- D-air (this seems to always hit the spike/meteor, but also seems to lack a hitbox on the 'arc' animation)
![Greninja :4greninja: :4greninja:](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
- D-air ( think this meteors/spikes, as well as popping people up? Someone correct me), U-air (explained below)
And yeah; those are the ones I'm aware of.
I missed some, obviously. Also, I read on the Greninja subforum that any multi-hit move with more than 3 hits will spike if you don't connect the last hit, and you are falling (or fast-falling, can't recall) when you deliver any hit that isn't the last (but has to be more than 3, I assume). Crappy explanation.
There's a video of it somewhere, but I can't find it cause the title is in Japanese. Maybe Sheik can do it too.
