A person who mediates and gets involved

[sherry_ibm]

Hi,

I would like to know the adjective that describes a person who mediates in a fight between two people in order to stop the fight but gets involved in the fight himself/herself.

I know that the word sounds like mediator, gladiator etc...i.e...it ends with "-ator", however I cannot recall what the word is.

Any other suggessions are welcome.

Thanks

Hi Soup,

Thanks for the inputs. However the word arbitrator has the following meanings as per the Cambridge Online Dictionary website:

"a person who has been officially chosen to make a decision between two people or groups who do not agree"...

This means that an arbitrator is supposed 2 be neutral in his approach.
It does not mention anywhere whether the person himself starts fighting with the two parties or not...

What I want to know is the word for the "arbitrator" who starts fighting with one or both the involved parties.

Suggessions are appreciated.
