Nope. I was crushed that he didn't make it T_T. Well Olimar is directly from Nintendo, technically Joe is third party.
Joe, King Krul, and of course Megaman were all hoped to be in it. Sadly, Joe is NOT a first party game despite many seeing him as a nintedo char, he has appeared more on Sony systems and has had extras on Sony systems(true Snake did too, but capcom does not admrie nintendo like Kojima does). King Krul would have been much more appreciated than Dedede and is a much more popular char, sadly Nintendo disagreed and thought Kirby needed three characters more than DK did. Megaman first appeared on Nintendo and still has many Nintendo exclsuives, I have no clue as to why he wouldn't make it in, personally I believe Nintendo didn't try to get him. And Olimar was in it becuase Pikmin is a popular and fun game.
I thought he'd be cool, but yeah if controlled time it would be too chaotic unless it was a final smash, I suppose
