A Tremendous Betrayal

Chapter 1: Training

~Trunks POV~

"Boy. Get up. You will be training today."

Vegeta. My father. Great. Lovely way to start out my morning. I groaned and rolled over, pretending I hadn't heard my father speak. This turned out to be a mistake, which I realized when I felt freezing water poured on my face. I sprang up and yelled:

"Did you have to do that?" Why do I even bother asking?

"You don't ignore me and get away with it, brat. Get dressed and meet me in the gravity room in ten minutes. If you are late, you will regret it." My father spoke, monotone as usual.

"Dad. It's 4:30 a.m." I stated.

"Your point... being?" He asked. I groaned once again. I knew I had fallen behind on my training, but my father hadn't bothered me too much about it... I should have expected that the peace wouldn't last.

"People tend to enjoy sleeping at this hour." I replied, and immediately regretted it. My fathers eyes immediately hardened, and while his next reply was calm, it was cold enough to send a chill up anyone's spine.

"The business of others does not concern me. You will get dressed and you will join me in the gravitational chamber. Right now." Arguing with my father would be pointless.

"Fine. You win." I grumbled. To avoid seeing my fathers victorious smirk, I quickly got out of bed, turned away, and said, "I'll meet you in the chamber in ten minutes." I heard my father leaving the room, so I got dressed in my usual training attire and dragged myself to the gravity chamber. The moment I stepped into the room, a punch was thrown at my face. I was surprised, but managed to avoid the punch. My father began to attack ruthlessly, and I quickly realized that he would not be going easy today. I continued to dodge his attacks and counter them with my own. Every time I made a mistake or was hit by an attack, father would yell about how weak and useless I was. Not what I wanted to hear, to say the least. Eventually, I became fed up with this training "system" and blew my top. As my father attempted to punch me from the left, leaving his face exposed, I rammed my fist into his face, sending the Prince of Saiyajins flying into a wall.

"Enough!" I screamed. "I refuse to put up with your insults another moment!" With that, ignoring the cold expression on my fathers face, I stomped out of the gravity chamber, fuming, only to come face to face with my mother. Quickly, I put on a fake smile.

"Good morning mother!" I say cheerfully. "What brings you here?"

"Well, originally I came to call you two to breakfast... Your father forced you to train, didn't he?" My mother asked. Oops... apparently my earlier facial expression hadn't switched swiftly enough.

"Oh, it's nothing mother! Don't worry about it!" I assured her. I could see she wouldn't give up that easily. My mother was a stubborn woman. Attempting to change the subject, I said, "So, you said something about breakfast?"

"Yes." She answered. "Vegeta, come on! Breakfast is served!" Bulma called over my shoulder. Father didn't need to be told twice. Any mention of food immediately snaps him out of training. Grumbling something inaudible, father brushed by mother and myself. I sighed, and walked after him, leaving my mother frowning at us as we walked away.

~Later at Breakfast (9 a.m)~

The silence was so tense that it could probably have been cut with a knife. As we ate, I watched mother staring intently at my father, him pretending not to notice. After the fifth serving, my father silently rose from the table and started off to the gravitational chamber. Then, he stopped, and without turning his head said:

"Boy. Hurry up. Your training session has not been completed yet."

"Father, but..." I started to counter, but he cut me off.

"Do not dare but me. If you can not bare a bit of training, then you do not deserve to call yourself a saiyajin, nor claim the title of my son."

"Vegeta!" Mother intervened. "Don't you dare say that to our son! He has trained, leave him be for a while!"

"Woman, you understand nothing of training, a mere four hours of training is nothing for a saiyajin." Vegeta replied.

"He's 16! You can't expect him to..."

"To what? The brat has grown weak and soft since Buu has been defeated." Father said, shooting a disgusted glare at me. "What is he going to do when the next threat shows up? Let Kakarots brats do all the work? I think not." By this point, I had heard enough. I stood up and walked out of the house, taking off into the air.

"T-Trunks wait!" Mother yelled after me, but I ignored her. Soon enough I was out of ear shot. I flew off in the direction of Goten's house, intending to stay there until I, and hopefully my father cooled off. Little did I know, I was being watched.

"Hmm... Interesting, this one. This little situation has potential... I ought to keep an eye on the boy..."
