Diablo Tank

"Diablo Tanks?! Oh no! The Nazi Union is shocked when the Diablo Tanks are made! Even for the Coalition of the Red Star! Oh God! Help me please! Have mercy on my soul!!!!"

--Su Ji-Hoon, The Big Battle

The Diablo Tank is an assault tank used by demons  and is an upgrade of a Tiger I.

They only use lava metal with some fire magic added on a captured Tiger I, and demons can build and create Diablo Tank named after a Spanish word diablo, when in the Demonic War.

They will fight for the Demonic Kingdom of Eeofol.
