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
Sorry, I must’ve buffered from ledge so the intangiblity overlapped. But when I tested again for Etalus there was only 2 frames of vulnerability with no carry-over ledge intangibility. When special is buffered from ledge, it’s 8 frames of hitbox and intangibility overlap. I’m not getting your numbers.
I decided to test all the characters with and without carrying over ledge grab intangibility (hung there until it ran out, then pressed special):
The first number is without carrying over any ledge intangibility and the parenthesis number is frame-perfect ledge special after ledge hang. A positive number is the number of frames gap after becoming vulnerable and before a hitbox comes out. A negative number is the number of frames while still invulenerable after a hitbox came out.
Forsburn: 1 (1) frame
Loxodont: 0 (0) frames
Clarien: 0 (0) frames
Zetterburn: 0 (0) frames
Wrastor: -5 (-5) frames (but he’s in the air so its kinda different)
Fleet: 0 (0) frames
Absa: 0 (-5) frames
La Reina: 1 (0) frame
Galvan: 2 (1) frames
Olympia: 6 (6) frames
Maypul: N/A because doesn’t get off ledge
Kragg: 0 (0) frames
Ranno: 0 (0) frames
Orcane : 0 (-11) frames
Etalus: 2 (-8) frames
Slade: 2 (-9) frames
Gouie: 6 (3) frames
Most characters have perfect overlaps or 1-2 frames of vulnerability. Only Gouie and Olympia have “big” gaps. When buffering from ledge, some characters get a lot more intangibility, but both Gouie and Olympia remained very vulnerable.
1st image is Etalus without any carry-over ledge invulernability and 2nd image is Etalus with frame perfect carry-over ledge invulernability.

I think part of why Gouie has the vulnerable window before the hitboxes come out is because the active window has super armor, but I’ll pass this along and see if it’s something we want to change.

Looks like the info on wiki misled me
