Kintaro is a Shokan like Goro. I don't the tiger stripes mean anyhting in paticular.
According to a strategy guide Kintaro was disintergrated by Raiden during MK2, but that was never confirmed to be canon.
Kintaro is mentioned as being one of the generals leading Kahn's armies into Edenia during Konquest. But, it's Konquest and very little of it should be taken as proof.
I think Kintaro's alive somewhere. The creaters just haven't done anyhting with him.

i know and that fucking sucks..i like goro...but kintaro was alot better and cooler! next game should be shao kahn and kintaro!!! and hell why not throw in a goro zombie!! lmfao! that would rule!
