If power = speed squared x mass. Why arnt the fastest boxers the hardest hitters?

No, you are wrong. Although the units are same the formula isn't and the values aren't.

Energy (kinetic) is the scalar unit and it's represented by mv^2 / 2.

Torque is the vector unit and it's a VECTOR. The torque is the vector product of the force (which is vector) and displacement which is again a vector.

Energy is not the same as torque! You can't measure the power (damage) by torque - at least not in this direct way.

Thanks, It's been about 6 years since I've taken any type of a physics class.
