You begin a dual with Cell. You give it your all but he just keeps on counter attacking you. I mean, he does have the DNA of you, Piccolo, Vegeta, and Freeza. So, knowing you can’t beat Cell, you call in your son Gohan to help you. He miraculously turns Super Saiya-jin 2 and finishes off Cell easily by blasting him into the sun with the famous Kamehameha.
Look, it's a dragonball that regenerated from Cells last Cell. Now you only have one more dragonball to get and you can make your wish. I hope your body can hold that energy you posess, cause it is high.
