A lot of trouble
One day, The Master decided to give a present to the Road Rovers, because it was Christmas.
"Thanks very much Master. Colleen, would you like to open it?"
"Sure Huntie!"
However, when she opened the box, a mad-scientist eagle got out and started to cause havoc throw the world.
"What kind of stupid present is this?" asked Blitz, now very angry.
"I thought you would like to have some exercise, since there are no more bad guys to defeat."
"When we solve this, we will kill you!"
"Come on Blitz, you don't need to be over-reacted!" said Hunter.
While the Road Rovers prepared themselves to their new mission, the eagle (which was called Emil Eagle) went to the Rocky Mountains and opened a bag that he brought with him, and out of it came a full-built lab! Meanwhile, the Road Rovers traveled all over the world in search of this new villain, until they ended up in Emil's lab. Then, a cage felt and they got trapped.
"Welcome, canines-which-I-don't-know-the-names. I'm Emil Eagle, and you're probably wandering what is my evil plan. Well, since I like to cause plot-dump, I will tell you that I want to create an army of "ugly things" so I will make the Earth an ugly place!"
Then he started to laugh in a megalomaniacal way, until he started to cough. Anyway, the Road Rovers thought Emil's plan was stupid, and should be he.
"If you want to make the world an ugly place, why don't you let us show you how to make things ugly?" asked Hunter.
Emil Eagle agreed and released them, only to discover that they lied and he ended up cooked. As for The Master, well, he was forced to be a toilet cleaner during ten years by the Road Rovers.
The End
