jip, 43, lightning, dash, uppercut, dash, 43, waterbubble, 43, AquaSmash
Its more of muscle memory for me lol but try inputting the dash right after the uppercut. Pause for a bit until the actual dash animation takes effect,,, then continue with the 43
After a bit more experimentation, I found you can end this combo with 4,3xxBubble for about 34 to 37% damage and bubble shenanigans. Unfortunately, the timing is insanely strict: the best advice I can give is to time the 4,3xxRoundhouse so that the 4,3 barely hit the opponent's hitbox (talking mere pixels here). Is there a better bubble reset?
If I just hit an X-Ray on its own, I normally follow up with 4,3,B4 like in the X-Ray combo I listed above. Good way to tack on some extra damage. I use 4,3 xx water splash if I'm worried about a wake-up attack.
When I land the geyser kick I do: 43 bubble, 43 lightning, RH, 43 teleport. Regular aqua splash whiffs, but I think you can add an ex aqausplash instead of the teleport.
43 squirt or 4 Geyser. You can't get much off of an X-ray unless you're in the corner, which is where I use X-ray mostly.
, or Geyser/Lightning/Aqua Splash/Teleport Geyser X2, - 50%+
Does the 4,3,b3 give you more advantage than 4,3xxgeyser? Because 4,3xxgeyser times three does more damage.
If your back is too the corner and the opponent is anywhere on screen:
yea, you could do a 3rd geyser if you want
What combo do you recommend after the superkick? I think something that ends in the bubble would be the best choice.
If your back is too the corner and the opponent is anywhere on screen:
You can do 2 into 43 lightning then bubble. That what i use. I think its 26% plus the RH pressure or grab.
Well, I know that its very difficult to win with Rain if you don't get the MAX damage from every situation, so everytime the opponent eats a SuperKick, do
Waterbubble, Uppercut, Lightning, Geyser, its around 40-42% just for trying to poke out of his Superkick cancels. Superkick, this will get 44%, you can always push the damage with 
Aqua Splash, but its best to take the opponents meter with the Waterbubble, and use only one bar per combo. 
Waterbubble, then Uppercut, Lightning, Superkick, Geyser Lightning, Uppercut, Waterbubble, you can end with , or Geysey, but if you want to reset them after the bubble, you will need at least one Superkick Cancel into another string to make up for the damage you lost by not finishing the combo, but you could lucky and have the opponent poke out again at the wrong time.
If your execution is gdlk then you can use; dash uppercut dash 4,3xxlightning dash 4,3xxbubble for almost 40%
