Once upon a time, long ago, the Saiyans were a warrior race used by Frieza to capture and eradicate planets so they could be resold to the highest bidder. Frieza, their commander, upon learning of a legend that involved a "Super-Saiyan" who would someday destroy him, concluded that it would be Prince Vegeta. So he manipulated King Vegeta into giving up his son to his authority. King Vegeta, however, didn't completely trust Lord Frieza and sent his best, most trustworthy man, General Nappa, along to protect the boy.
Nappa wasn't happy with the arrangement. He felt like a babysitter. He didn't dare complain though, as he was extremely loyal to his King. When it came time for his yearly physical, the doctor noticed he seemed to have pent up frustrations and advised him to keep a journal.
"What!?" Nappa growled, "You mean like with a pen and paper and all of that hullabaloo?" The doctor backed away from the giant soldier and swallowed. He then slowly nodded his head up and down to indicate that was indeed what he meant. He closed his eyes and waited for Nappa to kill him. "Okay then!" Nappa shrugged his shoulders and swaggered his massive frame out of the office. The doctor sat down at his desk and poured himself a drink from the whiskey bottle he kept in the bottom drawer.
Prince Vegeta was leaning on the wall with his arms crossed. "What took you so long?" He snapped as Nappa came strolling down the hallway. He didn't wait for an answer. He flipped his red cape over his shoulder and stomped off toward the training room. "Yeah, little buddy, I'll be there in a minute. I need to stop by the surplus room and get a few supplies, all right?" Prince Vegeta merely waved his hand at Nappa, not even bothering to look back at him. Nappa glared at the boy and shook his head in disgust.
Nappa hurried into the surplus room. There was a feeble little alien wearing the typical uniform and had round spectacles perched atop his odd-shaped nose. "General Nappa." he greeted. "What weapons will you and the Prince be needing today?" Nappa looked around and answered gruffly, "The usual… and uh… a pen. I need a pen." The alien looked at him in surprise. "Oh?" he began but Nappa rudely interrupted him, "and a notebook, you know, with paper in it." The elderly alien suppressed a smile. "Is the Prince interested in writing letters home?" he inquired carefully. Nappa just stared at him. The alien weakly smiled and quickly gathered everything for Nappa.
Later that night, Nappa showered and grabbed a drink. In one swift motion, he knocked everything that was stacked up on his desk off to the floor. He kicked several items out of the way then sat down and opened the notebook and clicked the pen. He stared at the paper for a few minutes trying to decide if he really wanted to do this or not. "Oh what the hell!" he growled out loud. If the doctor told him to do this then it would probably benefit him. So he leaned forward and began to write.
Entry 1101 - So, here I am, General of the Saiyan Army… I'm a tough guy, all-around, straight-up, bona fide bad ass… stuck on frickin' babysitting duty. This is bullshit! I seriously need to just destroy something. But nooooooo, this is my home planet, Planet Vegeta, under the rule of King Vegeta and I, the mighty Nappa, am stuck escorting Prince Vegeta around and training the little bastard. What's that smell? Oh yeah! Bullshit!
Nappa furiously slammed the notebook shut and flung aside the pen. He fold his arms and sulked for a minute before he realized that he did feel a little bit better now that he'd gotten that off his chest. He grinned. "That old doctor knows what he's talking about!" He laughed out loud. "Boy, I'm sure glad I didn't kill him!"
