Leomon is Leonardo Dicaprio's next stage. Leomon evolves into IceLeomon(when in contact with Titanic iceberg), GrapLeomon when in Inception or MadLeomon when in Django Unchained. Leomon's final stage is SaberLeomon, stage he gets when using Wolf of Wall Street monies.
Leomon is Animal Man digimon. He battled Devimon in Digimon Adventure. In Digimon Adventure Leomon was played by Matt Damon, not Leonardo Dicaprio because he was busy swimming up from the bottom of the sea where James Cameron had thrown him.
