Help This noob out....

I need help to understand the story a bit more...
I want to know who won every tournament story wise I know
Kazuya beat the first one
and thats all so can you help me out?

I think Heihachi defeated Devil to win the 2nd tourney and threw him into a volcano...then for Tekken 3 I'm pretty sure Jin defeated Ogre. In Tekken 4 Heihachi kidnapped Jin and brought him to the Honmaru temple where the three Mishima's fought it out. An army of Jack-5's halted the fight. No one won that one except Heihachi almost died. Then Tekken 5 came out and I'm not sure the official ending. My guess is either Heihachi or Wang won it after seeing all of the endings. It'll probably be out once Tekken 6 is released.

Can anyone add to that?

that makes sense one more thing they werent jack-5's they were Jack-4's the only jack not to be in a tournament they were the weaksest ones because they were mass -produced thats why heihachi ripped thruogh them like nothing...
