fan Fic to Write

As the title says I need help in deciding in what fan fiction to write, I have about three stories in my head that I want to get off the ground but for the life of me I can seem to choose which to start with, so here's the thing, I'm gonna tell you guys the titles of my story ideas and their synopsis and you guys type in the comments below what do you want to see more, with that out of the way, lets get started.

1. Rodan: King of the Monsters- After a full scale alien invasion with King Ghidorah and Mechagodzilla leading the assault, Godzilla has finally fallen, he gives his remaining power to a fallen Rodan, a somewhat homage to Godzilla vs Mechagodzilla 2, and not only does it revive Rodan but also furthers mutates him into something far more powerful, now with the GDF suffering major losses with Kiryu and Mogera heavily damaged and the aliens coming back with an upgraded Gigan, augmented with the remains of Mechagodzilla and DNA of King Ghidorah, humanity's fate now rests on the shoulders of Rodan

2. Transformers: The New War- Basically a story that I was gonna start but the other two ideas crept in and I got sidetracked, it would be based on the voice actor memes I did a while back with the same roster of Autobots and Decepticons that I listed off.

3. Power Rangers: Monster Squad- A multi crossover fan fic done right if you ask me, where five teenagers with attitude from different series are recruited by Dr. Van Hellsing to fight Dracula as well as another villain who wants to awaken Typhon of Greek mythology, it's based on a meme I do plan on posting later and I'll give a further explanation of the idea when I get to that

And there you have it, the three fan fic ideas that are fighting it out in my jumbled mess of madness I call my brain, which ones do you guys want to see first, comment below and let me know.
