3. Johnny Storm Was A Herald Of Galactus
One of Galactus' many visits to Earth saw him on the hunt for a group of alien survivors determined to hide planets from his notice. Through a complicated set of circumstances, Johnny ended up becoming Galactus' new herald. Thankfully, this was at a point in time where he had temporarily switched powers with the Invisible Woman (don't ask) - learning just how powerful his sister is, Johnny and the team later stopped the villain by transforming him into a human!
