Drip means to be transformed into superhero (9)
I believe the answer is:
spiderman
'superhero' is the definition.
(I know that Spiderman has the occupation superhero)
'drip means to be transformed' is the wordplay.
'to be transformed' indicates an anagram.
'drip'+'means'='dripmeans'
'dripmeans' is an anagram of 'SPIDERMAN'.
'into' is the link.
(Other definitions for spiderman that I've seen before include "Cartoon and film hero, kind of male arachnid" , "building worker" , "Cartoon-cinema hero of arachnid origin" , "suited vigilante" , "Film/comic book hero" .)
