Jeff Kaplan, vice president at Blizzard Entertainment and lead director of Overwatch, is quite emphatic about letting Nintendo and the Super Smash Bros. Ultimate development team use “whatever character” from Overwatch they’d like.
Speaking to IGN in a recent interview, Kaplan said, when asked what Overwatch character he’d like to see guest-star in Smash Bros. Ultimate: “To the Smash Brothers team, whatever character you want, we love them all. They’re all our babies, you can have any single one of them. We have 31 to choose from.”
