Are tekken combos ~ similar in most games?

I’m not sure what to expect from the coming Tekken 7, it premieres on PC using Unreal4 so I will be able to get it sooner than the normal year or so after release. Does Tekken have a reputation of using similar moves/combos for a given character? Scorpion in Injustice is near identical to Scorpion in MK9, for example.

Yes, the Tekken roster for the most part use similar moves to previous games with a few exceptions. I’m no Tekken expert, but I play TR and T6 (PSP), and I can say that the combos that I perform on my PSP can be replicated on the PS3 which is Tekken Revolution.
