|“You chose strangers over me?! Your creator?! Do your duties, Samurai! You will hear from me again, when the time is near!”|
|— The Empire Dragon|
The Empire Dragon (also known as the Unagami Black Dragon) is a mechanical dragon that Unagami can transform into, whenever he's angry or desires to threaten someone. It is one of the three shapes/forms that Unagami can adopt inside and, surprisingly, outside of Prime Empire.
Unagami finally opens the portal to Ninjago City but before he could leave, he is seen engaged in a fight with Jay, who only manages to delay him for a few seconds. Due to that, Unagami transforms into the Empire Dragon. After he defeated Jay, the Empire Dragon enters Ninjago.
After entering Ninjago, Unagami, as the Empire Dragon, engages in a fight with Jay and his Cyber Dragon all over Ninjago City, this leads them to the top of Borg Tower, where Unagami destroys the Cyber Dragon, leaving Jay only on his feet, on top of the helipad, there the Empire Dragon prepares to defeat Jay, but after Jay manages to calm him down through understanding and compassion, Unagami returns to his normal form to finally talk with his creator, Milton Dyer.
