I stand by my earlier posts. The fight could go like this, if it takes place in a city
Colossus powers up to Colossonaut and engages DD in a fist fight. Cyclops blasts DDwith his optic beams while Magneto manipulates several cars into a blades to stab into DD. With DD preoccupied with several attacks, Rogue then sneaks in and touches DD, taking on hi power. The combination of Colossonaut and DD powered Rogue is enough to KO DD.
