KILLIN' INSTINC
Vegeta was beating up the regular bad guy as he does normally. Vegeta merely tripped him and punched him right in the stomach. He did it so hard that the robber regurgetated blood. After the cops came, Vegeta flew away feeling relieved because he is doing good while fighting at the same time. As he was flying over the police car he got a feeling from the back of his mind. "Final Shine Attack!" screamed Vegeta blowing up the Police car. After noticing what he did he flew away so he won't be seen. He couldn't remember anything. As he was flying, he saw a law being broken. A man was beating his wife. Again Vegeta got a feeling. "Big Bang Attack!" Vegeta not only killed the man but also killed the woman he was beating. He then heard a voice saying, "I'm in control now!" Vegeta's eye's turned plain white. He then looked at a city and grinned.
Trunks was hanging out with Goten talking about how he almost died saving Pan. Before he could finish his sentence he sensed an evil but familiar KI. He told Goten to go home, that'll he take care of this.
Trunks was flying through the sky searching for this KI and finally came to the conclusion that it is his father. When trunks reached his father, first he tried reasoning with his father but Vegeta only punched him in his stomach. Trunks then knew there could only be one way to save the city. Trunks immediately attacked his father with a dropkick. This only made Vegeta lose his stance and the fight was on.
Vegeta capitalized immediately. He kneed his son in the stomach and delivered an uppercut. This knocked Trunks almost into orbit if Vegeta did not appear and elbow dropped him back onto the earth. Vegeta grabbed him by the neck and slammed him through walls. He then sent trunks flying when he punched him while he through a KI ATTACK. Then kicked him to the ground followed by a falling knee drop to Trunks's stomach. Trunks started to spit out blood and new now there was no chance of winning against his father but stood up anyway. Vegeta then grabbed Trunks by the hair, lifted him up and used him as a punching bag. Trunks then noticed that even though he was Super Sayion, Vegeta wasn't. He then heard two people yelling KAMEHAMEHA. It was Gohan and Goten.
Vegeta then thought it was a good time to turn Super Sayion but couldn't. Something wouldn't. It was the real Vegeta. He then told everybody to run. Trunks said that he wouldn't abandon him and stood with his father. His father was self-destructing. Trunks took a death hold on his father. He wouldn't let go. His father was about to blow up but became unconciuse before he could. Trunks then started to beat up his father. He gave him lefts and rights. He sent him every KI ATTACK he knows until he saw a shadow ghost float away from him. Trunks saved his father from evil and death.
