I've been digging through Cloud's file, and here's what I've found:
It's really ugly and really hard to read. Here's what I can extract from reading; this is all manual work trying to interpret a very, very ambiguous file that has moves in no particular order whatsoever.
Jab1 is f7, does 3% damage, fixed knockback. Jab 2 and jab 3 are not fixed knockback and seem to do 4% each (so a full jab combo from Cloud is a decent 11% damage).
Some move I suspect is fsmash sets a bit on f6 (charge frame?), and then it hits three times starting on f19 for 3%, 2/3/4% (depends on which hitbox makes contact), and hten either 13% or 12% depending on which hitbox makes contact. It's a really powerful kill move (119 kbg/42 bkb/special angle 361).
Another move I suspect is utilt hits on frame 6 at a 95 degree angle (almost straight up but slightly behind the user) for 8% damage and again impressively high knockback (100 kbg/46 bkb). This move has four active frames.
Some weird move that I suspect is grab pummel hits on frame 5 for 3% damage and fixed knockback over only one active frame.
He has some two hit move I am not sure about that hits on frame 20 the first time and frame 24 the second time at a fairly low angle of 48 degrees. it does 7% damage with each hit and seems to have little kill power but some bonus shield damage. This might be get-up attack from lying on the ground? This move seems to be at least three places in Cloud's code which would make sense for a get-up attack (there are several essential identical versions of this on every character).
What I suspect to be fair or dair has a bit set on frame 3 (pre-hit auto-cancel?), hits on frame 18, and has a ton of hitboxes but the main meteor does 14% with 90 kbg/20 bkb while the late hit does 11%. That bit is unset on frame 43 (after-hit auto-cancel?).
What I suspect to be dsmash sets a bit on frame 3 (charge frame?), hits on frame 8 for 4% damage sending them nearly straight back, and then way later on frame 21 it hits for 12% damage with 96 kbg/35 bkb at a low angle (35 degrees).
Some move I suspect is an aerial sets a bit on frame 5 (pre-hit auto-cancel?), hits on frame 11 for 13% damage and decent knockback (special angle 361 which is a forward hit so this is probably not uair/95 kbg/20 bkb), makes a second hitbox that is nearly identical a frame later, stops being active at all the frame after that (so probably not nair), and has that bit clear which is probably an auto-cancel on frame 37. If I were a betting man, I'd go with this being bair, but don't quote me on that.
Cloud has some kind of special hitbox that does 10% damage and instantly breaks a shield (bonus 50 shield damage). It's also a really powerful kill move (120 kbg/100 bkb). I wonder if it's a part of Omnislash?
Some move hits on frame 9 for 11% damage at special angle 361 for 100 kbg/20 bkb with two active frames. It has nothing special going on with it at all which means it's not an aerial or a smash or a special move; my money is on ftilt.
Cloud's three grabs hit on frame 7, 10, and 11. There's no way for me to tell them apart, but I'd assume that's standing, running, pivot.
Some move on Cloud that could be an aerial hits on frame 4 for only 2.5% damage at various angles that tend to be pretty high (most of the hitboxes are at an 82 degree angle). On frame 8 it sets a bit that is the same bit I suspect is used for auto-cancel, and it sets another bit on f12. This could be Cloud's weird uair, but if so, does it really only do 2.5% damage?
Some move is a two hit move that hits on frame 9 for 11% damage with 60 degree angle/60 kbg/ 100 bkb with the first hit and then 8% with 65 degree angle, 50 kbg, and 100 bkb with a late hit. Overall this move is active for 10 frames with each hit taking up half of the time. Dash attack?
Some move I suspect to be usmash sets a bit on frame 7 (charge frame?), hits on frame 15 for 13%/12% damage at a high angle (83 degrees) with 96 kbg/40 bkb and then has a weaker hit starting on frame 18 that only does 8%.
One of Cloud's moves has hitboxes that keep generating up until frame 285, but they all do relatively low damage (the first one is way back on frame 7 for only 2%). Cross Slash? The intermediate part of Omnislash?
One of Cloud's aerials has a pre-hit autocancel ending on frame 5, hits on frame 11 with a 15% damage meteor (as well as various other hits), has a weaker later hit for 8%, is active for a long time (until frame 29), and has what looks like a post-hit auto-cancel on frame 37. This is either fair or dair, no way to tell them apart.
Cloud has something that uses special angle 366. I have no idea what that special angle does; it's very novel!
Summary:
frame 7 jab
frame 6 utilt
frame 9 ftilt
I didn't find dtilt
frame 19 fsmash that hits *really* hard
frame 15 usmash that hits kinda not so hard
frame 8 dsmash that does a total of 16% damage and seems incredible
I didn't find nair
Two meteors that hit on frames 15 and 18, both with pretty similar numbers all around.
Frame 11 bair that auto-cancels on frame 37 (that's pretty good!)
Grabs on frames 7/10/11
A super weird frame 4 uair that does like no damage that I have a feeling I'm misreading somehow.
Consider none of that reliable given how nearly unreadable the file was.
