Hydro is character of MK comicbooks. Lin Kuei, young friend of Sub-Zero. Not exactly his "padawan".
Killed by Scorpion.
He is infamous for being great character in Mortal Kombat Project (fanmade MK remake for MUGEN engine).
Hydro is playable as cyborg Lin Kuei controlling powers of water and ice. He borrows some tricks from Glacius (Killer Instinct alien) like dissolving himself and shaping his arms to cold weapons.
Great character and most popular MKP fan addition.
As DLC I am not sure. He is cool and whatever, but I would like to see Cyber Smoke and Tremor more. Another cyborg combining Sub-Zero's and Glacius's moves. He is in some way similar to Rain (cyborg + Rain + cold).
I still do not take the Cyber Sub Zero idea. They should know Hydro is popular, they are highly similar. They screwed Sub Zero instead
Terrible gameplay, but moves can be seen.
It seems like as soon as he stopped spamming his ice (?) clone, he started being unable to compete...
He looks pretty cool though. I'm sure NRS could make him different enough from rain and subby, although he looks pretty similar to what cyber sub zero would be.
