Kuvira’s fighting style.
Since Kuvira’s fight scene in ‘LOK: After All These Years’, I have seen a few discussions as to what Kuvira’s fighting style is based on? It has been said that it is Wing Chun Kuen (WCK) however I disagree with this. Although superficially similar to WCK there are many differences. One of the aforementioned discussions made reference to Kuvira’s high stances, however her stances are mostly higher versions of classical stances and not those seen in WCK. Many of Kuvira’s arm movements are also uncharacteristic of WCK, not adhering to WCK’s strict use of the centreline and the principle of economy of motion. Personally I think Kuvira’s style is a mixture of traditional Earthbending (Hung Gar), Toph’s style (Chuka Southern Mantis Fist), with a influences from the Pro-bending approach.
To reply to jvpamdg's comment of it looking like Pak Mei both Hung Gar and Chuka (as I’m sure you will know) are Southern Chinese and share many concepts and principles with Pak Mei. I believe I’m right in saying that Pak Mei and Chuka are both Hakka (Guest Family) styles and are closely associated.
