He would not stand a chance. How good are you at fighting someone who is taller and has about twice your body weight?
I was quite good at it actually. It only happened once. It was also the last fight I had. No one messed with me after that. The bully no longer bullied. You have to understand bullies are generally successful at bullying because no one fights back. They are scared pussies on the inside and have no idea what to do when someone fights back. If the kid can’t handle this on his own, then he should get someone or some people to beat the crap out of the bully. It’s that or live in fear. No one in charge wants to do anything about it so he has no other choice.
