Prologue:
3rd Dimension:
D-Phineas looked out of the window of the government building that he and Ferb built to the beautiful blue skies. They had come a long way from a city of ruins, now the old city was a thriving metropolis. There was a giant wall around the city to prevent invaders along with guard towers. Inside the city citizens enjoyed their normal lives once again. Yes everything was back to normal and D-Phineas and D-Ferb ran the city along with the military base outside the city.
"You know what Ferb, I am glad the war is over now I have time to take Isabella out on dates and not worry about killer robots," sighed Phineas as he watched the sun rise.
"I agree this is the golden of our civilization," replied D-Ferb as he stood next to his step-brother. Suddenly they were interrupted by a large explosion near the front gates.
"Sergeant, status report," said D-Phineas into the radio.
"The entrance is damaged but it will hold also a large number of unknown hostiles are heading towards the city," replied the sergeant.
"Copy that it must be Roger's army, prepare the men and move all of the women and children to the military base by helicopter, I want all able male civilians loaded up and ready to fight within five minutes!" ordered D-Phineas.
"Yes sir!" answered the sergeant.
"Ok Ferb sound the alarm!" shouted D-Phineas as he got suited up. D-Ferb pushed a red button and alarms blared across the city as civilians ran towards the evacuation helicopters and the soldiers ran towards the entrance gate.
"All forces prepare for battle seal off the city this is not a drill, repeat prepare for war!" shouted D-Phineas into the radio.
"Come on bro let's finish this," said D-Phineas as he ran towards the front gate with Ferb right behind him.
"Ok that's my prologue and a cliffhanger to go with it. It's good to be back! Sorry it was short but I hope you all enjoyed this prologue and I will update this story as fast as possible. Also this is a sequel to Journey into the 3rd Dimension so you should read that story first before you read this one. So will D-Phineas and D-Ferb lose the city? What do Rogers new robots look like? What is Roger's plan? Will Roger finally win? Sorry for all the questions but anyway find out in the chapters to come."
P.S. I do not own Phineas and Ferb or any of the characters mentioned in this story. The plot of this story is mine though.
