Raditz enters the room you both shared, he came to wake you up because he wanted to spar. You had beat him last time, and bruised his ego.

“Get up, I want a rematch!” Raditz demanded, grabbing your shoulder and shaking you. He wanted to restore his ego, you had thoroughly showed him how capable you were. You always seemed to beat him somehow, and he hated it.

Raditz was like your friend…sorta. He was egotistical and liked to prove his strength.
