Tony's different from Mike (5)
I believe the answer is:
tyson
'mike' is the definition.
Both the answer and definition are singular nouns.
Maybe you can see an association between them that I don't see?
'tony's different' is the wordplay.
'different' is an anagram indicator.
'tonys' anagrammed gives 'TYSON'.
'from' acts as a link.
Can you help me to learn more?
(Other definitions for tyson that I've seen before include "US world heavyweight boxing champion, b.1966 -- English fast bowler, d. 2015" , "Mike --, US boxer" , "American world heavyweight champion, b. 1966" , "Mike ..., former US prizefighter" , "Youngest ever undisputed world heavyweight boxing champion, b, 1966" .)
