ShadoVao posted...Speaking totally objectively, the only people on that list who would definitely beat Nina are Kaz, Hei, Lars and Hwoarang.
SInce Hei and Kaz have each won a tournament, they'd have to have beaten Nina at some point. Lars is seen to be at least Kaz's equal (they traded blows in T6 SC, which is cliche-speak for equal power), yet inferior to Jin (since Jin owned Kaz in T4). I assume Jin beats Nina too, since he won T3,4 and 5.
Hwoarang beat Jin in T5 (though Jin's story mode interludes may indicate he wasn't focused at the time), which means he should beat Nina, assuming (IF a>b and b>c, then a>c) is true.
Not necessarily. Nina could have been eliminated by them, but also by anybody else who was later eliminated themselves without ever facing Hei or Kaz. That's the problem with single-elimination tournaments in real life, too... you can never really know who should actually be ranked 2nd, since anyone eliminated by first could be the actual second-best entrant.
As far as the transitive property goes, it might matter in terms of innate power (like being a deity or demon), but a think that there's often a paper-rock-scissors element possible in something as complex as fighting. Also, luck. If two equally matched fighters square off, one has to win by luck if nothing else, otherwise they draw and either both move forward or are both eliminated, depending on the tournament rules.
