Littlefoot's Adventures of Loonatics Unleashed is another upcoming Land Before Time TV Series crossover planned to be made by Daniel Esposito. It will appear on Dropbox in the near future.
Littlefoot and his friends and grandparents (along with Scooby-Doo, Rex, Alex, and their friends) time-travel to the year 2772, the year that a meteor strikes the fictional city-planet of Acmetropolis, knocking it completely off its original axis. Instead of destroying the planet, the meteor crashes in a waterfront, releasing waves of supernatural energies causing some of the planet's residents' genetic codes to be severely altered, granting them special abilities and strengths. A mysterious and powerful woman called Zadavia calls upon six teenagers of the affected residents to form a team of superheroes. She becomes their commander, dispatching them for the purpose of combating any and all threats to Acmetropolis and its citizens. The newly formed team is known as the Loonatics and reside on the 134th floor of a large tower. These characters are the descendants of the classic Looney Tunes characters, according to multiple press releases and official sources. Descendants of other Looney Tunes are unverified, though they can be inferred in certain situations.
It is later revealed that Zadavia is in fact an alien and had used her powers to knock the meteor slightly off-course, preventing the total destruction of the planet. It is also revealed that a mysterious figure later revealed to be Zadavia's older brother named Optimatus caused the meteor to strike Acmetropolis in an attempt to destroy his sister.
In the second season, the show takes on a lighter tone and many more descendants of other Looney Tunes character are introduced, the majority of which only appear once in the series. The super villain characters from the previous season are rarely mentioned or appear. Zadavia becomes a less mysterious figure and regularly participates with the Loonatics in their adventures. Two more aliens from Zadavia's home planet are also introduced, Deuce and Keyboard Man. In the season's finale, the Loonatics are temporarily joined by Sylth Vester, and Optimatus is replaced by Deuce as the series arch villain.
