A number of published V&V characters have a Body Power or Mutant Power that doubles one of their five basic characteristics of Strength, Endurance, Agility, Intelligence, or Charisma. One of the earliest examples is Behemoth of the Destroyers, who has Mutant Power (o Mutation in 1st edition) that doubles his Strength.

I say that this type of power also applies to training bonuses. If Behemoth trains in Strength, for example, he would then gain 2 points of Strength per level of training instead of 1 point.
