The morning struck and Vegeta was preparing to go look for the person the crippled him for a few hours. They had moved Goku back to his house where Chi Chi and Gohan were taking care of him while he's in his frozen state. As much as Vegeta didn't want to admit it, he wasn't going to try and prove to be stronger and be cautious so he doesn't slip up again. His pride had already been hurt. He didn't need it hurt again.
Meanwhile, Y-17 was preparing to wipe out Vegeta. The doctor, thrilled with Y-17's success against such a powerful foe, decided he would further his research. He grabbed his things and came into Y-17's room.
"Are you ready to help me with something? If you don't want to, I'm sure your target would be happy to show up if you did." He said to Y-17. Y-17 looked up at him and nodded. The doctor jumped with glee. "Let's go then."
Y-17 and the doctor stepped out of their hidden facility. The hot sun shined on them. "Now let's go. I'm sure you can sense him. He was a failed experiment and he's deathly afraid of the heat." The doctor said. Y-17 sat down in the sand and almost instantly grabbed the doctor and ran towards the reading. The doctor was amazed at how great his experiment had turned out. He wanted to pinch himself to see if it was all a dream.
Y-17 reached a man that had an abnormal reading. Y-17 went up to the man and punched him. The man flew across the desert and laid there knocked out. The doctor fell over laughing. "That's not him. That's the so-called champion of Earth Mr. Satan." He said. Y-17 looked for another reading and found another one. It found a man sitting in the shade. His reading wasn't high enough to be dangerous, but there was something that bothered Y-17.
Y-17 went over and punched him. Its hand went through the man's head. Y-17 punched him again, but this time in his stomach. The same result. The man then stood up and punched Y-17. Y-17 went flying backwards, but was able to land on its feet. The doctor was intrigued. "So he can liquefy and solidify his body. That's what you need to keep in mind Y-17." He said. Y-17 nodded. It ran back at him and started throwing a multitude of punches, but all going through this man.
The man then threw a punch at it. Y-17 caught it. In response to it catching it the man liquefied his arm, then solidified it to trap Y-17, punched it and liquefied his hand again to send Y-17 flying. The doctor was losing hope. "Focus Y-17! Don't let this idiot beat you!" He yelled. Y-17 attacked again, but this time it attacked with its whole body. The man solidified his entire body to try to stop Y-17 in its tracks. Y-17 instead slowed down and picked up and threw the man out of the shade. The man panicked and screamed. His body started to rapidly dissolve in the sunlight. He tried to liquefy in a panic and instead dissolved completely before he could reach the shade again. "Good job." The doctor said as Y-17 walked away from the battle scene victorious and ready to go home.
