I may make a separate page for my Zatch Bell x Other Series crossover AUs. This page only contains the info, details, etc on my non-Zatch Bell x Other Series.
Dead Crisis (The House Of The Dead, Time Crisis and Resident Evil Crossover AU Fanfiction)
A crossover fanfiction that I've conceived back in 2007 but never got the chance and motivation to write it. Originally it was titled Darkness Princess and Sonic the Hedgehog characters were also in the crossover fanfiction but both title and Sonic were scrapped. The full name of this crossover fanfiction is Resident Dead Crisis.
VIcinity: Finalized (Final Fantasy Crossover AU Fanfiction)
This is the only Vicinity storyline that doesn't contain Zatch Bell characters. This one featured the Final Fantasy characters from Final Fantasy Tactics, and Final Fantasy I-X. Originally it also have Final Fantasy XII and newer game titles but I scrapped those games so I can focus on the older titles. This crossover AU takes place in a modern setting.
Untitled (A Digimon, Pokemon, Monster Rancher and YuGiOh Crossover AU Fanfiction)
This one is in early stages. Mostly likely I'd write it out of nostalgia. May contain Tai (Digimon) x Ash (Pokemon) crossover ship.
Unitled (A Cartoon Network Crossover AU Fanfiction)
Based on a early crossover AU I imagined from my childhood during the 90s. I don't recalled the plot through. Maybe someday I'd write it.
