|Prior forms||Manticoremon + Shinedramon|
Thorndramon is the resulting fusion of the extremely deteriorated viral data of Manticoremon and the curative vaccine data of Shinedramon. The fusing of the two vastly different Digi-Cores resulted in a splintering of Thorndramon's fractal code, which causes it to swing from extreme evil to extreme virtue. It is a great and terrible force, known to many as "The Thorn of Night".
Thorndramon has four great wings that have white spokes and black wing leather. The body is covered in White Digizoid trimmed with Black Digizoid, with spikes of Black Digizoid running down its back. Its talons are also made of Black Digizoid. Its eyes are a deep green, but can change between red (enraged) and gold (joyous).
