Tales of Suspense #83

Iron Man frees Pepper from the Titanium Man's paralysis beam and then goes on to defeat him on live TV. A final, deafening blast from Titanium Man's beam restores Happy's memory. Titanium Man flies off to his supposed rendezvous with the submarine but is abandoned by his masters before he gets there and is left to languish in the ocean. Iron Man is a hero, and even Senator Byrd is rooting for him. When Tony Stark appears Pepper hugs him; she seems to have forgiven him for his recent seeming transgressions. Happy, memory intact, now knows the truth, that Stark is Iron Man.
