You know, if I had to take a guess at Neo favourite digimon, I would have said Chocolate Terriermon Lopmon.

Also, Kudamon's pretty cool. But not as good as DORUmon. He's not purple, has no jewel on his forehead, and he didn't inherite the X-antibody and survive the destruction of the world.

DORUmon's kinda Kudamon's boss. Both are Royal Knights, but Alphamon's the leader, wheras Kentaurosmon was just a regular knight.


Also, Calumon is definitely the second best. Kudamon can be third.
