Genesect is possible, but I was referring to Gen 6 specifically. Because most of the generations of Pokemon have had a specific Pokemon we'll call the "Bipedal Badass."
Mewtwo, Lucario, Zoroark, Genesect all fit under that. Genesect not as much as Zoroark, but he's definitely more popular so I digress. These Pokemon were all heavily marketed. Lucario and Zoroark specifically were the first Pokemon shown of their respective gens.
Gen 6 doesn't have any Pokemon like that. They didn't make a new Pokemon to market like that. Instead, Mewtwo made a comeback. He is basically the "Bipedal Badass" of Gen 6, because he was marketed just as Lucario and the rest were.
