Forward smash question

[pacha]

So during forward smash, from frame 22-25, charizard is invincible.

My question is does that invincibility extend for the duration of hitstun if attacks clash?

This would be good to know in a dubs or 2 on 1 situation to weigh the safety of the option. If you could get 15 (or so) extra frames of invincibility that could be nice.

I'm pretty sure it does while you are in hitstop, when you F-smash a Smart Bomb you stay invincible for longer then 5 frames.

I would think if your attack clanked it would stop the invincibility as it resets you to standing animation.
