So I think I figured out how this can combine with the main donbrothers mecha
THIS IS JUST MY THOUGHTS NOTHING HAS BEEN RELEASED YET IF THIS EVEN CAN COMBINE
The gold arms of this mecha connects to the feet of the main mech (as the arms have those dragon feet as well as connecting tabs on the side)
The gold chest plate replaces the chest plate of the main mecha
The dragon head replaces the helmet of the main mecha
Then the gold legs and wolf somehow combine together to create a backpack/maybe wings by connecting to the butt of the main mecha
