"Tenshinhan, who is much stronger than “Fighting God” Master Roshi, is severely beaten by Piccolo’s henchman Drum, who Goku kills instantly and, after training for 8 years, becomes about as strong as Piccolo, who together just barely beat Raditz, who is about the same power level of a Saibaiman, who’re killed instantly by Tenshinhan and Piccolo, but who both don’t stand a chance against Nappa, who is beaten by a powered-up Goku, who must face off against a Vegeta who’s twice as strong, has powered up considerably, and still can’t even faze Recoome, who Goku kills in one hit, but still can’t face up to the four forms of Freeza, who, though a lot stronger, is cut to pieces by Trunks using half his power level, but who is actually just a fly when compared to Android #17 and, though actually nothing compared to Android #16, is still sucked up and used as a power-up for Cell, who is treated like a baby by Vegeta after having trained for a year in the Room of Spirit and Time, but who has the tables turned on him after Cell absorbs Android #18 and becomes unstoppable, who then is simply manhandled by an enraged Gohan, who Vegeta then passes in strength but still can’t defeat Majin Boo, who is about as strong as Gotenks, and not as strong as an awakened Gohan, but who’s still not as strong as Majin Boo after having sucked up Piccolo and Gotenks, is completely dominated, even after having absorbed Gohan, by the almighty Vegetto. That should clear it up for you."
