[edit] Tekken Force

Is there a certain variable that determines whether you will fight Panda or Kuma 2nd, like gender of the player's character or something? --RJX

Well, I started playing through Tekken 4's Tekken Force mode with all 23 of the characters recently, and I finished today. I recorded who I fought at each stage and what outfit they were in by writing it down on paper. I'll just tell you the Kuma / Panda results.

1. Paul Phoenix - Panda.
2. Nina Williams - Panda.
3. Violet - Panda.
4. Lee Chaolan - Kuma.
5. Miharu Hirano - Panda.
6. Ling Xiaoyu - Kuma.
7. Craig Marduk - Panda.
8. Steve Fox - Kuma.
9. Heihachi Mishima - Panda.
10. Combot - Panda.
11. Lei Wulong - Kuma.
12. Panda - Kuma.
13. Kuma - Panda.
14. Hwoarang - Panda.
15. Julia Chang - Kuma.
16. King - Panda.
17. Eddy Gordo - Kuma.
18. Christie Monteiro - Panda.
19. Bryan Fury - Kuma.
20. Kazuya Mishima - Kuma.
21. Marshall Law - Panda.
22. Yoshimitsu - Panda.
23. Jin Kazama - Kuma.

The number of times I encountered Kuma: 11.
The number of times I encountered Panda: 13.

I think it's just random. JunKazamaFan 03:03, 25 September 2007 (PDT)

If you want to make that statement one step closer to being an accepted "fact", you should take the character you are best with and play through the mode 3-4 times, using the same outfit, to make sure it's the same opponent each time. On the fourth test, try using an alternate outfit and see if Kuma/Panda changes as well (theory based on nothing at all, but hey). --Hecko 04:05, 25 September 2007 (PDT)

All right. I'll try doing this. JunKazamaFan 04:33, 25 September 2007 (PDT)

Ok. Unfortunately, I do not have the time to that stuff -_-. --Sakura 14:41, 25 September 2007 (PDT)
