According to Newton's second law of motion, the force needed to move an object is directly proportional to its mass. This means that if the mass of an object increases, the force required to move it must also increase proportionally.

Mathematically, the relationship between force (F), mass (m), and acceleration (a) is given by the equation:

```

F = m * a

```

In this case, if Hunter's mass changes from 1 kg to 200 kg, the force required to move him will become 200 times greater.

Therefore, if Hunter's mass increases from 1 kg to 200 kg, the force required to move him will also increase by 200 times.
