Maybe Joan's hero? (5)

I believe the answer is:

jason

'hero?' is the definition.
(I've seen this before)

'maybe joan's' is the wordplay.
'maybe' indicates an anagram.
'joans' with letters rearranged gives 'JASON'.

(Other definitions for jason that I've seen before include "Argonaut captain" , "Chief Argonaut" , "Greek hero, leader of the Argonauts" , "Argonaut leader" , "Greek hero, captain of the Argo" .)

I've seen this clue in the Evening Standard.
