When using Gouie’s ledge special, there seems to be a significant gap between the startup intangible frames and when the hitbox comes out. About 7 frames gap. Even when buffering right after grabbing ledge (so ledge intangibility carries over), there is still about a 4 frame gap. I checked a handful of other characters’ ledge specials and I noticed their hitbox always at least comes out the same frame the intangibility ends.
Those other characters can at least trade if the hit/hurtboxes overlap, but Gouie always seems to lose. There is no superarmor during these frames as well. In fact, Etalus has a similar ledge special as Gouie but Etalus remains intangible for the first few frames even after the hitbox comes out.
Are these intended? Seems strange since other characters at least have intangibility until the hitbox comes out. I would understand if Gouie at least kept his super armor during the start up, but he doesn’t.
I would love to be able to use this as a edge guard tool, similar to how clairens or la reinas use their ledge special, but it always loses to any recovery move. It also loses to people preemptively attacking the ledge option where most other characters’ get up special would punish that.
1st image is the first frame of vulnerability after using ledge speical. 2nd image is the first frame the hitbox comes out.

Most if not all ledge specials lose their intangibility before the hitbox comes out. For Etalus there’s a 10+ frames window of vulnerability
