Students that Matrix hero fights reportedly (9)
I believe the answer is:
neophytes
'students' is the definition.
(neophyte is a kind of student)
'matrix hero fights reportedly' is the wordplay.
'matrix hero' becomes 'neo' (I've seen this in another clue).
'fights reportedly' becomes 'phytes' (I can't justify this - if you can you should believe this answer much more).
'neo'+'phytes'='NEOPHYTES'
'that' acts as a link.
Can you help me to learn more?
(Other definitions for neophytes that I've seen before include "Novices" , "Newcomers" .)
