So I've been playing ssf2 for a while now, and I never really realized this because I usually play characters that make it near impossible to experience, but recently, in my matchup against Yoshi as Link on Battlefield, I noticed a lot of hits registering but not dealing any knockback to Yoshi. Are phantom hits in ssf2?

I don't think phantoms exist in this game. Maybe what you're talking about is super-armor? Yoshi has "super-armor" during his double-jump. During the jump he takes damage but not knockback if he gets hit.

I'm not 100% sure, but I'll replay the clip I have to see if all the hits I claim were phantom hits happened during his second jump.

So Yoshi's super armor even protects him from nairs and bombs (link)? Even Link's up-b? What doesn't it protect?

Also does Mega Man also have super armor while doing his recovery move?

Yes, Yoshi's super armor protects against all those attacks. A certain amount of damage will break the super armor. Some characters' spiking moves will cancel it, for example. Idk about Mega Man having it. Never really played him. (Sorry about the late reply. I missed the notifications for your replies.)

It's fine. We all have important things to do irl. Thanks for responding.
