Obsidian seemed to just lay there and take the punishment from all the attacks when MechaGarurumon finally planned to finish it. "Go ahead. I'm an AI, I can hop to another machine if you destroy the armor. Hit too hard, however, and you CAN and WILL hurt Sapph, and I'm sure you don't want that!" He said. If he had a face, Obsidian would be smugly grinning at this point. "Though, I'm not really interested in giving you the option to go through with it or back down." He said, the power source in his chest glowing brightly before firing a unibeam.

Pumpmon made it back to the fight with the 'gem in tow. "Alright! Now we can end this!" He shouted, the gem he was carrying glowing brightly before shattering into 3 balls of light, each going into one of the digimon, who then proceeded to change.
"Rize Greymon Evolve!"
"Paildramon Evolve!"
"Pumpmon Evolve!"
The three digimon were consumed by light, which faded to reveal their new, Ultimate forms.
"Victory Greymon!"
"Imperialdramon!"
"Beelzebumon!"
Now in their final forms, the 3 digimon were ready to finish off Null2.
(Pumpmon > Beelzebumon, Rize Greymon > Victory Greymon, Paildramon > Imperialdramon.)
