Okay, I'll stop now. (Tetsujin 28 [Iron Being/Man two-eight] was originally from a 1956 manga, which later became a 1963 anime. I catalogued some information about Tetsujin here, and you can find intros for later series also based on the character here, here, and here. Yes, those are all different series. There also was apparently a live action movie, but the trailer looks disgraceful.)
-Signing off, and Merry Christmas Eve.
