At the end of the film, it is seen that he and Ralph have made ammends, and in the tie-in comic 'Wrecking Party', the two even seem to become friends.
On the 30th anniversary of their game, Gene, Felix, and the Nicelanders are celebrating in the penthouse, along with many video game characters such as Sonic and Pac-Man. Just then, Gene answers the door, believing it to be another guest. Instead, he finds Ralph. Gene warns the others who fear Ralph will wreck the party. They tell Felix to send him off, but the bashful hero indirectly invites him in. When the furious Gene begins to ostracize Ralph, the bad-guy quickly begins to lose his temper. Ralph asks Gene if winning a medal will earn him respect, and Gene declares that if he won a medal, the entire penthouse would be handed over to him. Gene then declares that Ralph winning a medal would never occur anyway because he's just the bad-guy who wrecks the building, causing Ralph to crush the cake in anger, proving Gene right. The bad-guy then leaves the party to find and earn a medal.

Gene then gathers his belongings and heads out, handing over the keys to the penthouse over to Ralph, as promised.
