If he is Chemosabe, then who am I?

The MR being so clever has named himself CHEMOSABE as we begin our journey through the chemo and radiation world of cancer treatment.  My question is...if he is Chemosabe, then who am I?
Every Chemosabe has to have a side kick.
It's a known fact.
Every Super Hero has his buddy.
Every comic has their straight man.
Every Lucy has her Ethel
Fred has his Barney.
So....if he's Chemosabe, who should I be.

The obvious choice would be Tonto.
But, maybe I favor another name.
Maybe I'd like to be a different side kick.
