Story: Donte has sweared to Armstrong saying "f*** you". Armstrong becomes very pissed off and starts charging his "Nanomachines Son" by draining energy from nearby vehicles and machines, making them levitate in air and exploding them in progress. Donte starts clapping his hands just like Sam and points his Ebony&Ivory to Armstrong...
Armstrong has his "Nanomachines Son" at full power and can use the nearby vehicles(car, choppers, bike, etc) to launch against Donte.
Donte has his Rebellion(all forms inclued), Ebony&Ivory and can use his Devil Trigger.
They fights in the downtown of Denver.
If this is a "spite" in Armstrong's favor add DmC(not DMC) Vergil to help Donte, if Armstrong still stomps add DmC Mundus to help them.
already played new dmc. donte is weak compared to the original dante. he also need help from vergil to destroy mundus. but as far i know donte is pretty agile. maybe with hax and speed donte have a change to beat senator.
