Example of animated epic with humans chasing monsters, ultimately (8)
I believe the answer is:
specimen
'example' is the definition.
(I know that example can be written as specimen)
'animated epic with humans chasing monsters ultimately' is the wordplay.
'animated' indicates an anagram.
'with' means one lot of letters go next to another.
'humans' becomes 'men' (man is a kind of human).
'chasing' is a charade indicator (letters next to each other) (some letters chase after others).
'ultimately' says to take the final letters.
The final letter of 'monsters' is 's'.
'epic' anagrammed gives 'peci'.
'peci'+'men' is 'pecimen'.
'pecimen' after 's' is 'SPECIMEN'.
'of' is the link.
(Other definitions for specimen that I've seen before include "Part taken as example of whole or class" , "Sample to be studied" , "blood sample" , "Something used as an example" , "Sample taken for medical testing" .)
