Peace is never a certainty. There is always going to be someone who is acting in violence. However, in context, for the Z Warriors, there had been peace for four years now. Violence to them was something trying to destroy the Earth. Last time this happened, the evil android Cell was trying to destroy the Earth. Last time this happened, he was beaten by Gohan, the son of Goku.
The Earth was not in danger, and the Z warriors had all but given up training. At this time, they led their own respective lives. Gohan was having a steady relationship with Videl, and was doing well in school. Piccolo mostly meditated, and Vegeta, was, Vegeta.
However, peace could be shattered like a piece of glass. Like a piece of shattered glass, the shards would fall, and someone would get cut. What is most unlikely, however, was that the person protecting the glass would be the one to shatter it.
Piccolo was mediating atop of Dende's lookout. Floating near the edge, his aura became bright, and fell, in time with his breathing. It was like a metronome, rising, and falling with every beat, for the music of energy to flow through his body. Ever watchful over the events of his friends, he was like the bodyguard of the Earth. Always making sure the wrong people stayed outside on the curb, with their dirty trainers, and bad attitude.
During this dreamless, and powerful stage of time, Piccolo sensed something. It was a power level. He had never felt something that strong. Gohan was not as powerful as this. What was going on?
Piccolo came out of his meditation. Rather than in forming Dende, he would rather tell Gohan, and the other Z warriors. They could have a more immediate effect on this problem than Dende could. Anyway, they would all be coming here anyway, and Dende would probably already know.
Piccolo zoomed of into the distance, leaving a trail of smoke behind him, and Mr. Popo astounded by his rude exit. This wasn't Piccolo's normal attitude, but this was serious. Even from the distance he sensed, it was far more powerful than Gohan. Piccolo's first thought was to go to Master Roshi's, but on the other hand, he needed to tell Gohan immediately. He would be the Earth's only hope if this turned bad. So he headed to Chi Chi's home, to meet with Gohan, and to eventually meet with the other Z warriors.
Within a matter of minutes, Piccolo was outside the home of Gohan, Chi Chi, and Goten. In midair he screeched to a halt outside the quaint, but loving home. Chi Chi, dressed in her nice yellow outfit. *I can't remember what the thing is called! * She looked rather agitated, and not in the mood for chitchat. Goten was slowly, but surely crawling out of the front door. *I think I messed up time zones. Gohan is in school, and seeing Videl, plus Goten is still a baby. *
"Why hello Piccolo. What a lovely time to drop by and pay a visit." Said Chi Chi, sarcastic and rude, which further implied her agitation.
"I don't have time for sarcastic comments, Chi Chi. I need to speak with Gohan NOW!" bellowed Piccolo, with his usual general like manner of speaking. Chi Chi was, like Mr. Popo, shocked by his rudeness. However, knowing Piccolo, he had a reason for it. "Better not mess with him!" She thought to herself.
"Gohan is at Roshi's with the rest of the gang." Answered Chi Chi. She was about to say how surprised he would be to see you, but Piccolo had already left, his aura glowing behind him.

Over at Master Roshi's, the gang was relaxing as ever. Master Roshi was chilling on a chair, with his trademark magazine on his chest. Vegeta was teaching Trunks something. As for Gohan, he was having a pretend battle with Tien, and Krillin. All seemed well for them until they felt two power levels. One was obviously Piccolo, but the other was so unusually powerful, they were scared of it. Suddenly, the aura of Piccolo began to appear in the distance. The gang looked up to greet him, just as he arrived.
"Hey Piccolo. What's wrong?" Asked Gohan, with a concerned look on his face. He looked at Piccolo. He was nervous, agitated, and what looked like FEARFUL!
"No time for greetings, Gohan. Something is headed for Ear..." Piccolo didn't finish the sentence. He seemed to enter a hypnotic trance. His eyes changed from black to red. His power level increased dramatically. He raised his hand slowly, his palm facing toward the home of Master Roshi. The gang didn't realize what was going on, but Gohan knew well enough what to do. Gohan came into the path of Piccolo, trying to save Roshi's home.
Piccolo fired the blast. This blast, Gohan would have normally knocked away from them with ease, came with such power, that he had only enough time to dodge the blast, not block. The Z Warriors scattered from the scene, including Vegeta. He realized the ferocity of the attack, and literally threw Trunks from the scene of the blast. The energy ball ripped a hole clean through Roshi's house, leaving the other side, before delving into the depths of the ocean, causing waves to splash 50 feet into the sky, before dropping with a deafening crash. Piccolo gave a grim smile, before turning, and shooting off into the distance with incredible speed, disappearing along with that power level.

The dust cleared from the scene. Roshi, who was closest to the blast, was covered in dust, splints of wood, and plaster particles. A couple of people coughed, but all were fine. Most looked confused, but Vegeta looked unhappy at the rest of the group!
"I told you we shouldn't have trusted the Nameks. Look what he has done to us. I knew I should have killed him when I had the chance. I would have loved to rip his antennae off and shoved them up his..." Vegeta roared before being stopped by Gohan.
"Listen, Vegeta. That was not Piccolo. Well, it was, but he was being controlled by something. We all felt that power level and we all know that was too powerful to be something natural. That is what was controlling Piccolo. And if that was being controlled, we are gonna need some help!"
