Tortomon

Tortomon is a Reptile Digimon that resembles a jagged tortoise, but he looks more like Anguirus from the Godzilla movies. He is called the Roaring Digimon due to his bellow sounding much like a lion's. Tortomon can withdraw into his heavy, hard shell for protection.

Digimon Adventure 02
A Tortomon was first seen when Davis and Veemon accidentally saw him urinating. When rocks fell and Tortomon knocked them away, he chased Davis and Veemon to the other locations where the other DigiDestined where helping to repair parts of the Digital World that had been damaged, but seemed too intimidating from his anger for anyone else to actually try and fight him off. He finally cornered them on a cliff near the ocean. As a last ditch effort to confuse Tortomon long enough to escape, Davis requested he "wash your hands" since he "Didn't want to get any bad germs" (he did manage to confuse Tortomon into inspecting his hands in a puzzled manner, but apparently it just made him more enraged). Just then, Veemon Digivolved to his Champion form of ExVeemon for the first time and knocked him off the cliff. But Tortomon wasn't done, as he used his Spinning Attack, leading ExVeemon and Davis to cover their eyes in horror, thinking he was coming back for round 2. In reality, he washed his hands like Davis requested him to do (to follow up on that cut scene) and walked off laughing for some unexplained reason. In the Japanese version, it was seen that Tortomon actually urinated before washing his hands. This Tortomon only spoke during his Digimon Analyser segment.

Another Tortomon was seen as a partner to an American DigiDestined named Lou when the DigiDestined had to fight a Cherrymon in New York. That same Tortomon appeared during the final battle against MaloMyotismon.
