Tortomon

Tortomon is a Champion Level reptile Digimon that resembles a jagged tortoise.

Digimon 02
A Tortomon was first seen when Daisuke Motomiya and Veemon accidentally saw him urinating (that seen was cut out). When rocks fell and Tortomon knocked them away, he chase Daisuke and Veemon to a cliff near the ocean. Just then, Veemon Digivolved to his Champion form of Exveemon and knocked him off the cliff. He washed his hands like Daisuke requested him to do [to follow up on that cut scene] and walked off laughing. Another Tortomon is seen as a partner to an American Digi-Destined named Lou. The same Tortomon appeared during the final battle against MaloMyotismon.

Digimon Tamers
A Tortomon was among the many Digimon seen through the rip in the sky during Vikararamon's rampage.
