Auto-tether from edge

[ForteX]

I don't have a video because I'm a moron, and I haven't been able to replicate this, but I need to know if anyone else has ever pulled it off.

Story time:
I played some friendlies before a tournament just yesterday, and decided to test my Lucas vs Sonic matchup. While playing keep-away with Rope Snake near the ledge, Rope Snake just sort of flopped and immediately grabbed ledge. The closest thing I can compare it to is ZSS's tether tricks.

I don't believe I input anything out of the usual zair, and I went back and tried it a little later to no avail. No matter how close to the ground I zair'd, I never got the same result. There must be some kind of additional input I didn't know I was doing. I'll be spending some more time in the lab tomorrow to see if I can replicate it and record the footage, but until then, just putting this out there, because if it can be done with any form of consistency, it's all but a guaranteed ledge trump into bair spike.

As with most things, I'm fairly certain I didn't discover this tech, but since there's not a thread on it, I just had to ask.

I can confirm I also had his strange occurrence. Did he pop back kinda awkwardly? Like the animation was just strange? I did while on the actual stage and also have not been able to replicate it

That's a RAR Z-air.Short-hop back and press Z-air ASAP and Lucas should be grabbing the ledge with his tether.
This is extremely useful because B-air is 100% guaranteed after a tether trump.
