You can tech ZSS dthrow (labbing ZSS dthrow weirdness)

In fact to tech it you have to tech it twice https://streamable.com/06iua.

For some reason in ZSS' dthrow she first does a meteor hit that is entirely normal, except 4 frames into it the actual throw takes over, even overriding any tech you can do. This hit usually hits you into the ground immediately but if you are at the edge of a platform/stage then it actually changes where the dthrow will release.

To get the tech in the original tech i had to DI in to get a walltech, then use the tech walljump animation to get far enough into stage that i can tech the second part (using the same original tech input since it lasts long enough for it)

You can even tech the throw normally except since its overridden it doesnt actually change anything https://streamable.com/mxggq

This hit also just makes the throw release really low if it doesnt hit anything so stuff like this exists on DI in. https://streamable.com/zubgl

(i always thought the low down release was because the move had a low release point or something, not that it actually spikes you before it does the real throw)
