Can Dedede 2-Framing abilities

[Alsyght]

I know Down Smash and D-tilt can catch 2-frames, but what about his back air and the back of his Up-Smash? I’ve tried to but I’m not that good so I haven’t had any results so I came here to ask.

just Dash attack If you want to 2 frame
the move is ****ing HUGE and KO's at the ledge ridiculously early (think 60-70 ish) and lingers for a long time.
