Alex's Adventures of The Jungle King is an "Alex's Adventures" crossover by Lionheart Captain. It appeared on YouTube on May 24, 2012. A new remake version made by Daniel Esposito will appear on Google Drive in the near future.
- Because the original film's cast was never credited, this is the only video crossover to have no ending credits.
- Vitaly the Tiger, Gia the Jaguar and Stefano the Sea Lion make cameos in Alex's fantasy.
- This marks where the gang first met Leonette.
- In narrative scenes, Leo Lionheart, Tantor and Terk appear.
