What martial artist might wear in unspoilt area (9)

'what martial artist' is the definition.
I don't know anything about this answer so I can't tell whether this works.

'wear in unspoilt area' is the wordplay.
I cannot really understand how this works, but
'wear' could be 'belt' (belt is a kind of wear) and 'belt' is present in the answer.
'area' could be 'green' (green is a kind of area) and 'green' is present in the answer.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).

'might' acts as a link.

Can you help me to learn more?
