Just started watching this set of videos on Youtube, uploaded by user SlashColumbiaRevenge, which features what is apparently considered as the top 10 ranking of characters for KOF97 in China.
Not having played KOF97 properly for a long time now i'm not really in a position to comment on the rankings, but you can see some really nice set ups, combos and tactics in these videos. (All taken from real matches.)
7. Goro Daimon
6. Blue Mary
