Note that the connections aren't primarily mine (I did reword them so it wasn't a copy-paste, though), but them again it's not like people own connections, so...

Cap wearing young protagonists from popular franchises who were born with a strange and powerful ability (PSI for Ninten and Star Platinum, Jotaro's Stand, for Jotaro) who go on a journey to stop a time-manipulating antagonist adopted into their great grandfather's family who returned to take over the world, or just to do some evil shit (Dio and Giygas). Their first appearance was also in 1989 (although Jojo itself started earlier).
