Crowmon

Yatagaramon (known as Crowmon in Digimon Data Squad) is a Bewitching Bird Digimon named after the Yatagarasu of Japanese mythology. Just like his lower form, Falcomon, he has two different designs; the original, that was featured in the Digimon Accel, and the new one to serve as a part of Falcomon's line in Digimon Data Squad.

Apparently the new design of Yatagaramon has now replaced the old one in most Digimon media.

Yatagaramon (Original)
The jet-black body of Yatagaramon gives him a wicked sight to behold, but many are informed that this Digimon is chosen as the guardian to a city called "El Dorado" somewhere within the Easten parts of the Digital World, and will lead anyone to it. The Eastern parts of the Digital World are still mysterious; what is known about "El Dorado" is that is protected with several sacred barriers. Some say that this is to protect evildoers from attacking, and that you can only get to "El Dorado" via Yatagaramon's permission if you pass his "Triple Tests", or so the rumour goes; those who fail the tests are sent to the Dark Area. He has the "Dokkosho" on both wings.

Attacks  Variations / Subspecies 
 * Mikafutsu no Kami (甕布都神): Channels the energy produced in the Dokkosho on his wings to his third leg and fires. The Digimon who experience this technique are completely broken down into pixels.
 * Haguro (羽黒, lit. "Feather-black"): Converts his surroundings to the dark of night for 3 kilometers with the black light that is emitted from his jet black wings.
 * Yatagaramon (new design)

Crowmon (New)
This new design is slightly different in the tips of his wings, the shape of his Dokkosho and the color of his claws. His evil image is now weaker. He is also known as Crowmon (Subspecies).
