Littlefoot's Adventures of Pokémon Heroes is the final Land Before Time/Pokémon crossover film planned to be made by Daniel Esposito. It will appear on Google Drive in the near future.
Littlefoot, Cera, Ducky, Petrie, Spike, Chomper, Ruby, Guido, Grandpa Longneck, Grandma Longneck, Kion, Fuli, Beshte, Ono, Bunga, Toaster, Lampy, Radio, Blanky, and Kirby (along with The Vultures, Jiminy Cricket, Zazu, Kronk, Zhane, Jeremy the Crow, Princess Odette, Prince Derek, Jean-Bob, Speed, and Puffin) must help Ash and his friends to protect the two special water Pokémon called Latios and Latias from two women named Annie and Oakley, whom Sharptooth, Ozzy, Strut, Ichy, Dil, Rinkus, Sierra, Red Claw, Screech, Thud, and Rothbart work for.
- The Vultures (Buzzie, Flaps, Dizzy, and Ziggy), Jiminy Cricket, Zazu, Kronk, Zhane, Jeremy the Crow, Princess Odette, Prince Derek, Jean-Bob, Speed, Puffin, Sharptooth, Ozzy and Strut, Ichy and Dil, Rinkus and Sierra, Red Claw, Screech and Thud, and Rothbart guest star in this film.
- This is an NTSC film with NTSC bits from The Land Before Time films, The Lion King films, The Brave Little Toaster films, The Jungle Book 1 and 2, Pinocchio, Mickey's Christmas Carol, Mickey's Magical Christmas: Snowed in at the House of Mouse, The Emperor's New Groove, Kronk's New Groove, and The Swan Princess films.
- This film will be the last film in the Last Before Time/Pokémon series not only because of Littlefoot and his friends guest starring in the Winnie the Pooh/Pokémon sequels from Pooh's Adventures of Pokémon: Jirachi Wish Maker onwards, but also because Pokémon Heroes marked the final appearance of Misty in a Pokémon film and she never appeared in another one ever since.
- Yru17 originally planned to re-edit this film with a large amount of guest stars, but he retired from re-editing anymore crossovers, so Daniel Esposito will make this film with a small amount of guest stars instead.
