Do what Ender did. Beat the ever living shit out of him in front of this friends. Kick him when he's down. All that jazz. Then make a threat that even if he gets his brother in on this, even if he gets all his little shits together to beat on you, one day you will find the other kids alone and wail on them like there is no tomorrow. The problem with that is you have to make good on your promise and you look like a ruthless bastard.
The way I dealt with this when I was 13 was to Suplex the guy by the head. Didn't bother me ever again.
