Crossword Genius

A violent character (5)

Ross

I believe the answer is:

rambo

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

'a violent' is the definition.
I know nothing about this answer so I cannot tell whether it can be defined by this definition.

'character' is the wordplay.
I cannot really see how this works, but
'character' could be 'r' and 'r' is located in the answer.
The remaining letters 'ambo' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).

Can you help me to learn more?

(Other definitions for rambo that I've seen before include "Character given to mindless violence" , "Stallone film character" , "Brainless hero" , "Character relying on brute force" , "Tough man (films)" .)

I've seen this clue in the Evening Standard.
