And three DQs for you, too. (Is that everybody now?)
Huh? How exactly could Red Tornado be a copy of the Vision? Did Gardner Fox use a time machine? 
Silver age Red Tornado appeared in JLA #64 (Aug 1968), months before silver age Vision premiered in Avengers #57 (Oct 1968).
(Golden age Vision appeared in Nov 1940, the same month that Ma Hunkel first appeared as the Red Tornado… but that was published by Timely rather than Marvel so that wouldn’t work for this question phrasing, and those characters are not particularly similar.)
Correct on Reed.
#2 was Evil Roy Slade (as portrayed by John Astin in a TV movie)
#3 is Barbie Millicent Roberts, better known as just “Barbie”.
DQs:
- Best known from a movie?
- Protagonist?
Oops! Fact-checking indicates that my memory was faulty. (I probably read the Avengers comic before I read the JLA one). The Red Tornado did indeed marginally precede the Vision. So, withdraw my 2nd DQ above, please.
