Fictional character likely to be first in identity parade? (7)

Ross

I believe the answer is:

persona

I'm a little stuck... Click here to teach me more about this clue!

'identity parade?' is the definition.
Although both the answer and definition are singular nouns, I cannot see how one could define the other.

'fictional character likely to be first' is the wordplay.
'fictional character' becomes 'pers' (I can't justify this - if you can you should believe this answer much more).
'likely' becomes 'on' (I've seen this in other clues).
'to be first' becomes 'a' (first letter of the alphabet).
'pers'+'on'+'a'='PERSONA'

'in' is the link.

Can you help me to learn more?

(Other definitions for persona that I've seen before include "No pears (anag.)" , "External aspect of character" , "Public image" , "Theatrical role" , "Assumed identity" .)
