When he saw Wukong become a Saiyan, he was very scared.
He exerted his strength to the extreme, but his strength was not as strong as Wukong's.
His energy is still losing. He tried to kill Wukong with Kling's true qi, but he was torn by his own true qi.
Finally, he turned to Wukong for help, and the kind Wukong gave him some energy. He gave Wukong, who had already flown far away, an untimely blow. After Wukong found out, Wukong changed to blow. Kill him. He and Namik exploded.
But he's not dead. His body drifted in the universe and was found by his father and brought back to Frisa. Restoration turned him into a semi-mechanized Frisa, who came to the earth with his father and his men. I met Nanques from the future on the earth and wanted to compete with the future Nanques, but I didn't expect to be split in two. Frisa's father was also killed.
Don't go into details, just go and see Dragon Ball Z yourself.
