Okay I've got two stories for you, one is already up and the other I haven't written yet but I'm Brin storming.
The story I have been pondering on writing is the historical au idea that Blue Belle Author 1600 had posted and I got her permission to use it if needed. I really like the concept she came up with and I'm a history freak so I may write it. Basically it's el tigre but it takes place during early Latin America. During the time of the Aztecs and Conquistadors, if you're curious about it check out her page. BTW did you know that Manny was Mexican and Frida was Spanish?
The story I already have up is another x-over. It's a crossover fanfic with these cartoon series. El Tigre: The Adventures of Manny Rivera, Steven Universe, Gravity Falls, and Invader Zim. This is a very dark au, extremely dark so be warned but it's also funny. Zim is in there for comic relief. Takes place in the 1920's. An extremely dark and Gothic au filled with devils, vampires, werewolves, nuns, slayers, exorcists, witches, and corrupted priests. This was greatly inspired by animes such as Chrono Crusade, Hellsing, Dance in Vampire's Bund, Dance with devils, and Blue Exorcist also with a little influence from Dark Shadows, Bram Stoker's Dracula, The Wolfman, and Gargoyles.
It's very dark so if you're faint of heart and want to continue seeing these characters in funny stuff then don't read. I've had this story up for awhile and I'm considering taking it down since not many people seem interested. If you don't like it please keep all rude comments to yourself. The title of the story is The Sinners and their Saints.
