Iwata: Speaking of which, Isaac is not present as an assist trophy this time.
Sakurai: Ah, yes, about that.
Sakurai: See, when Brawl was created, one particular number of the staff programmed him in without my consent.
Iwata: *laughs* I see. He must have been very dedicated.
Sakurai: Yes. But on this game, he was no longer on the team.
Sakurai: I had asked the team who exactly Isaac was, so I could put him in the new game, but nobody knew. Isaac must have been some original character or something.
