'superhero' is the definition.
(comic book superhero)

'mired in kerfuffle punching cross' is the wordplay.
I cannot really understand how this works, but
an anagram of 'mired' is 'iderm' which is present in the answer.
'cross' could be 'span' (span can mean to cross or bridge) and 'span' is present in the leftover letters.
This accounts for all the letters.
This explanation may well be incorrect...
