Orin
for a non organic lifeform, the robot was pretty tough Orin thought. when the clone began to fire blasts of energy at which were stronger than the ones he had just shot at the robot, Orin charged up a great amount of energy in his staff and began to deflecting the blast by twirling his staff around at incredible speeds. he then charged at the clone, and using his free Orin shoved his palm out and shouted, "Pressure Palm!"
and when the palm of his hand made contact with the clone's chest, the invisible energy in his hand had went into the body and hit several mechanism. Orin's Pressure Palm technique used energy gathered up in his hands which would cause his foes to feel like they were being hit by the pressure of diving too deep into ocean without proper protection. on the outside the blow appears to do nothing but on the inside it deals damage internally. since his opponent was a robot, it required more power to do some real damage to the machine. so he dropped his staff and then proceeded to hit the robot many times with both of his palms, causing saver damage to the clone. After damaging its internal workings around the chest and abdomen area, Orin finished the robot off by jumping up and hitting the machine right in the head with his right palm. it caused the operating system in the machine's head to be crushed and the clone fell to floor dead.
Orin smiled at his work, he had done pretty for his try at training in heavy gravity so he decided that he needed more of a challenge. as he waited for another robot to come and replace the one he had ruin, Orin turned up the gravity to 29 times earth's gravity, and almost immediately felt the great stress at trying keep himself from falling over and stumbling about the area. this would much more difficult than before but he had to keep up with everyone else and push himself as hard as he could.
R'yak
the robot's movement was surprising and it took R'yak off guard and by the time R'yak noticed that the clone has reappeared behind him, it was too late. the blow was very painful and R'yak felt very dazed by the kick. the force of the attack had caused R'yak to fly forward and the machine then pummeled him with a hailstorm of punches and kicks. at this time R'yak had grown very annoyed of the clone and wanted to destroy the machine. before the robot could land another stream of punches, R'yak spun around and charged up energy in his Gravity-Repulser. just as the robot was about to land another punch to R'yak's face, he released a big wave of gravity which hit with enough force to shatter bricks and bend steel. the attack smashed the robot against the wall creating a big crater, and R'yak knew that this was his chance to finish the robot. he had the sharp talons come out of the fingertips on his Engergy-Gloves and he moved at insane speeds to the clone.
first he drove his left hand through the robot's chest and then he stabbed into its head. and with one massive heave, R'yak ripped off the robot clone's head. he was proud of himself for being able his enemy under such condition, but he needed to keep up his training and push himself even harder. so after he let the robot's head drop from his talons, R'yak upped the gravity to 25 times his planet's normal gravity. now he really felt the strain of training under such high gravity, but his resolve and will kept him determined to keep training and try to keep up with the Dark Saiyan.
