|Captain Marvel Adventures #46 (Note that Mr. Mind was placed in a museum!)|
Captain Marvel met Mr. Mind again in Shazam! #9 (October 18, 1973) in the story, "Worms of the World, Unite!" At the end of the story Cap asks, "Mr. Mind, how did you survive the electric chair?" Mr. Mind's responded with, "Would you believe a segment of me broke off and I regenerated my body?" Cap doesn't believe him and Mind promises to tell him another explanation the next time they meet!
We finally get the answer to the mystery in the story, "The Rainbow Squad" in Shazam! #31 (June 9, 1977). Captain Marvel has captured Mr. Mind once again and asks him directly, "Just one question - and this time I want an answer! I captured you - you were tried - found guilty of 186,744 murders - and you were executed in the electric chair! How did you survive?" This time, Mr. Mind gives the true story of how he survived the electric chair. Mr. Mind replies, "You forget - I'm an alien! My race is immune to electric shock! It doesn't kill us - only puts us into suspended animation!" Mind further explained that when he revived he found himself in the taxidermist shop and hypnotized the taxidermist into making a fake worm and letting Mr. Mind go!
The conundrum of Mr. Mind's mysterious return has been solved!
