Oh, you're talking about his bubble assist as one of the kombat modifiers, Ridley Prime? Yeah, true. WraithBlade just created a new thread talking about it.

Some of the kombat modifiers of MKX are assists - special attacks from other characters that pop up sometimes during the battle to harm someone. Examples: Cyrax' bomb, Kabal's blade, Rain's bubble. According to Wraithblade (don't remember if Tyler and Derek said exactly the same in the video), the characters who perform these moves are probably not in the game.

But I can't see Rain as an unplayable character in MKX now that they've done so much about him. The new costume, for example. The confirmation that he's alive during the game also, since he appears in the trailer. And he even kicked Kotal Kahn off a building. Usually unplayable characters don't do anything really important in the campaign. See Motaro in MK9 for example. But Rain kicked the emperor of Outworld off a building. That's something relevant to the story mode, and you don't see a random guy doing that. So I can't see why he wouldn't be playable.
