Well, the story starts with two brothers, one wearing blue and another wearing gold and purple. The purple brother then uses a special mask in an attempt to ascend to godhood and reshape the world in his own image, forcing the blue brother to sacrifice himself to stop the other one. (Phantom Blood) Fast forward a long period of time and the evil brother has resurfaced and has assembled an army to try and take over the world, causing a group of quirky characters with unique colors and powers to then start a globetrotting quest to try and stop him. (Stardust Crusaders) Doesn't hurt that they have similar powers either. E.I. Tahu=Avdol, Lewa=Kakyoin/Joseph, Onua=Jotaro, Kopaka=Poleneraff/Jotaro, Pohatu=Iggy.
Now do you see my drift?
