While it came out in Smash 4, I was glad to see this jetpack return. It’s from the Pilotwings series, which isn’t my cup of tea.
But I do like it as an item. It doesn’t really have any power or attack to it.
But you can fly up in the air and way above your enemies’ heads.
Which makes it very handy, especially if you get knocked near the edge of a stage and you’d probably never make it with your warrior’s recover skills alone.
