More information on Tyrannomon has been revealed in Digimon World Re:Digitize Decode. In addition to gaining a final form, Tyrannomon is an actual character from what appears to be a quest.
Tyrannomon and the protagonist meet when the player catches the Digimon rifling through the Meat Fields at night. Seeing the error in his gluttonous ways, Tyrannomon sets off on a journey to grow stronger. Over time, the Tyrannomon evolves into MetalTyrannomon, and finally, into RustTyrannomon.
RustTyrannomon, a virus-type that evolved from a MetalTyrannomon that survived through the harsh battles and severe environment that followed the creation of the Digital World, causing its body to be covered in red rust. It specializes in annihilating its opponent, and one is enough to level the enemy and everything surrounding it.
More information has been released on the new DoReMiFa Lodge as well. The lodge is an apartment complex where you let the Digimon you recruited live. You can choose whatever Digimon you want to live in the apartments.
As the lodge’s landlord, it’s your task to fill up the empty rooms and expand the mansion as well as collect rent. Events will also happen in the apartments, and fulfilling these expands the number of rooms you have.
Digimon World Re:Digitize Decode will be released in Japan on June 27, 2013.
